About this Medication

What the Medication Is Used For

NASONEX is a corticosteroid, which reduces inflammation. It was prescribed to you by your doctor to treat the symptoms of one of the following conditions:

In adults, adolescents and children between the ages of 3 and 11 years

Seasonal allergic rhinitis: also called «hay fever» is caused by allergies to grass, pollen, ragweed, etc. Symptoms include stuffiness/congestion in the nose, runny nose, itching and sneezing.

Perennial allergic rhinitis: year round allergies caused by dust mites, animal dander and molds. Symptoms include stuffiness/congestion in the nose, runny nose, itching and sneezing.

In adults and children 12 years of age or older

Adjunctive treatment to antibiotics in acute episodes of rhinosinusitis, where signs or symptoms of bacterial infection are present: acute rhinosinusitis is the inflammation of the nasal sinuses that may be complicated with a bacterial infection. NASONEX is used for the treatment of the inflammatory component and the antibiotic is used for the infection of the nasal sinuses. Symptoms include (but are not limited to) stuffiness/congestion in the nose, runny nose, feeling of something running down the back of the throat, fever, severe facial/tooth pain (especially on one side of the face), facial swelling or thick nasal discharge with a yellow or green colour.

Mild to moderate uncomplicated acute rhinosinusitis, where signs or symptoms of bacterial infection are not present: NASONEX is used for the treatment of symptoms related to the inflammation and blockage of the sinuses behind the nose. Symptoms include stuffiness/congestion in the nose, runny nose, feeling of something running down the back of the throat, and facial pressure or pain. If symptoms get worse or you start to have fever, persistent severe facial/tooth pain (especially on one side of the face), facial swelling or thick nasal discharge with a yellow or green colour, consult your physician immediately.

In adults 18 years of age or older

Nasal polyps: small growths on the lining of the nose that usually affect both nostrils. The main symptom is a blocked feeling in the nose which may affect breathing through the nose. Other symptoms may include watery nose, a feeling of something running down the back of the throat, loss of taste and smell.

What It Does

When sprayed into the nose it helps reduce symptoms of the conditions listed above.

  • if your nose was recently operated on or injured. In this case you may be told to wait until healing has occurred before using NASONEX.
  • if you have been diagnosed with tuberculosis and it is not being treated.
  • if you have untreated fungal, bacterial, or systemic viral infections.
  • if you have a herpes simplex (virus) infection of the eye and it is not being treated.

Directions for Use

DO NOT SPRAY INTO THE EYES. FOR INTRANASAL USE ONLY.

Read complete instructions carefully and use only as directed.

SHAKE WELL BEFORE EACH USE.

  1. Remove the teal-blue plastic dust cap.
  2. The very first time the spray is used; prime the pump by pressing downward on the shoulders of the white applicator, using your forefinger and middle finger while supporting the base of the bottle with your thumb. Do not pierce the nasal applicator. Press down and release the pump 10 times or until a fine spray appears. The pump is now ready to use. The pump may be stored unused for up to 2 weeks without repriming. If unused for more than 2 weeks, prime the pump again two (2) times, until a fine spray appears.
  3. Gently blow your nose to clear your nostrils. Close one nostril using your finger. Tilt your head forward slightly and, keeping the bottle upright, carefully insert the nasal applicator into the other nostril.
  4. For each spray, press firmly downward once on the shoulder of the white applicator, using your forefinger and middle finger while supporting the base of the bottle with your thumb. Spray while breathing gently inward through the nostril, with the mouth closed.
  5. Then breathe out through your mouth.
  6. Repeat in the other nostril.
  7. Replace the plastic dust cap after each use.

The correct amount of medication in each spray can only be assured up to 140 sprays from the bottle even though the bottle may not be completely empty. You should keep track of the number of sprays used from each bottle of NASONEX, and discard the bottle after using 140 sprays (approximately five weeks of supply, depending on the prescribed dose). If you have a sample size bottle, it contains 40 sprays.

Cleaning: To clean the nasal applicator, remove the plastic dust cap and pull gently upward on the white nasal applicator so that it comes free. Wash the applicator and dust cap under a coldwater tap.Do not try to unblock the nasal applicator by inserting a pin or other sharp object as this will damage the applicator and cause you not to get the right dose of medicine.Dry and replace the nasal applicator followed by the plastic dust cap.

Re-prime the pump with two (2) sprays when first used after cleaning.
