All generic medications must undergo certain tests that compare them to the original brand-name medications. The U.S. Food and Drug Administration (FDA) then considers the results of these tests to decide if the generic is equivalent to the original brand-name medication and assigns the generic a rating. An "AB" rating means that the FDA has determined that a generic medication is equivalent to the original brand-name medication. All of the generic paroxetine versions currently available have an "AB" rating, meaning they should be equivalent to Paxil.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. These might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
