Mometasone is a powder that comes with a special inhaler device preloaded with the medicine. The device will deliver a measured dose of mometasone as a fine spray of powder each time you use the inhaler.

You may or may not be able to feel or taste this powder in your mouth while using the inhaler. Do not use extra doses if you do not feel or taste the powder. Tell your doctor or pharmacist if you think your inhaler is not working properly.

It may take up to 2 weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve after 2 weeks of treatment.

Your dose needs may change if you have surgery, are ill, are under stress, or have recently had an asthma attack. Do not change your medication dose or schedule without your doctor's advice.

If you switched to mometasone from an oral (taken by mouth) steroid, you may need to restart the oral medicine if you are under stress or have an asthma attack or other medical emergency. Wear a medical alert tag or carry an ID card stating that you may need an oral steroid in an emergency.

Store at room temperature away from moisture and heat. When you first open the foil pouch and remove the inhaler device, write the date on the device. Throw away the inhaler after 45 days, or when the dose counter shows "00."
