About Glucophage (metformin hydrochloride)
Glucophage, an oral anti-hyperglycemic drug, works by restoring the body's proper response to the insulin you naturally produce. It also decreases the amount of sugar that your liver produces and that your stomach and intestines absorb.
Glucophage is used to treat type 2 diabetes mellitus. Glucophage is available only by prescription. It is available in a generic formulation as well as under different brand names, including metformin hydrochloride.
Glucophage may be prescribed as an oral tablet or oral solution. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.
If you're prescribed Glucophage, be sure to complete the full course of the oral anti-hyperglycemic unless your doctor specifically tells you to stop. If you don’t complete your prescription, the anti-hyperglycemic may not fully treat your type 2 diabetes mellitus.
