Pollen allergic reaction, what to do?

Keep pollens away. Eliminate exposure by using facial mask, high efficient hepa filter and vacuum your carpet more often. Use AC at home and when you drive in bad allergy season. Besides, there are OTC oral antihistamines, decongestants, and inhalers available. If not improve, talk to your doctor or allergy specialist for more potent treatments including nasal antihistamines, steroid inhaler and immuno-therapy.
