Beclomethasone nasal spray belongs to a class of medications called corticosteroids. It is used to treat seasonal allergic rhinitis and perennial (year-round) allergic rhinitis.

This medication works by reducing swelling and inflammation in the nasal passages and relieves symptoms of allergic rhinitis (e.g., runny nose, stuffy nose). You should experience some improvement in your symptoms a few days after starting the medication, but it may take as long as 2 weeks to see the full effect of the medication.

Beclomethasone diproprionate nasal spray is also used to treat nasal polyps, to prevent their return after surgery, or to prevent their increase in size.

Use beclomethasone nasal spray exactly as prescribed by your doctor. To be effective, it must be used regularly.

To use the spray:

• Tilt your head forward slightly, then insert the nozzle of the spray into one nostril and close the other nostril with your finger.
• Press down on the nozzle once while breathing in through the nose and keeping your mouth closed.
• Exhale through your mouth.

Repeat the same procedure with the other nostril. Use your right hand to spray the left nostril and the left hand to spray the right nostril. Then repeat the entire process for each nostril for the second application. Try to aim the first spray high into the nose and the second one into the lower half of the nose.
