How to Treat Allergic Rhinitis

Allergic rhinitis can be caused by pet dander, molds and assorted grasses and allergies. Although seldom serious, the symptoms of allergic rhinitis can be bothersome. Symptoms, which include a runny nose, sneezing, watery eyes and congestion can usually be treated very effectively, and without complication.

• Take an antihistamine. Over-the-counter antihistamines are very effective in treating allergic rhinitis. Although effective in treating symptoms, antihistamines can cause side effects such as dry mouth, drowsiness and urinary retention. Since side effects can be so pronounced, you should not drive or operate machinery when taking antihistamines. Always talk to your doctor before you begin treating allergic rhinitis with antihistamines.


• Visit an allergist. If your allergic rhinitis does not get better with antihistamines, ask your doctor to refer you to an allergist. The allergist may conduct tests such as sensitivity tests that can determine what you are allergic to. In addition, your allergist may recommend allergy shots which may greatly decrease your symptoms. 


• Avoid allergens. When your allergic rhinitis is related to grasses, ragweed, pollen or mold, make sure you close your windows when these counts are high to avoid particles from entering your home.


• Ask about eye drops. Since allergic rhinitis can cause significant eye symptoms such as tearing, itching and burning, ask your doctor about using eye drops. Over-the-counter eye drops may be effective in treating eye symptoms, but your doctor may recommend prescriptions eye drops if your symptoms are severe.


• Consider a decongestant. Most symptoms of allergic rhinitis respond to antihistamines, but sometimes a decongestant is needed for nasal congestion. Decongestants can be purchased over-the-counter, but check with your doctor first, as they can cause a rapid heart rate, insomnia and anxiety.
