What Metformin is
Metformin is usually the first medicine used for type 2 diabetes. It lowers blood sugar mainly by making the liver release less sugar and helping the body use insulin better.
What it’s for
Type 2 diabetes. It is also sometimes used for prediabetes and PCOS.
How it’s taken
By mouth, once or twice a day with meals. The dose is usually raised slowly to ease stomach upset.
Good to know
Upset stomach and loose stools are common at first. A rare but serious problem is lactic acidosis (a buildup of acid in the blood), more likely with kidney disease, heavy drinking or severe illness; it is often paused before scans that use contrast dye. Long-term use can lower vitamin B12.
