What medications can affect the blood sugar levels of people with diabetes?

People with diabetes often need other medications such as a statin to control cholesterol and blood pressure-lowering drugs. Some drugs can increase your response to insulin; others can reduce it. Those that may increase the blood sugar-lowering effects of insulin include ACE inhibitors, fibrates, certain antidepressants, most oral antidiabetes medications, some anti-arrhythmia drugs, certain pain relievers, hormones and antibiotics.

Drugs that can reduce the blood sugar-lowering effects of insulin include certain steroids; niacin; diuretics; albuterol; certain hormone medications like thyroid hormones, estrogen and progesterones in oral contraceptives; as well as some psychiatric medications such as olanzapine and clozapine.

Beta blockers, clonidine and lithium can make you more susceptible to hypoglycemia (low blood sugar), while pentamidine can cause hypoglycemia sometimes followed by hyperglycemia (high blood sugar).

Remind every healthcare professional who prescribes any drug for you that you take insulin, and ask if the drug will affect your blood sugar levels.
