Interactions between your drugs


metFORMIN colesevelam

Applies to: metformin and colesevelam

Colesevelam may increase the blood levels and effects of metFORMIN. You may need a dose adjustment or closer monitoring of your blood sugar to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects such as nausea, vomiting, diarrhea, flatulence, and indigestion. You should seek immediate medical attention if you develop weakness, muscle pain, chills, increasing drowsiness, abdominal pain or discomfort, slow or irregular heartbeat, breathing difficulty and other unusual symptoms, as these may be early signs of a rare but serious side effect of metFORMIN known as lactic acidosis. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
