Metformin Urged as 1st Drug for Diabetes

Metformin is the best medicine to use first for people with type 2 diabetes, a doctors’ group says. The American College of Physicians issued the new guidelines February 6. The college is a professional group for doctors of internal medicine. The group’s new guidelines say that doctors should first recommend weight loss and regular exercise for people with type 2 diabetes. But if these changes don’t control blood sugar, metformin should be the first drug used, the guidelines say. The doctors’ group found that it lowers blood sugar the most, with the fewest side effects. Doctors should prescribe a second drug if metformin is not enough. But there’s not enough evidence to recommend one specific drug for this second treatment, the guidelines say. Besides its effect on blood sugar, metformin helped to reduce people’s risk of heart disease and early death.
