What should I know before my child uses Glucophage?

Before your child begins using the diabetes drug Glucophage (metformin), you should know that clinical studies have shown it to be safe and effective in children ages 10 and older.

Glucophage can cause side effects, including diarrhea, nausea, upset stomach and a metallic taste in the mouth. Let your child's doctor know if any side effects are bothersome or don't go away.

This drug can cause low blood sugar if your child doesn't eat enough, takes other blood sugar-lowering medications or drinks alcohol. To make sure the drug is working properly, monitor your child's blood sugar levels according to her doctor's instructions.

Before your child begins Glucophage, be sure to talk with her doctor about all the medications (prescription and nonprescription), supplements and herbal remedies your child takes. Also tell the doctor about any medical conditions your child may have, especially kidney, liver or heart disease. People with reduced kidney function are at increased risk of developing a serious side effect called lactic acidosis. Call the doctor right away if your child experiences any of the following symptoms while taking Glucophage:

• feeling weak, tired or uncomfortable
• unusual muscle pain
• problems breathing
• increased sleepiness
• unexplained stomach discomfort
• feeling cold, dizzy or light-headed
• sudden onset of a slow or irregular heartbeat
