DRUG INTERACTIONS
Acebutolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Atenolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Carteolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Colesevelam: (Moderate) In patients with type 2 diabetes mellitus receiving insulins, colesevelam increased serum triglyceride concentrations by 22% compared to placebo. Monitor patients for increase in triglyceride concentrations. Discontinue colesevelam if triglyceride concentrations are > 500 mg/dl or if hypertriglyceridemia-induced pancreatitis occurs.
Conjugated Estrogens: (Minor) Patients receiving antidiabetic agents should be periodically monitored for changes in glycemic control when hormone therapy is instituted or discontinued. Estrogens can decrease the hypoglycemic effects of antidiabetic agents by impairing glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day in combined oral contraceptives (COCs), which are not commonly used in practice since the marketing of lower dose COCs, patches, injections and rings. The presence or absence of a concomitant progestin may influence the significance of any hormonal effect on glucose homeostasis.

Conjugated Estrogens; Medroxyprogesterone: (Moderate) Incretin mimetics slow gastric emptying and should be used with caution in patients receiving oral medications that require minimum threshold concentrations for efficacy, such as progestin-only oral contraceptives. Some incretin mimetics make specific recommendations to reduce the risk for interaction. Taking an oral contraceptive (OC) at least 1 hour before an incretin mimetic injection should reduce the risk of an effect on contraceptive or hormonal absorption. For Lixisenatide, the manufacturer recommends taking the OC 1 hour before injection or 11 hours after injection to reduce the effect on absorption. Additionally, progestins can impair glucose tolerance. Monitor blood glucose more carefully during initiation or discontinuation of hormone replacement or hormonal contraceptive treatment. Patients receiving incretin mimetics should be closely monitored for changes in glycemic control.

Dorzolamide; Timolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Enalapril, Enalaprilat: (Moderate) ACE inhibitors may enhance the hypoglycemic effects of insulin or other antidiabetic agents by improving insulin sensitivity. Patients receiving these drugs concomitantly with antidiabetic agents should be monitored for changes in glycemic control. (Moderate) Monitor patients receiving angiotensin-converting enzyme inhibitors (ACE inhibitors) concomitantly with insulin for changes in glycemic control. ACE inhibitors may enhance the hypoglycemic effects of insulin by improving insulin sensitivity. In addition, ACE inhibitors have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other cardiac disease.

Patients receiving these drugs concomitantly with antidiabetic agents should be monitored for changes in glycemic control. (Moderate) Monitor patients receiving angiotensin-converting enzyme inhibitors (ACE inhibitors) concomitantly with insulin for changes in glycemic control. ACE inhibitors may enhance the hypoglycemic effects of insulin by improving insulin sensitivity. In addition, ACE inhibitors have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other cardiac disease. (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Ephedrine: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Ephedrine; Guaifenesin: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically.

To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Erythromycin; Sulfisoxazole: (Moderate) Sulfonamides may enhance the hypoglycemic action of antidiabetic agents; patients with diabetes mellitus should be closely monitored during sulfonamide treatment. Sulfonamides may induce hypoglycemia in some patients by increasing the secretion of insulin from the pancreas. Patients at risk include those with compromised renal function, those fasting for prolonged periods, those that are malnourished, and those receiving high or excessive doses of sulfonamides.
Esmolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Esterified Estrogens: (Minor) Patients receiving antidiabetic agents should be periodically monitored for changes in glycemic control when hormone therapy is instituted or discontinued. Estrogens can decrease the hypoglycemic effects of antidiabetic agents by impairing glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day in combined oral contraceptives (COCs), which are not commonly used in practice since the marketing of lower dose COCs, patches, injections and rings. The presence or absence of a concomitant progestin may influence the significance of any hormonal effect on glucose homeostasis.
Esterified Estrogens; Methyltestosterone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements.

Estradiol Cypionate; Medroxyprogesterone: (Moderate) Incretin mimetics slow gastric emptying and should be used with caution in patients receiving oral medications that require minimum threshold concentrations for efficacy, such as progestin-only oral contraceptives. Some incretin mimetics make specific recommendations to reduce the risk for interaction. Taking an oral contraceptive (OC) at least 1 hour before an incretin mimetic injection should reduce the risk of an effect on contraceptive or hormonal absorption. For Lixisenatide, the manufacturer recommends taking the OC 1 hour before injection or 11 hours after injection to reduce the effect on absorption.

Ethanol: (Moderate) Patients should be advised to limit alcohol ingestion when treated with an antidiabetic agent. Alcohol inhibits gluconeogenesis, which can contribute to or increase the risk for hypoglycemia. In some patients, hypoglycemia can be prolonged. If a patient with diabetes ingests alcohol, they should be counselled to avoid ingestion of alcohol on an empty stomach, which increases risk for low blood sugar. Patients should also be aware of the carbohydrate intake provided by certain types of alcohol in the diet, which can contribute to poor glycemic control. If a patient chooses to ingest alcohol, they should monitor their blood glucose frequently. Many non-prescription drug products may be formulated with alcohol; instruct patients to scrutinize product labels prior to consumption.

Fexofenadine; Pseudoephedrine: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Fibric acid derivatives: (Moderate) Dose reductions and increased frequency of glucose monitoring may be required when antidiabetic agents are administered with fibric acid derivatives (e.g., clofibrate, fenofibric acid, fenofibrate, gemfibrozil). Fibric acid derivatives may enhance the hypoglycemic effects of antidiabetic agents through increased insulin sensitivity and decreased glucagon secretion.
Fludrocortisone: (Moderate) Monitor patients receiving insulin closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Flunisolide: (Moderate) Monitor patients receiving insulin closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents.

Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Fluoxetine: (Moderate) In patients with diabetes mellitus, fluoxetine may alter glycemic control. Hypoglycemia has occurred during fluoxetine therapy. Hyperglycemia has developed in patients with diabetes mellitus following discontinuation of the drug. The dosage of insulin and/or other antidiabetic agents may need to be adjusted when therapy with fluoxetine is instituted or discontinued.
Fluoxymesterone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Fluphenazine: (Minor) Phenothiazines, especially chlorpromazine, may increase blood glucose concentrations. Hyperglycemia and glycosuria have been reported. Patients who are taking antidiabetic agents should monitor for worsening glycemic control when a phenothiazine is instituted.

Fosamprenavir: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control, specifically hyperglycemia, when anti-retroviral protease inhibitors are instituted. New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors. Another possible mechanism is impairment of beta-cell function. Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of protease inhibitors. Patients taking antidiabetic agents should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.
Fosinopril: (Moderate) ACE inhibitors may enhance the hypoglycemic effects of insulin or other antidiabetic agents by improving insulin sensitivity.

(Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Fosphenytoin: (Minor) Fosphenytoin and other hydantoins have the potential to increase blood glucose and thus interact with antidiabetic agents pharmacodynamically. Monitor blood glucose for changes in glycemic control. Dosage adjustments may be necessary in some patients. (Minor) Fosphenytoin can decrease the hypoglycemic effects of incretin mimetics by producing an increase in blood glucose levels. Patients receiving incretin mimetics should be closely monitored for signs indicating loss of diabetic control when therapy with a hydantoin is instituted. Conversely, patients should be closely monitored for signs of hypoglycemia when therapy with a hydantoin is discontinued.
Furosemide: (Minor) Monitor patients receiving insulin closely for worsening glycemic control when bumetanide, furosemide, and torsemide are instituted. Bumetanide, furosemide, and torsemide may cause hyperglycemia and glycosuria in patients with diabetes mellitus, probably due to diuretic-induced hypokalemia. Because of this, a potential pharmacodynamic interaction exists between these drugs and all antidiabetic agents.
Garlic, Allium sativum: (Moderate) Patients receiving antidiabetic agents should use dietary supplements of Garlic, Allium sativum with caution. Constituents in garlic might have some antidiabetic activity, and may increase serum insulin levels and increase glycogen storage in the liver. Monitor blood glucose and glycemic control. Patients with diabetes should inform their health care professionals of their intent to ingest garlic dietary supplements. Some patients may require adjustment to their hypoglycemic medications over time. One study stated that additional garlic supplementation (0.05 to 1.5 grams PO per day) contributed to improved blood glucose control in patients with type 2 diabetes mellitus within 1 to 2 weeks, and had positive effects on total cholesterol and high/low density lipoprotein regulation over time. It is unclear if hemoglobin A1C is improved or if improvements are sustained with continued treatment beyond 24 weeks. Other reviews suggest that garlic may provide modest improvements in blood lipids, but few studies demonstrate decreases in blood glucose in diabetic and non-diabetic patients. More controlled trials are needed to discern if garlic has an effect on blood glucose in patients with diabetes. When garlic is used in foods or as a seasoning, or at doses of 50 mg/day or less, it is unlikely that blood glucose levels are affected to any clinically significant degree.
Gemfibrozil: (Moderate) Dose reductions and increased frequency of glucose monitoring may be required when antidiabetic agents are administered with fibric acid derivatives (e.g., clofibrate, fenofibric acid, fenofibrate, gemfibrozil). Fibric acid derivatives may enhance the hypoglycemic effects of antidiabetic agents through increased insulin sensitivity and decreased glucagon secretion.
Glecaprevir; Pibrentasvir: (Moderate) Closely monitor blood glucose levels if glecaprevir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as glecaprevir. (Moderate) Closely monitor blood glucose levels if pibrentasvir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as pibrentasvir.
Glimepiride; Rosiglitazone: (Major) Use of insulins with rosiglitazone is not recommended by the manufacturer due to a potential increased risk for edema or heart failure. If heart failure develops in a patient receiving insulin and a thiazoladinedione, manage the patient according to standards of care, and discontinue or consider reducing the dose of the thiazoladinedione. Since the incidence of hypoglycemia may also be higher with combined therapy, patients should also be instructed to monitor blood glucose concentrations more frequently. In five 26-week trials involving patients with type 2 diabetes, rosiglitazone added to insulin therapy (n=867) was compared with insulin therapy alone (n=663). These trials included patients with chronic diabetes and a high prevalence of coexisting medical conditions, including peripheral neuropathy, retinopathy, ischemic heart disease, vascular disease, and congestive heart failure. In these clinical studies, an increased incidence of heart failure and other cardiovascular adverse events was seen in patients receiving combination rosiglitazone and insulin therapy compared to insulin monotherapy; the incidence of new onset or exacerbated heart failure was 0.9% in patients treated with insulin alone vs. 2% in patients treated with insulin plus rosiglitazone. Some of the patients who developed cardiac failure on combination therapy during the double blind part of the studies had no known prior evidence of congestive heart failure, or pre-existing cardiac condition. Additionally, the results of a meta-analysis that included the same 5 randomized, controlled trials mentioned previously indicate that the rate of myocardial ischemia may be increased in patients taking rosiglitazone in combination with insulin; the incidence of myocardia ischemia was 1.4% in patients receiving insulin monotherapy vs. 2.8% in patients receiving rosiglitazone and insulin combination therapy (OR 2.1 95% CI 0.9-5.1). The cardiovascular events were noted at doses of both 4 mg/day and 8 mg/day of rosiglitazone. In a sixth 26-week study, patients with baseline congestive heart failure were excluded; in this study, compared to insulin monotherapy (n=158), the addition of rosiglitazone to insulin therapy (n=161) did not increase the risk of congestive heart failure. One each of myocardial ischemia and sudden death were reported in patients taking combination therapy compared to zero patients taking insulin monotherapy. When rosiglitazone was added to insulin therapy, the incidence of hypoglycemia was higher with 8 mg/day of rosiglitazone (67%) compared to 4 mg/day (53%).
Glipizide; Metformin: (Moderate) Coadministration of metformin with an insulin may increase the risk of hypoglycemia. Insulins are known to cause hypoglycemia. To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Glucagon: (Minor) Caution should be exercised when glucagon is used as a diagnostic aid for radiologic examination in patients taking insulin. Insulin reacts antagonistically towards glucagon. Monitor the patient receiving glucagon for a diagnostic procedure for the desired clinical effects. There is no concern when glucagon is used to treat severe hypoglycemia. If a patient receives glucagon due to severe hypoglycemia by a family member or caregiver, they should alert their health care provider so that insulin treatment may be adjusted, if needed.

Inhibitors of MAO type A have been shown to prolong the hypoglycemic response to insulin and other antidiabetic agents.
Isoproterenol: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Labetalol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Lanreotide: (Moderate) Monitor blood glucose levels regularly in patients with diabetes, especially when lanreotide treatment is initiated or when the dose is altered. Adjust treatment with antidiabetic agents as clinically indicated. Lanreotide inhibits the secretion of insulin and glucagon.

Lidocaine; Epinephrine: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Linagliptin; Metformin: (Moderate) Coadministration of metformin with an insulin may increase the risk of hypoglycemia. Insulins are known to cause hypoglycemia. To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Linezolid: (Moderate) Hypoglycemia, including symptomatic episodes, has been noted in post-marketing reports with linezolid in patients with diabetes mellitus receiving therapy with antidiabetic agents, such as insulin and oral hypoglycemic agents. Diabetic patients should be monitored for potential hypoglycemic reactions while on linezolid. If hypoglycemia occurs, discontinue or decrease the dose of the antidiabetic agent or discontinue the linezolid therapy.

In addition, ACE inhibitors have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other cardiac disease. (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Lithium: (Moderate) Lithium may cause variable effects on glycemic control when used in patients receiving antidiabetic therapy iincluding incretin mimetics. Blood glucose concentrations should be closely monitored if lithium is taken by the patient. Dosage adjustments of insulin may be necessary.

Adequate blood glucose monitoring should be continued and followed.
Lonapegsomatropin: (Moderate) Patients with diabetes mellitus should be monitored closely during somatropin (recombinant rhGH) therapy. Antidiabetic drugs (e.g., insulin or oral agents) may require adjustment when somatropin therapy is instituted in these patients. Growth hormones, such as somatropin, may decrease insulin sensitivity, leading to glucose intolerance and loss of blood glucose control. Therefore, glucose levels should be monitored periodically in all patients treated with somatropin, especially in those with risk factors for diabetes mellitus.
Loop diuretics: (Minor) Loop diuretics, such as bumetanide, furosemide, and torsemide, may cause hyperglycemia and glycosuria in patients with diabetes mellitus, probably due to diuretic-induced hypokalemia. Because of this, a potential pharmacodynamic interaction exists between these drugs and all antidiabetic agents, including incretin mimetics. This interference can lead to a loss of diabetic control, so diabetic patients should be monitored closely if these drugs are initiated.
Lopinavir; Ritonavir: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control, specifically hyperglycemia, when anti-retroviral protease inhibitors are instituted. New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors. Another possible mechanism is impairment of beta-cell function. Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of protease inhibitors. Patients taking antidiabetic agents should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.

Lorcaserin: (Moderate) In general, weight reduction may increase the risk of hypoglycemia in patients with type 2 diabetes mellitus treated with antidiabetic agents, such as insulin and/or insulin secretagogues (e.g., sulfonylureas). In clinical trials, lorcaserin use was associated with reports of hypoglycemia. Blood glucose monitoring is warranted in patients with type 2 diabetes prior to starting and during lorcaserin treatment. Dosage adjustments of anti-diabetic medications should be considered. If a patient develops hypoglycemia during treatment, adjust anti-diabetic drug regimen accordingly. Of note, lorcaserin has not been studied in combination with insulin.
Losartan: (Moderate) Angiotensin II receptor antagonists may enhance the hypoglycemic effects of antidiabetic agents by improving insulin sensitivity. In addition, angiotensin II receptor antagonists have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other cardiac disease.

Aggravation of diabetes mellitus has been reported. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.
Macimorelin: (Major) Avoid use of macimorelin in patients receiving exogenous insulin therapy. In addition, healthcare providers are advised to discontinue insulin therapy and observe a sufficient washout period before administering macimorelin. Use of exogenous insulin may impact the accuracy of the macimorelin growth hormone test by directly affecting pituitary growth hormone secretion and by transiently elevating growth hormone concentrations.
Magnesium Salicylate: (Moderate) Salicylates, by inhibiting prostaglandin E2 synthesis, can indirectly increase insulin secretion. Thus, salicylates can decrease blood glucose concentrations. In large doses, salicylates uncouple oxidative phosphorylation, deplete hepatic and muscle glycogen, and cause hyperglycemia and glycosuria. After acute overdose, aspirin can cause either hypo- or hyperglycemia. Large doses of aspirin should be used cautiously in patients receiving antidiabetic agents. Monitor blood glucose closely during coadministration. (Moderate) Use large doses of aspirin cautiously in patients receiving insulin.

Patients should be advised to eat within 20 minutes of mecasermin administration. Glucose monitoring is important when initializing or adjusting mecasermin therapies, when adjusting concomitant antidiabetic therapy, and in the event of hypoglycemic symptoms. An increased risk for hypoglycemia is possible. The hypoglycemic effect induced by IGF-1 activity may be exacerbated. The amino acid sequence of mecasermin (rh-IGF-1) is approximately 50 percent homologous to insulin and cross binding with either receptor is possible. Treatment with mecasermin has been shown to improve insulin sensitivity and to improve glycemic control in patients with either Type 1 or Type 2 diabetes mellitus when used alone or in conjunction with insulins.

Metformin: (Moderate) Coadministration of metformin with an insulin may increase the risk of hypoglycemia. Insulins are known to cause hypoglycemia. To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Metformin; Repaglinide: (Moderate) Coadministration of metformin with an insulin may increase the risk of hypoglycemia. Insulins are known to cause hypoglycemia. To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Metformin; Rosiglitazone: (Major) Use of insulins with rosiglitazone is not recommended by the manufacturer due to a potential increased risk for edema or heart failure. If heart failure develops in a patient receiving insulin and a thiazoladinedione, manage the patient according to standards of care, and discontinue or consider reducing the dose of the thiazoladinedione. Since the incidence of hypoglycemia may also be higher with combined therapy, patients should also be instructed to monitor blood glucose concentrations more frequently. In five 26-week trials involving patients with type 2 diabetes, rosiglitazone added to insulin therapy (n=867) was compared with insulin therapy alone (n=663). These trials included patients with chronic diabetes and a high prevalence of coexisting medical conditions, including peripheral neuropathy, retinopathy, ischemic heart disease, vascular disease, and congestive heart failure. In these clinical studies, an increased incidence of heart failure and other cardiovascular adverse events was seen in patients receiving combination rosiglitazone and insulin therapy compared to insulin monotherapy; the incidence of new onset or exacerbated heart failure was 0.9% in patients treated with insulin alone vs. 2% in patients treated with insulin plus rosiglitazone. Some of the patients who developed cardiac failure on combination therapy during the double blind part of the studies had no known prior evidence of congestive heart failure, or pre-existing cardiac condition. Additionally, the results of a meta-analysis that included the same 5 randomized, controlled trials mentioned previously indicate that the rate of myocardial ischemia may be increased in patients taking rosiglitazone in combination with insulin; the incidence of myocardia ischemia was 1.4% in patients receiving insulin monotherapy vs. 2.8% in patients receiving rosiglitazone and insulin combination therapy (OR 2.1 95% CI 0.9-5.1). The cardiovascular events were noted at doses of both 4 mg/day and 8 mg/day of rosiglitazone. In a sixth 26-week study, patients with baseline congestive heart failure were excluded; in this study, compared to insulin monotherapy (n=158), the addition of rosiglitazone to insulin therapy (n=161) did not increase the risk of congestive heart failure. One each of myocardial ischemia and sudden death were reported in patients taking combination therapy compared to zero patients taking insulin monotherapy. When rosiglitazone was added to insulin therapy, the incidence of hypoglycemia was higher with 8 mg/day of rosiglitazone (67%) compared to 4 mg/day (53%). (Moderate) Coadministration of metformin with an insulin may increase the risk of hypoglycemia. Insulins are known to cause hypoglycemia. To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Metformin; Saxagliptin: (Moderate) Coadministration of metformin with an insulin may increase the risk of hypoglycemia. Insulins are known to cause hypoglycemia. To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Metformin; Sitagliptin: (Moderate) Coadministration of metformin with an insulin may increase the risk of hypoglycemia. Insulins are known to cause hypoglycemia. To manage hypoglycemic risk, lower doses of insulin may be needed. Monitor blood sugar and adjust insulin dosage as clinically indicated.
Methamphetamine: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Methazolamide: (Minor) Carbonic anhydrase inhibitors may alter blood sugar. Both hyperglycemia and hypoglycemia have been described in patients treated with acetazolamide. This should be taken into consideration in patients with impaired glucose tolerance or diabetes mellitus who are receiving antidiabetic agents. Monitor blood glucose and for changes in glycemic control and be alert for evidence of an interaction.
Methohexital: (Minor) The risk of developing hypothermia is increased when methohexital is used with hypothermia-producing agents such as ethanol, insulins, phenothiazines, or other general anesthetics.
Methyclothiazide: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Methylphenidate: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Methylprednisolone: (Moderate) Monitor patients receiving insulin closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Methyltestosterone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Metoclopramide: (Moderate) Increased GI motility by metoclopramide may increase delivery of food to the intestines and increase blood glucose. The dosing of insulin may require adjustment in patients who receive metoclopramide concomitantly.
Metolazone: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Metoprolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Metoprolol; Hydrochlorothiazide, HCTZ: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels.

While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present. (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Metreleptin: (Moderate) Use caution when administering metreleptin to patients treated with concomitant insulins or insulin secretagogue therapy (i.e., sulfonylureas, nateglinide, repaglinide). In clinical evaluation of metreleptin, hypoglycemia occurred in 13% of patients with generalized lipodystrophy. Most reported cases occurred with concomitant insulin use, with or without oral antihyperglycemic agents. Closely monitor blood glucose in patients on concomitant insulin or insulin secretagogue therapy. Dosage adjustments to their antihyperglycemic medications may be necessary.
Metyrapone: (Moderate) In patients taking insulin or other antidiabetic agents, the signs and symptoms of acute metyrapone toxicity (e.g., symptoms of acute adrenal insufficiency) may be aggravated or modified.
Midodrine: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Moexipril: (Moderate) ACE inhibitors may enhance the hypoglycemic effects of insulin or other antidiabetic agents by improving insulin sensitivity. Patients receiving these drugs concomitantly with antidiabetic agents should be monitored for changes in glycemic control. (Moderate) Monitor patients receiving angiotensin-converting enzyme inhibitors (ACE inhibitors) concomitantly with insulin for changes in glycemic control. ACE inhibitors may enhance the hypoglycemic effects of insulin by improving insulin sensitivity. In addition, ACE inhibitors have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other cardiac disease.
Mometasone: (Moderate) Monitor patients receiving insulin closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Monoamine oxidase inhibitors: (Moderate) Monitor patients receiving monoamine oxidase inhibitors (MAOIs) concomitantly with insulin for changes in glycemic control. Animal data indicate that MAOIs may stimulate insulin secretion. Inhibitors of MAO type A have been shown to prolong the hypoglycemic response to insulins. (Moderate) Serum glucose should be monitored closely when monoamine oxidase inhibitors (MAOIs) are added to any regimen containing antidiabetic agents. Inhibitors of MAO type A have been shown to prolong the hypoglycemic response to insulin and other antidiabetic agents.
Nadolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Nandrolone Decanoate: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Naproxen; Pseudoephedrine: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Nebivolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels.

While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Nebivolol; Valsartan: (Moderate) Angiotensin II receptor antagonists may enhance the hypoglycemic effects of antidiabetic agents by improving insulin sensitivity. In addition, angiotensin II receptor antagonists have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other ca
