When looking at drugs that may affect glucose levels, we need to invoke some special rules. There are medicines that can cause hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar) in diabetic and in nondiabetic patients. These pharmaceuticals will have an even greater effect on the patient with diabetes and should either be avoided or used with vigilance and with a consideration of changing the amount of the diabetes medication used.

Some medications are found to have a possible effect on the patient with diabetes but can be used more freely. Again, however, vigilance is warranted.

There is also a category of medications that interact with diabetes medications. These medications don’t actually cause hypoglycemia or hyperglycemia, but rather they interfere with the action of the medicines you are taking for your diabetes. Whenever you start a new medication, it’s important to understand if it will affect your blood sugars or interfere with your blood sugar medication. In either case, it is important to monitor your glucose levels carefully.

Some products listed below consist of two medications combined in the same pill. These are shown with a plus sign (+) between the two medications. Only generic names are used in the following lists. Your pharmacist will be able to tell you the brand names or generic names of medications you use. Due to the aggressive reporting requirements of the FDA, new contraindication information is constantly becoming available. Check with your pharmacist on a regular basis. And remember: If you have any questions about how your medicines can affect your blood sugars, be sure to ask your physician or pharmacist.
