I was just diagnosed with diabetes. Last week my doctor prescribed metformin to me. I take one 500mg pill two times a day. I have been having diarrhea about 2 hours after each dose. Is this normal and will it go away? I, also, take lisinopril for blood pressure and a baby aspirin for heart protection.

The most common side-effects of Metformin are feeling sick, diarrhea and abdominal pain. These symptoms do not usually last long.
If the side effects do not settle or become bothersome talk with your doctor.
Your dose may need to be reduced to allow your body to adjust.
Your doctor may consider switching you to an slow-release medication which may reduce diarrhea, because smaller amounts are absorbed over the day rather than hitting your system all at once.
Make sure you take metformin just after a meal or with a snack.

Yes it will stop, in one to two weeks after taking them. Your body has to adjust to ur mets. I did the same, metformins have different side affects, and thats the one ur body chose, as well as mines. It will stop, but when ever u go periods of time without taking ur meds u will go through the side affects each time u start them over.

I've taken Metformin for years and have battled diarrhea for years from it. What works best for me is Metamucil. I take 4 teaspoons a day. Something about the added fiber stops the diarrhea, for me anyway. Start out slowly (1 teaspoon a day) and build up. Too much fiber too quickly can cause stomach / abdominal pain.
Always take the Metformin right after a meal. A meal, not a snack. 50 -100 calories + a Metformin = diarrhea.
