Maximum adult dose of metformin is 2500 mg per day if there are no serious complications of diabetes.
Mr. lybrate-user I do not give metformin more then 1500gm per day.
2000 mg per day is permissible.
Hello, thanks for the query. Usually maximum recommended dose of metformin per day is 2500 mg. Most often 2000 mg is given in most patients. Thanks.
