What should I know about Glumetza (metformin) before taking it?

The most important thing you should know before taking Glumetza (metformin) is that this medication may cause a rare but potentially-fatal medical condition called lactic acidosis. This condition, which is a buildup of an acid in the blood, requires emergency medical attention. Symptoms of lactic acidosis include extreme weakness or fatigue, dizziness, difficulty breathing, stomach pain combined with nausea and vomiting, unusual muscle pain, coldness in your limbs, a slow or irregular heartbeat, or other sudden changes in your medical condition. The risk for lactic acidosis with Glumetza is increased if you have liver, kidney, or heart problems, if you drink a lot of alcohol, or if you get dehydrated. Because of this, it's very important to talk to your doctor about your medical history, including medical conditions and any medications you are taking, since these could increase your risk for lactic acidosis and other side effects.
