There are various types of devices used to deliver inhaled medications. They are divided into two categories:
While the devices must be prepared in different ways, once they are ready for use, the inhalation technique itself is similar for all the devices:
If you need to take two doses of a medication, wait approximately one minute between puffs.
Many devices have an indicator or dose counter that shows the number of puffs they contain, which is convenient as it shows when you will need to renew them. However, some metered-dose inhalers used as quick-relief medication do not. In this case, it is crucial to keep track of the doses you take so you don’t find yourself in an emergency situation with an empty inhaler. You can keep track of the doses using a logbook or an app on your smartphone. Some people stick a piece of tape on their device and draw a line on it each time they take a dose. It doesn’t matter which method you choose, so long as you use one!
An inhaler device that is used improperly can lead to sub-optimal treatment. If you are having trouble using your device, be sure to talk to your pharmacist. Have your pharmacist check your technique at least once a year. He or she can give you pointers, as needed.
