I have been taking 500mg metformin twice a day for a month now. Will the terrible gas and heartburn go away or should I ask my doctor for a different medication?
A. Heartburn and gas are common side effects with metformin therapy. These side effects are known to last as long as 4-6 weeks. While bothersome, these side effects do not usually require the medication to be stopped. However, that is a decision for you and your physician to make. To avoid/reduce these side effects, it is recommended to start at the lowest dose of metformin and gradually increase toward the optimum dose. Additionally, metformin should be taken with food.
