Rx Authorized generic Not listed now
An authorized generic of Allegra-D 12 Hour has been sold in the past, but none is listed with the FDA right now. It may have been discontinued.
Ask your pharmacist whether a regular generic (fexofenadine hydrochloride and pseudoephedrine hydrochloride) is available. Generics usually cost much less than the brand.
