WARNING: Metformin can rarely cause a condition called lactic acidosis, which can be fatal. Seek immediate medical attention if you develop any of the following symptoms of lactic acidosis: unusual tiredness (fatigue) or severe drowsiness, cold skin, muscle pain, breathing trouble or rapid breathing, unusually slow or irregular heartbeat. Lactic acidosis is more likely to occur in patients who have: kidney or liver disease, conditions that may cause a low oxygen blood level or poor circulation (e.g., severe congestive heart failure, recent heart attack, recent stroke), excessive alcohol use, a lack of body fluids (dehydration), X-ray or scanning procedures that require an injectable iodinated contrast drug, surgery, or a serious infection. Also at higher risk are those who are elderly, especially if you are over 80 years of age and have not had kidney and liver tests.

USES: This medication is a biguanide-type medicine that is used along with a diet and exercise program to control high blood sugar in diabetic patients. This medication works by helping to restore your body's proper response to the insulin you naturally produce, and by decreasing the amount of sugar that your liver makes and that your stomach/intestines absorb. Controlling high blood sugar helps prevent heart disease, strokes, kidney disease, blindness and circulation problems, as well as decreased sexual ability (impotence).

HOW TO USE: This medication is usually taken by mouth, once daily with the evening meal, or as directed by your doctor. This medication must be swallowed whole. Do not crush or chew the tablets. Drink plenty of fluids while taking this medication. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day. Your dosage is based on your medical condition and response to therapy. This medication may come with a Patient Information Leaflet. Read it carefully and ask your doctor or pharmacist any questions you may have about your medication.
