Metformin Sustained Release Tablets are a biguanide-type medicine used along with a diet and exercise program to control high blood sugar in patients with type 2 diabetes. Metformin Sustained Release 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. Metformin Sustained Release may be used to treat other conditions as determined by your doctor.

Glucophage XR Side Effects:

Metformin Sustained Release side effects include metallic taste in mouth, nausea, vomiting, stomach upset, or diarrhea. If they continue or are bothersome, check with your doctor. If stomach symptoms recur later (after you are on the same dose for several days or weeks), tell your doctor immediately. A late recurrence of stomach symptoms may be due to a serious medical condition called lactic acidosis. CONTACT YOUR DOCTOR IMMEDIATELY if you experience unusual weakness or tiredness, unusual muscle pain, trouble breathing, feeling cold, dizziness, lightheadedness, or a slow or irregular heartbeat.

This medicine usually does not cause low blood sugar (hypoglycemia), but this effect may occur if you do not consume enough calories (from food, juices, fruit, etc.). The symptoms 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, or 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 (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. AN ALLERGIC REACTION to this medicine is unlikely, but seek immediate medical attention if it occurs. Symptoms of an allergic reaction include rash, itching, swelling, dizziness, or trouble breathing. If you notice other effects not listed above, contact your doctor, nurse, or pharmacist.
