What are some side effects of Glucophage?
Glucophage® (metformin) is a
medicine used with diet and exercise to help reduce blood sugar levels in people with type 2
diabetes (adult onset). It may also be used to treat polycystic ovary syndrome, a hormonal
condition in women. The most common side effects of Glucophage® are nausea and vomiting,
diarrhea, gas, headache, dizziness, metallic taste and fatigue. These side effects usually
diminish after people have taken Glucophage® for a few weeks. The most serious side effect
associated with Glucophage® is a condition called lactic acidosis -a rare but dangerous
condition that is mainly a risk for patients who also have kidney problems.
Potential serious side effects
You should not use Glucophage® if
you have kidney or liver problems. Signs of lactic acidosis include general body discomfort,
muscle pain, difficulty breathing, stomach pain, chills, lightheadedness, or slow heartbeat.
Contact your doctor if you have any of these symptoms. Surgery may also increase the side
effects of Glucophage®. Most patients should stop taking the medicine prior to surgery, and not
restart it until they're eating and drinking normally again. Ask your doctor for specific
instructions about Glucophage® if you are planning to have surgery.
