Glucophage
Tablets
Chemical Name: METFORMIN (met-FOR-min)
Common uses
This medicine is a biguanide-type medicine used along with a diet and exercise program to control high blood sugar in patients with type 2 diabetes. This medicine works by helping 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, circulation problems, and sexual function problems. This medicine may be used to treat other conditions as determined by your doctor.
Before using
WARNING: Metformin may rarely cause a condition called lactic acidosis, which is sometimes fatal. Seek immediate medical attention if you develop any symptoms of lactic acidosis including unusual tiredness, severe drowsiness, cold skin, muscle pain, breathing trouble or rapid breathing, or unusually slow or irregular heartbeat. Lactic acidosis is more likely to occur in patients who have heart failure, kidney or liver problems, excessive alcohol use, a lack of body fluids or dehydration, x-ray or scanning procedures that require an injectable iodinated contrast drug, surgery, a serious infection, heart attack, or stroke. Also at higher risk are the elderly, especially if over 80 years of age and have not had kidney and liver tests. Discuss the benefits and risks of using this medicine with your doctor. Some medicines or medical conditions may interact with this medicine. INFORM YOUR DOCTOR OR PHARMACIST of all prescription and over-the-counter medicine that you are taking. ADDITIONAL MONITORING OF YOUR DOSE OR CONDITION may be needed if you are taking other diabetes medicines such as glyburide or insulin, or cimetidine. Certain medicines may make your diabetes more difficult to control by affecting blood sugar. Report any medicines to your doctor that may affect your blood sugar including, "water pills" (diuretics such as hydrochlorothiazide, furosemide); birth control pills; estrogens; corticosteroids such as prednisone; niacin; phenytoin; decongestants; high blood pressure medicines including beta-blockers such as propranolol; calcium channel blockers such as nifedipine; ACE-Inhibitors such as captopril; phenothiazines such as chlorpromazine; isoniazid; thyroid medicines; clomiphene; fenugreek; or ginseng. USE OF THIS MEDICINE IS NOT RECOMMENDED if you have a history of kidney disease, liver disease, congestive heart failure, heart failure, lactic acidosis, metabolic acidosis, diabetic ketoacidosis, recent heart attack, recent stroke, serious infection, or dehydration. Inform your doctor of any other medical conditions including burns, heart or lung problems, recent trauma, blood problems (anemia, vitamin B-12 deficiency), scheduled upcoming surgery, scheduled upcoming x-ray or scanning procedures, alcohol use, any allergies, pregnancy, or breast-feeding. If you are scheduled to undergo any x-ray or scanning procedure using injectable iodinated contrast material, be sure to inform your doctor that you are taking this medicine. You will need to temporarily stop this medicine around the time of your procedure. Consult your doctor for further instructions.

This medicine usually does not cause low blood sugar, or hypoglycemia, but this effect may occur if you do not consume enough calories from food, juices, fruit, or other sources. The symptoms of hypoglycemia include chills, cold sweat, dizziness, drowsiness, shaking, rapid heartbeat, weakness, headache, fainting, tingling of the hands or feet, or hunger. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you are in a situation where you don't have these reliable forms of glucose, eat a quick source of sugar such as table sugar, honey, candy, or drink a glass of orange juice or non-diet soda to quickly raise your blood sugar level. Tell your doctor immediately about the reaction. To help prevent hypoglycemia, eat meals on a regular schedule and do not skip meals. Symptoms of high blood sugar, or hyperglycemia, include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, or fruity breath odor. If these symptoms occur, tell your doctor immediately. Your medicine dosage may need to be increased. LIMIT ALCOHOL INTAKE while using this medicine.

A late recurrence of stomach symptoms may be due to a serious medical condition called lactic acidosis.
