Why is this medication prescribed?
Mometasone nasal spray is used to prevent and relieve symptoms of sneezing, runny, stuffy, or itchy nose caused by hay fever or other allergies. It is also used to treat nasal polyps (swelling of the lining of the nose). Mometasone nasal spray should not be used to treat symptoms (e.g., sneezing, stuffy, runny, itchy nose) caused by the common cold. Mometasone nasal spray is in a class of medications called corticosteroids. It works by blocking the release of certain natural substances that cause allergy symptoms.
How should this medicine be used?
Mometasone comes as a suspension (liquid) to spray in the nose. If you are using mometasone nasal spray to prevent or relieve hay fever or allergy symptoms, it is usually sprayed in each nostril once a day. If you are using mometasone nasal spray to treat nasal polyps, it is usually sprayed in each nostril once or twice daily (in the morning and evening). Use mometasone at around the same times every day.Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use mometasone nasal spray exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
For the prevention of nasal symptoms of seasonal allergies, use mometasone nasal spray 2 to 4 weeks before the beginning of the pollen season.
An adult should help children younger than 12 years old to use mometasone nasal spray. Children younger than 2 years of age should not use this medication.
Mometasone nasal spray is only for use in the nose. Do not swallow the nasal spray and be careful not to spray it into your mouth or eyes.
Each bottle of mometasone nasal spray should only be used by one person. Do not share mometasone nasal spray because this may spread germs.
Mometasone nasal spray controls the symptoms of hay fever or allergies, but does not cure these conditions. Your symptoms may improve in 1 to 2 days after you first use mometasone, but it may take 1 to 2 weeks before you feel the full benefit of mometasone. Mometasone works best when used regularly. Use mometasone on a regular schedule unless your doctor has told you to use it as needed. Call your doctor if your symptoms get worse or do not improve after you use mometasone nasal spray.
Mometasone nasal spray is designed to provide a certain number of sprays. After the marked number of sprays has been used, the remaining sprays in the bottle might not contain the correct amount of medication. You should keep track of the number of sprays you have used and throw away the bottle after you have used the marked number of sprays even if it still contains some liquid.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature, away from direct sunlight, and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website () for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.
What other information should I know?
You should clean your nasal spray applicator periodically. You will need to remove the dust cap and then pull on the applicator to remove it from the bottle. Wash the dust cap and applicator in cold water and rinse them in cold water, let them dry at room temperature, and then put them back on the bottle.
If the spray tip is clogged, wash it in cold water and then rinse it in cold water and dry it. Do not use pins or other sharp objects to remove the blockage.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
