Generic Allegra

There are several possible side effects that can occur in people taking Allegra (fexofenadine hydrochloride); however, based on data from clinical studies involving over 4,500 adults and children, weight gain does not appear to be one of them.

In clinical studies, side effects are always documented and compared to a control group of people who are not taking the medicine. Side effects are also generally grouped into those that occur in more than 1 percent and those that occur in less than 1 percent (rare side effect) of people. During clinical studies for Allegra, weight gain was not detected as either a common or rare problem.

Generic Allegra is manufactured by a few companies and sold as Fexofenadine Hydrochloride tablets. They are available in the following strengths.

Fexofenadine Hydrochloride tablets 30 mg.
Fexofenadine Hydrochloride tablets 60 mg

At this time, generic Allegra oral suspension (liquid) and generic Allegra ODT (orally disintegrating tablets) are not available.

On Aug. 31, the FDA approved first-time generic formulations of 30, 60, and 180 mg fexofenadine HCl tablets (made by Barr Laboratories, Inc.; brand name Allegra, made by Aventis Pharmaceuticals, Inc.).
