What Does Patent Expiry Mean for Phentermine?

Generic versions of phentermine are bioequivalent to their brand-name counterparts, meaning they contain the same active ingredient, dosage form, strength, and route of administration. The U.S. Food and Drug Administration (FDA) requires generic drugs to meet the same standards of quality and efficacy as brand-name drugs. While the inactive ingredients may differ, this typically does not affect the drug's performance in the body.
