Nasal corticosteroid sprays help to reduce swelling and mucus in the nasal passageway and relieve other bothersome nasal symptoms. The sprays work well:
- For people with allergic rhinitis symptoms, such as congestion, runny nose, sneezing, itching, or swelling of the nasal passageway
- To treat nasal polyps (benign growths in the lining of the nasal passage)
Nasal corticosteroid sprays are different from the sprays you can buy at the store without a prescription. They work best when used every day without stopping. Your doctor will recommend a daily schedule of sprays for each nostril.
It may take two weeks or more for your symptoms to improve the most. Be patient. Relieving the symptoms can help you or your child to feel and sleep better and have fewer symptoms during the day.
You may also use them on an as-needed basis only, or as-needed along with regular use. Regular use, however, will typically give you better benefit.
Starting nasal corticosteroids at the beginning of a pollen season will give you the best results in decreasing symptoms during that season.
Several brands of nasal corticosteroids are available, such as Flonase or Nasonex. They all have very similar effects.
