this a great question that you can always ask your pharmacist. yes these are common side effects from the medication. it is very important that you drink a lot of fluids so you do not become dehydrated. are you taking the medication with food? this may help alleviate the gas and bloating. i would also recommend mentioning this to your health care provider on your next visit. they may adjust the dose of your medication.
i’ve taken metformin for my diabetes for two years. i now have loose stool bloating and gas. is this a side effect?
