Sanofi-Aventis' prescription non-drowsy antihistamine, Allegra (fexofenadine), has been approved by the U.S. Food and Drug Administration for over-the-counter sale. The drug will be available in its original prescription strengths starting in March for people two years and older, according to a news release from Sanofi and its U.S. consumer division, Chattem Inc. A version that combines Allegra with a decongestant, Allegra-D, will be available at the same time for people 12 and older without a prescription at the pharmacy counter, the companies said.
