What is metformin?
Metformin is an oral diabetes medicine that helps control blood sugar levels.

Metformin is for people with type 2 (non-insulin-dependent) diabetes. Metformin is sometimes used in combination with insulin or other medications, but it is not for treating type 1 diabetes.

Metformin may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about metformin?
Do not use metformin if you have kidney disease, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
Before taking metformin, tell your doctor if you have liver disease or a history of heart disease.

Some people have developed a life-threatening condition called lactic acidosis while taking metformin. Get emergency medical help if you have any of these symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, stomach pain, feeling light-headed, and fainting.
If you need to have any type of x-ray or CT scan using a dye that is injected into a vein, you may need to temporarily stop taking metformin. Be sure the doctor knows ahead of time that you are using this medication.

Know the signs of low blood sugar (hypoglycemia) and how to recognize them, including hunger, headache, confusion, irritability, drowsiness, weakness, dizziness, tremors, sweating, fast heartbeat, seizure (convulsions), fainting, or coma (severe hypoglycemia can be fatal). Always keep a source of sugar available in case you have symptoms of low blood sugar.

What should I discuss with my healthcare provider before taking metformin?
Some people have developed a life-threatening condition called lactic acidosis while taking metformin. Get emergency medical help if you have any of these symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, stomach pain, feeling light-headed, and fainting.
You may be more likely to develop lactic acidosis if you have congestive heart failure. Older adults may also have a higher risk of developing lactic acidosis. Talk with your doctor about your individual risk.

Do not use this medication if you are allergic to metformin, if you have kidney disease or kidney failure, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).

a history of heart disease.

If you have any of these conditions, you may need a dose adjustment or special tests to safely take metformin.
