What is Nasonex?

NASONEX® is the only prescription nasal allergy spray approved for the treatment of seasonal and perennial nasal allergy symptoms in children 2 years of age and older. Taken just once a day, NASONEX® helps relieve an itchy, runny nose; sneezing; and congestion. NASONEX® helps by treating nasal allergy symptoms caused by dust mites, pet dander, even tree and grass pollen. Improvement can occur within 11 hours of initial treatment (based on studies done in a park during the pollen season and in a controlled pollen exposure room). The full benefit of NASONEX® is usually achieved within 1 to 2 weeks. NASONEX® is the only prescription nasal spray clinically proven to prevent most seasonal nasal allergy symptoms in adults and children over 12 years of age. To prevent most seasonal nasal allergy symptoms before they start, begin treatment 2 to 4 weeks before the anticipated start of the pollen season. It is important that you take NASONEX® regularly at the time recommended by your physician, since its effectiveness depends on regular use.

How does it work?

Mometasone is a steroid. It prevents the release of substances in the body that cause inflammation.

• Mometasone is used nasally to prevent and treat the nasal
symptoms of allergies and other seasonal reactions.
• Mometasone nasal may also be used for purposes other than those listed in this medication guide.

How to use Nasonex

Use mometasone nasal spray exactly as directed by your doctor. Read the information insert included with your medication. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.

• Shake the medication well before each dose.
• If your nose is congested, try to clear it before using your medication to be sure that the medicine gets into your nasal passages. If you are also using a decongestant spray, use it to open up your nasal passages before using mometasone nasal. However, do not use a decongestant spray unless your doctor approves.
• Remove the plastic dust cap from the nasal applicator. Prior to initial use of mometasone nasal spray, the pump must be primed by spraying ten times or until a fine spray appears. The pump may be stored unused for up to 1 week without repriming. If unused for more than one week, reprime by pumping two times, or until a fine spray appears.
• Close one nostril and tilt your head slightly forward. Insert the tip of the nasal applicator about 1 cm (one-half inch) into your nostril, pointing it straight up into the nasal canal. Press firmly downward once on the shoulders of the applicator, using your forefinger and middle finger while supporting the base of the bottle with your thumb. Breathe gently inward through the nostril as you pump. Then breathe out through the mouth. Repeat this process for the number of sprays prescribed by your doctor. Remove the pump from your nose. Repeat this procedure in the other nostril then replace the dust cap.
• Do not use more of this medication than prescribed for you. Never use more than 2 sprays in each nostril (200 mcg total) per day. It may take a few weeks to see the effects of mometasone nasal. Talk to your doctor if your symptoms do not improve or if they get worse.
• Do not spray mometasone nasal into the eyes.
• To clean the applicator, remove the plastic dust cap and pull gently on the nasal applicator so that it comes free. Wash the applicator and dust cap with cold water. Dry and replace the applicator and dust cap.
• Store mometasone nasal at room temperature away from moisture and heat. Avoid prolonged exposure of the product to direct light when mometasone nasal is removed from its cardboard container.
