For mild or intermittent environmental allergies, an antihistamine is typically sufficient.
This includes claritin, zyrtec, and allegra. For more significant or persistent hayfever, a prescription nasal spray is more effective. These include flonase, qnasl, nasonex, (mometasone) etc. The best approach is to see an allergist to help in identifying allergen, employing avoidance measures first.
