allergies
"I normally take Allegra and Flonase for my allergies. However, when I have breakthrough allergic symptoms, all I have to do is take a small dose of hydroxyzine (10 mg) and I feel significantly better within half an hour. Granted, it does make me feel somewhat sedated. However, that's pretty much a given for all first generation antihistamines. Furthermore, it makes me feel less out of it than Benadryl does. And, unlike Benadryl, hydroxyzine doesn't make my asthma worse; it actually improves my lung function!



It does make me feel sleepy for at least 8 hours, but my allergies make me feel sleepy anyway, so this side effect doesn't really matter."
