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.
