A nasal corticosteroid spray reduces swelling and mucus in the nasal passageway. It also relieves bothersome nasal symptoms. The sprays work well for treating:
- Allergic rhinitis symptoms, such as congestion, runny nose, sneezing, itching, or swelling of the nasal passageway
- Nasal polyps, which are noncancerous (benign) growths in the lining of the nasal passage
A nasal corticosteroid spray is different from sprays you can buy at the store without a prescription.
A corticosteroid spray works best when used every day without stopping. Your doctor will recommend a daily schedule of the number of sprays for each nostril.
You may also use the spray on an as-needed basis only, or as needed along with regular use. Regular use gives you better results.
It may take two weeks or more for your symptoms to improve. Be patient. Relieving the symptoms can help you feel and sleep better and have fewer symptoms during the day.
Starting a corticosteroid spray at the beginning of pollen season will give you the best results in terms of decreasing symptoms during that season.
Several brands of nasal corticosteroid spray are available. They all have similar effects.
