Some asthma medications can be taken in the form of a dry powder using a small, hand-held device called a dry powder inhaler (DPI). Dry powder inhalers deliver
medication to the lungs as you inhale through the device. The DPI does not
contain propellants or any other ingredients. It contains only the medication.
The Twisthaler (figure 1 to the right) contains the inhaled corticosteroid mometasone (Asmanex®),
which comes in 2 strengths—110 mcg (grey) and 220 mcg (pink).
When you get a new Twisthaler, remove it from the foil pouch and write the date on the cap. The Twisthaler will need to be thrown out
45 days after this date or when the dose counter reads "00" (see figure 3
"Caring for your Twisthaler DPI").
Preparing the Twisthaler
1. While holding the Twisthaler upright, twist the white cap counter clockwise.
2. As you twist and lift off the cap, the dose counter will decrease by one and the medicine is now ready to be inhaled.
Inhaling the medication
3. While holding the Twisthaler away from the mouth, gently blow out all the air from your lungs.
4. Hold the Twisthaler horizontally and place the mouthpiece between your teeth sealing your lips tightly around the mouthpiece. (figure 2
to right)
5. Breathe in rapidly and as deeply as you can.
6. Hold your breath for 10 seconds.
7. Replace the cap and twist clockwise. Make sure it clicks to completely close it. (This must be done to properly load the next dose).
8. Repeat steps 3 through 7 for each dose ordered.
9. Rinse your mouth and gargle (do not swallow) after each treatment as this is corticosteroid medicine.
Caring for your Twisthaler DPI
- Keep your dry powder inhaler in a dry place at room temperature.
- Never place the DPI in water.
- Never shake or breathe into the DPI.
- Never use a spacer device with your DPI.
The Twisthaler has a dose counter (figure 3
at right) that automatically counts down the dose when the cap is removed. This action also loads the
dose of medication. When the counter reads "00" there is no medicine left in the Twisthaler.
Unlike other inhaled medications, you may not taste or feel the dry powder or there may be a slight sweet taste. This experience may be
different from what you are used to. As long as you are following the directions, you will get your full dose of medication.
