Topical nasal sprays: treatment of allergic rhinitis.

Topical nasal sprays, especially steroids, have regained favor as treatment for allergic rhinitis. Nasal steroids are widely used and are as safe and effective as antihistamines in controlling symptoms of rhinitis. However, if improperly used, steroids can have side effects. It is essential that patients learn correct techniques for administering nasal steroids and understand complications that can result from nasal steroid use. New steroid drugs, such as budesonide, tripedane and fluticasone, are being evaluated and will be available in the near future. Other topical drugs, such as cromolyn and ipratropium, are also effective. Over-the-counter decongestants are helpful in reducing nasal congestion and allowing other topical medicines to penetrate effectively into the nasal cavity, but their use should be limited to no more than three days. Prolonged use of topical nasal decongestants has no place in the treatment of allergic rhinitis and can be associated with significant side effects.
