Metformin Drug Interactions

Metformin drug interactions with other medications (such as certain decongestants, calcium channel blockers, and diuretics) can potentially lead to problems. Some of these drug interactions can make metformin less effective, increasing your chance of high blood sugar, or can increase the level of metformin in your blood, increasing your risk of side effects. Therefore, be sure to talk to your healthcare provider about any metformin drug interactions that may apply to you.
