Interactions

Drug interactions can alter the way your medications work or put you at risk for serious side effects. This document does not include every possible drug interaction. Maintain a list of all the products you use (including prescription and nonprescription drugs, as well as herbal supplements) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medications without first consulting your doctor.

Beta-blocker medications (such as metoprolol, propranolol, and glaucoma eye drops like timolol) can help prevent the fast/pounding heartbeat that occurs when your blood sugar falls too low (hypoglycemia). These medications have no effect on other symptoms of low blood sugar, such as dizziness, hunger, or sweating.

Many medications might alter your blood sugar, making it more difficult to manage. Discuss the potential effects of the drug on your blood sugar with your doctor or pharmacist before you begin, stop, or modify any medication. As advised, check your blood sugar frequently, and inform your doctor of the results. If you experience high or low blood sugar symptoms, contact your doctor right away. (See also the section on side effects.) Your diabetic medication, exercise routine, or diet may need to be changed by your doctor.
