Glucophage (Metformin)

Glucophage is used for treating type 2 diabetes. It is used along with diet and exercise. It may be used alone or with other antidiabetic medicines.

Use Glucophage as directed by your doctor. Check the label on the medicine for exact dosing instructions.
An extra patient leaflet is available with Glucophage . Talk to your pharmacist if you have questions about this information.
Take Glucophage by mouth with food.
Take Glucophage on a regular schedule to get the most benefit from it. Taking Glucophage at the same time each day will help you remember to take it.
Continue to take Glucophage even if you feel well. Do not miss any doses.

Glucophage is a biguanide antidiabetic. It works by decreasing the amount of sugar that the liver produces and the intestines absorb. It also helps to make your body more sensitive to the insulin that you naturally produce.

If you miss a dose of Glucophage , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Store at room temperature between 20-25 degrees C (68-77 degrees F).
