These include steroid sprays like Nasonex (mometasone) (and others) and antihistamine sprays like astelin. Claritin, zyrtec, and Allegra (and their generics) don't cross the blood brain barrier very well, so cause very little sedation. Some people who are very sensitive may still have some drowsiness however. Try nasal washes with a neti pot for a no-drug treatment.
