Proper Use

Drug information provided by: Micromedex

Inhaled mometasone is used to prevent asthma attacks. It is not used to relieve an asthma attack that has already started. For relief of an asthma attack that has already started, you should use another medicine. If you do not have another medicine to use for an attack or if you have any questions about this, check with your doctor.

Inhaled mometasone is used with a special inhaler that comes with patient directions. Read the directions carefully before using this medicine. If you do not understand the directions or you are not sure how to use the inhaler, ask your doctor to show you what to do. Also, ask your doctor to check regularly how you use the inhaler to make sure you are using it properly.

Use this medicine only as directed by your doctor. Do not use more of it and do not use it more often than your doctor ordered. Also, do not stop using this medicine without telling your doctor. To do so may increase the chance of side effects.

In order for this medicine to help prevent asthma attacks, it must be used every day in regularly spaced doses and be used at the same time each day, as ordered by your doctor.

To use the Twisthaler®:

  • Take the Twisthaler® out of the pouch before you use it for the first time.
  • Write down the date on the cap label when you first open the foil pouch. The medicine is good for only 45 days once the pouch is opened.
  • The Twisthaler® has a small window on the side with numbers showing. This is the dose counter. It keeps track of how many more times you can use the inhaler before you need to open a new one. When the dose counter reaches "00", the Twisthaler® will lock itself. If the dose counter is not working correctly, do not use the Twisthaler® and return it to your pharmacy or doctor.
  • Remove the cap while it is in upright position to make sure you get the right amount of medicine with each dose.
  • Hold the Twisthaler® upright and twist the cap in a counterclockwise direction to open it. The dose counter should change to a lower number when you take off the cap. The arrow on the Twisthaler® should be pointing to the dose counter.
  • To inhale this medicine, breathe out fully, trying to get as much air out of the lungs as possible. Put the mouthpiece fully into your mouth and close your lips around it. Do not block the mouthpiece with your teeth or tongue.
  • Breathe in through your mouth as deeply as you can until you have taken a full deep breath.
  • Take the Twisthaler® out of your mouth. Hold your breath for about 10 seconds, then breathe out slowly.

  • Wipe the mouthpiece dry with a cloth or tissue. Do not wash it with water. Put the cap back on right away and twist it in a clockwise direction. You should hear a "click" when the cap is fully closed.
  • Gargle and rinse your mouth with water after each dose; this will help prevent hoarseness, throat irritation, and infection in the mouth. Do not swallow the water after rinsing.
