It is important to replace the cap after each inhalation to protect the inhaler from moisture.

The inhaler has a dose counter on the colored base, which shows the number of doses left to use. As you lift off the cap to take your dose, the dose counter on the base will count down by one (if you began with the dose counter reading "30" this will cause the dose counter to now read "29"). Read the numbers from top to bottom. When the unit reads "01" this indicates the last remaining dose. After dose "01" the counter will read "00". When you replace the cap, the unit will lock and then must be thrown away. Start using a new Asmanex Twisthaler as instructed by your health care provider.
