Mometasone is used to prevent and treat seasonal and year-round allergy symptoms (such as stuffy/runny nose, itching, and sneezing). It is also used to treat certain growths in the nose (nasal polyps). Mometasone belongs to a class of drugs known as corticosteroids. It works by reducing swelling (inflammation) in the nasal passages.
How to use Nasonex Aerosol, Spray With Pump
Use this medication in the nose as directed by your doctor, usually once a day for runny nose (rhinitis) and once or twice a day for polyps. Do not spray in the eyes or mouth. Gently blow your nose before using this drug. Shake the container well before each use. Follow the instructions to properly prime the spray pump.
To use the spray, remove the protective cap. Close one nostril by pressing it with your finger. Tilt your head slightly forward and, keeping the bottle upright, carefully insert the nasal applicator into the other nostril. Press down firmly on the pump to deliver the prescribed number of sprays. Do not spray directly onto the middle wall of your nose (nasal septum). Breathe in gently through your nose and out through your mouth. Repeat in the other nostril. Wipe the applicator tip and replace the plastic cap. Avoid blowing your nose for 15 minutes after using this medication.
Dosage is based on your medical condition and response to treatment. Younger children may need a smaller dose and help from an adult to use this medication properly. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. Do not increase your dose or use it more frequently than directed.
This medication does not work right away. Some people will feel this medication working within 2 days, but it may take up to 2 weeks before the full benefit of this drug takes effect. When using mometasone to prevent seasonal allergy symptoms, you may need to start this medication 2-4 weeks before pollen season begins. Ask your doctor or pharmacist if you should also use other medications (such as nose drops/spray, allergy drugs taken by mouth) along with this drug until it takes full effect.
Keep track of the number of sprays used from the container. Discard the container after you have used the number of sprays specified on the manufacturer's package. Follow the package instructions to unblock the spray tip if needed and to clean the spray bottle.
Tell your doctor if your symptoms do not improve after 2 weeks or if they worsen.
