Table of contents:

Glumetza is a medication prescribed as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. The active ingriedent in Glumetza is called Metformin Hydrochloride. Metformin belongs to a group of drugs called biguanides. Metformin works by reducing glucose production in the liver, reducing glucose absorption in the intestines, and improving glucose uptake and utilization in peripheral tissues.

Glumetza is an extended-release form of the medication metformin hydrochloride that comes in tablets of 500mg and 1000mg. It can improve glycemic control and can prevent serious complications of diabetes, such as heart attack, stroke, blindness, nerve damage, kidney damage, loss of limbs, and sexual dysfunction. However, Glumetza is not effective in treating type 1 diabetes or diabetic ketoacidosis.

Uses and Dosage

Glumetza is an extended-release tablet that is taken orally. The tablet is typically prescribed once a day, with the evening meal or as directed by your physician. Swallow the tablet whole with plenty of water. Do not crush or chew the tablet as this can release the medicine too quickly, which may increase your chances of experiencing side effects.

Take Glumetza regularly and as prescribed by your doctor, to avoid skipping doses and worsening your condition. Your dosage and frequency are determined by your medical condition, response to therapy, and other medications you are currently taking. Do not change your dosage or stop using Glumetza abruptly without consulting with your healthcare provider.

The typical dosing for Glumetza (Metformin) is usually initiated with 500 mg by mouth twice daily or 850 mg by mouth once daily. Depending on its effectiveness, the total daily dose can be increased up to 2,550 mg per day, split into several doses throughout the day.
