    I had an adverse reaction to this OTC medication. I had taken the proper dose of Allegra D for a couple of days, when serious symptoms started on the third day. I had shortness of breath, and felt completely exhausted. I called my doctor and was told to go to the ER, which I did.

    I couldn't breathe at all through my nose and was prescribed steroids and antibiotics for at least two years leading to tons of side effects. Now I am clear of steroids and antibiotics. I still have a sinus infection but at least I can breathe. This is the only thing that was effective enough to help. Everything else didn't even phase my symptoms. Allegra D 24 hour is amazing.

    I have taken only 2 doses, and can't believe the difference. My head is clear, and the constant sinus ache is gone. But I can't sleep. I'll skip today's afternoon dose, and start again tomorrow morning to see if it makes a difference with my sleeping.

    24 hour version is great. Cost of the drug is overpriced! Packaging is horrible!!!!!!! Why should you need to resort to a sharp implement to get the pill out of the blister???????
