Do generic drugs work as well as brand name drugs?
Yes. A generic drug is the same as a brand name drug in safety, strength, quality, the way it works, dose, the way it is taken, and the way it should be used. This is required by the U.S. Food and Drug Administration (FDA).
You should know that not all brand name drugs are available as generic versions. Also, because some medicines (such as Warfarin, Coumadin, Premarin, Dilantin, and certain thyroid drugs) are very sensitive, your doctor may recommend using a brand name medicine to make sure you stay healthy.
