Allergy symptoms, especially in late autumn, can get extremely bad. For me, my nose stuffs up and I sound odd, I'm unable to breathe, and my eyes water and itch like nothing else. While allegra-d doesn't quite handle the eye symptoms, or other non-nasal allergy symptoms, the nasal symptoms are handled completely. I am able to breathe again after a single dose, twice daily.
The active ingredient, pseudoephedrine, is unavailable in Oregon over the counter. For those who are forced to choose regular Allegra, it will not suffice. For those who have a prescription from a doctor, the medication is inexpensive, available, and the side effect (like a cup of coffee) is welcome for a lazy summer day. Since I work outside, allergy relief is important to me and Allegra-D is my prescription of choice.
