Glucophage is an oral antidiabetic medication used to treat type 2 (non-insulin-dependent) diabetes. Diabetes develops when the body proves unable to burn sugar and the unused sugar builds up in the bloodstream. Glucophage lowers the amount of sugar in your blood by decreasing sugar production and absorption and helping your body respond better to its own insulin which promotes the burning of sugar. It does not however increase the body’s production of insulin.

Glucophage is sometimes prescribed along with insulin or certain other oral antidiabetic drugs such as Micronase or Glucotrol. It is also used alone.

Standard Glucophage tablets are taken two or three times daily.

Your doctor will tailor your dosage to your individual needs.

Glucophage may rarely cause a serious condition called lactic acidosis. Tell your doctor if you have or have ever had kidney or liver disease heart failure treated by medication or sepsis.

If you have a radiologic procedure and are injected with contrast materials (urogram cholangiography angiography CT scan) tell the doctor that you are taking metformin.
