To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval.
Some products that may interact with this drug include: NPH insulin, "water pills"/diuretics (such as furosemide, thiazide diuretics including hydrochlorothiazide).
Other medications can affect the removal of repaglinide from your body, which may affect how repaglinide works. Examples include cyclosporine, gemfibrozil, trimethoprim, azole antifungals (such as itraconazole, ketoconazole), macrolide antibiotics (such as clarithromycin, erythromycin), rifamycins (such as rifabutin), St. John's wort, among others.
Other drugs can affect the kidneys. This effect may slow down the removal of metformin from the body. Metformin may also slow down the removal of other drugs. Examples of affected drugs include some antibiotics (such as cephalexin, penicillin) and probenecid.
Many drugs can affect your blood sugar levels, making it more difficult to control your blood sugar. Examples include corticosteroids (such as prednisone), psychiatric medicines (such as olanzapine), fluoroquinolone antibiotics (such as ciprofloxacin), among others. Ask your doctor or pharmacist how often to check your blood sugar. Tell your doctor about the results and of any symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your diabetes medication, exercise program, or diet.
Beta-blocker medications (such as metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar level falls too low (hypoglycemia). Other symptoms of low blood sugar such as dizziness, hunger, or sweating are unaffected by these drugs.
Check the labels on all your medicines (such as cough-and-cold products) carefully. Some products may contain sugar or alcohol and may affect your blood sugar levels. Ask your doctor or pharmacist about using these products safely.
Cimetidine is a nonprescription drug that is commonly used to treat extra stomach acid. Because it may interact with metformin, ask your pharmacist about other products to treat stomach acid.
Other medications can affect the results of urine tests for sugar or ketones. Consult your doctor or pharmacist for more information.
