Metformin oral tablet is available as both a generic and brand-name drug. Metformin is used to treat high blood sugar levels caused by type 2 diabetes. It works along with diet and exercise. Metformin works by helping to restore your body’s proper response to the insulin you naturally produce. It also decreases the amount of sugar that your liver makes and that your stomach/intestines absorb.

Diarrhea, nausea, stomach pain, heartburn, gas, tiredness, weakness, unusual muscle pain, dizziness are some common side effects of metformin.
