What is mometasone inhalation (Asmanex Twisthaler)?

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

Mometasone inhalation is used to prevent asthma attacks. It will not treat an asthma attack that has already begun.

Mometasone may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about mometasone inhalation (Asmanex Twisthaler)?

Do not use mometasone inhalation to treat an asthma attack that has already begun. It will not work fast enough to reverse your symptoms. Use another, faster-acting inhalation medication to treat an asthma attack.

Seek medical attention if you think any of your asthma medications are not working as well as usual. An increased need for medication could be an early sign of a serious asthma attack.

It may take up to 2 weeks of using this medicine before your symptoms improve. For best results, keep using the medication as directed. Talk with your doctor if your symptoms do not improve after 2 weeks of treatment.

Your dosage needs may change if you have surgery, are ill, are under stress, or have recently had an asthma attack. Talk with your doctor if any of your asthma medications do not seem to work as well in treating or preventing asthma attacks.

If you were switched from an oral (taken by mouth) steroid to mometasone inhalation, you may need to go back to taking the oral medicine if you are under stress or have an asthma attack or other medical emergency. Carry an identification card or wear a medical alert ID to let others know that you may need an oral steroid in an emergency.
