Steroid nasal sprays are medicines that are sprayed into the nose, to prevent and treat allergy symptoms of the nose such as stuffy or runny nose, itching, and sneezing. These usually occur with hay fever (also called allergic rhinitis ). Steroid nasal sprays are also used to treat certain growths in the nose called nasal polyps . They work by reducing swelling (inflammation) and mucus in the nose. Because the medicine mainly works in your nostrils, it has very little effect anywhere else in your body. People with hay fever only need to use them for a few months of the year, during the hay fever season, but others may need to use them long-term.
In controlled clinical studies, the types of adverse events observed in patients with nasal polyps were similar to those observed for patients with allergic rhinitis. A total of 594 adult patients (ages 18 to 86 years) received NASONEX Nasal Spray 50 mcg at doses of 200 mcg once or twice daily for up to 4 months for treatment of nasal polyps. The overall incidence of adverse events for patients treated with NASONEX Nasal Spray 50 mcg was comparable to patients with the placebo except for epistaxis, which was 9% for 200 mcg once daily, 13% for 200 mcg twice daily, and 5% for the placebo.
