How Supplied


GLUMETZA is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Important Limitations Of Use

GLUMETZA should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis, as it would not be effective in these settings.


Recommended Dosing

GLUMETZA should be taken once daily with the evening meal. The dosage of GLUMETZA must be individualized on the basis of both effectiveness and tolerability, while not exceeding the maximum recommended daily dose of 2000 mg. The starting dose of GLUMETZA in patients who are not currently taking metformin is 500 mg once daily, with the evening meal. The dose can be uptitrated in 500 mg increments no sooner than every 1-2 weeks if a higher dose of GLUMETZA is needed and there are no gastrointestinal adverse reactions.

If GLUMETZA is considered appropriate for a patient already receiving immediate-release metformin, the patient can be switched to GLUMETZA once daily at the same total daily dose, up to 2000 mg once daily.

GLUMETZA tablets must be swallowed whole and never split, crushed or chewed. Occasionally, the inactive ingredients of GLUMETZA 500 mg may be eliminated in the feces as a soft, hydrated mass, while the 1000 mg may leave an insoluble shell that may resemble the original tablet. If a dose of GLUMETZA is missed, patients should be cautioned against taking two doses of 2000 mg the same day. Resume dosing as according to prescribing recommendations. (See PATIENT INFORMATION)

Co-administration of GLUMETZA with an insulin secretagogue (e.g., sulfonylurea) or insulin may require lower doses of the insulin secretagogue or insulin to reduce the risk of hypoglycemia
