HOW NASAL CORTICOSTEROIDS HELP ALLEVIATE ALLERGY SYMPTOMS

Corticosteroid nasal sprays, also called steroid nasal sprays, are used to alleviate the symptoms of seasonal allergies, sinusitis, and nasal polyps (noncancerous growths inside the nose). They are available over-the-counter or as a prescription from a doctor. They work by mimicking the effects of the hormones produced by the adrenal glands. When sprayed into the nose, they reduce inflammation, causing the symptoms of an allergic reaction. Nasal corticosteroids are different from other types of nasal sprays that are used to reduce cold symptoms. Research shows that corticosteroid nasal sprays work best when they are used on a daily basis; however, they may also be used as needed, depending on your doctor’s recommendation.

P.S. If you regularly experience seasonal allergies, your doctor may recommend that you start taking a nasal corticosteroid one to two weeks before you normally start experiencing symptoms.
