Mometasone Inhaler Dosing

If you are preventing asthma attacks with a mometasone inhaler, dosing usually starts at 220 mcg (one inhalation) once daily in the evening (if you are also taking other inhaled asthma medications). Your healthcare provider may increase this dosage up to a maximum of 440 mcg (two inhalations) once daily in the evening, or 220 mcg (one inhalation) twice daily. For people who are also taking oral steroids, the starting dose (and maximum dose) of the mometasone inhaler is 440 mcg (two inhalations) twice daily.

 

An Introduction to Mometasone Inhaler Dosing

The dose of the mometasone inhaler (Asmanex®) your healthcare provider recommends will vary depending on a number of factors, including:
 
  • The severity of your asthma
  • Other medications you may be taking.
     
As always, do not adjust your dose of the mometasone inhaler unless your healthcare provider specifically instructs you to do so.
 
Mometasone Inhaler Dosing for Asthma
For asthma treatment in adults and adolescents who are at least 12 years old, the recommended mometasone inhaler dose varies depending on what type of asthma medication a person has been previously taking.
 
For people taking only inhaled asthma medications, the starting dose of the mometasone inhaler is 220 mcg (one inhalation) once daily in the evening, and the maximum dose is 440 mcg (two inhalations) once daily in the evening or 220 mcg (one inhalation) twice daily.
 
For people taking oral steroids (such as prednisone), the starting dose (and maximum dose) of the mometasone inhaler is 440 mcg (two inhalations) twice daily.
 

General Mometasone Inhaler Dosing Information

Following are some considerations for people taking the mometasone inhaler:
 
  • The mometasone inhaler comes in a special inhaler called the Twisthaler®.
     
  • The mometasone inhaler is taken once or twice a day every day. It is used to prevent asthma attacks, not to treat them.
     
  • The Twisthaler works differently from other inhalers. It contains a dry powder that is inhaled using the force of your breath. You may not be able to taste or feel the powdered medication.
     
  • It is important to learn exactly how to use your mometasone inhaler. It may be difficult at first and may require some practice.
     
  • Rinse your mouth (without swallowing) after each dose of the mometasone inhaler in order to prevent thrush.
     
  • The Twisthaler must be discarded 45 days after it is removed from the foil packaging, or when the dose counter reads "00" (meaning there are no more doses left in the inhaler).
     
  • For the mometasone inhaler to work properly, it must be taken as prescribed. The mometasone inhaler will not work if you stop taking it.
     
  • If you are unsure about anything related to your dosage or mometasone inhaler dosing in general, please talk with your doctor, nurse, or pharmacist.
