Allergic Rhinitis
"I find Fexofenadine HCL very effective against my allergies which seem to be a year-round problem, but I have also found it gives me a headache which doesn&#039;t go away with your average OTC medicines.  I tried my mother&#039;s prescription, same dosage, different manufacturer, and no headache (weird) so I may have my Doctor to give me some but otherwise it&#039;s GREAT!"
