How does the dose counter function on the Asmanex device?

The dose counter on the Asmanex device functions by counting down each time the cover is removed. When the device is used, the counter decreases to indicate the number of remaining doses available. This design allows patients to easily monitor their dosage and know how many doses are left, thereby aiding in medication adherence and planning for refills. This system is intuitive and helps prevent running out of the medication unexpectedly, contributing to better asthma management. The other options do not accurately describe the operational mechanism of the dose counter for the Asmanex device.
