Fexofenadine / pseudoephedrine
"I have chronic rhinitis. I was very ill last year, and my immune system hasn't been the same since. My immune system now reacts to everything around me, i.e. I'm allergic to all of my surroundings: dust, pollen, etc. Instead of the typical runny nose and sneezing, the inner membrane of my nose would swell almost completely shut. I was miserable. Accompanied by a nasal spray, Allegra D was the best thing that's ever been prescribed to me! Although at first I suffered severe insomnia, the side-effects became milder with time."
