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.

I have severe pollen allergies and Allegra D was the best medicine I ever took, until I could not sleep. It causes insomnia in me so the trade off is insomnia versus feeling miserable 24/7.
It took 2-3 days before I first received relief. Then there was a huge difference.

I used to take an allergy drug called Ornade some years ago. It provided me instant relief of my allergy symptoms (hayfever and ragweed-related). Since then the only allergy medication that gives me that kind of relief is Allegra-D.

My spouse recently began taking Allegra-D for seasonal allergies,has been taking it for more than one week, but no sign of relief. Surprisingly he passed a tablet in his stool! Why would this occur?
