FAQ

A: Yes, in the United States and most countries, Metformin is a prescription-only medication. A healthcare provider must assess your condition and determine the correct dosage.
Q: Is generic Metformin as effective as the brand name?
A: Yes. The FDA requires generic drugs to have the same active ingredient, strength, dosage form, and route of administration as the brand-name drug. They are bioequivalent and clinically interchangeable for the vast majority of patients.
