Glucophage (metformin) is an oral diabetes medicine that helps control blood sugar levels.
Glucophage is used to improve blood sugar control in people with type 2 diabetes.
Glucophage is sometimes used in combination with insulin or other medications, but metformin is not for treating type 1 diabetes.
Before taking this medicine
You should not use Glucophage if you are allergic to metformin, or if you have:
- severe kidney disease; or
- if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking Glucophage.
To make sure Glucophage is safe for you, tell your doctor if you have:
- kidney disease;
- liver disease;
- a history of heart disease or recent heart attack;
- if you have recently taken chlorpropamide; or
- if you are over 80 years old and have not recently had your kidney function checked.
Some people taking Glucophage develop a serious condition called lactic acidosis. This may be more likely if you have liver or kidney disease, congestive heart failure, a severe infection, if you are dehydrated, or if you drink large amounts of alcohol. Talk with your doctor about your risk.
It is not known whether Glucophage will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medicine.
It is not known whether metformin passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
