how to combat diarrhea from metformin
The most common side effect of metformin is diarrhea. Diarrhea caused by metformin will often go away after the first few weeks of therapy, but sometimes it will not. Luckily, there are ways to decrease this side effect. To avoid or minimize diarrhea the dose should start low and be increased slowly by 500mg per week. It may take a month to increase to the correct dose. Starting on a higher dose or increasing the dose too quickly may cause diarrhea. Another alternative is to take the extended release form of metformin.
