Metformin may rarely cause a serious and sometimes fatal condition called lactic acidosis. Most of these cases have occurred in diabetic patients who also have certain kidney problems. The risk of lactic acidosis may be greater if you have liver problems, kidney problems, or heart failure. The risk may also be greater in patients who are elderly or drink alcohol. Lab tests, including kidney function, may be performed while you take Metformin .
Do not begin to take Metformin if you are older than 80 years old unless lab tests show that you do not have decreased kidney function. Do not take it if you have a severe infection, have low blood oxygen levels, or are dehydrated. Tell your doctor you take Metformin before you have any surgery or lab procedures.
Contact your doctor right away if you notice symptoms such as muscle pain or tenderness; unusual drowsiness, dizziness, or lightheadedness; slow or irregular heartbeat; fast or difficult breathing; unusual stomach discomfort; or unusual weakness or tiredness. Contact your doctor right away if you start to feel unusually cold, or if you have a general feeling of being unwell.
Metformin 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.
Metformin 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.
Do NOT use Metformin if:
you are allergic to any ingredient in Metformin
you have congestive heart failure that is treated by medicine
you have a severe infection, low blood oxygen levels, kidney or liver problems, high blood ketone or acid levels (eg, diabetic ketoacidosis), or severe dehydration
you have had a stroke or a recent heart attack, or you are in shock
you are 80 years old or older and have not had a kidney function test
you will be having surgery or certain lab procedures
