Is Generic Sulfamethoxazole/Trimethoprim as Good as Bactrim?
All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns each generic a rating. An “AB” rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic sulfamethoxazole/trimethoprim versions currently have an “AB” rating, meaning they should be equivalent to Bactrim.
