Nasal Steroids Mast Cell Inhibitors Ipratropium Bromide Immunotherapy Nasal Steroids Nasal steroids are effective medications to treat allergic rhinitis symptoms.
Nasal steroids are useful for both outdoor and indoor allergies.
Nasal steroids inhibit many parts of the inflammatory response, including both early and late-phase allergic reactions. Nasal steroid sprays are effective when used regularly during the allergic season. Their onset of action may be from hours to days, with the peak effect within days, so they must be taken consistently, not just for acute symptom relief. Corticosteroids have been shown to cause growth suppression in children and teenagers, particularly with higher doses over extended periods. If side effects occur, they are generally mild and may include headache, cough, nosebleeds, or sore throat.
