Dry powder inhalers DPIs deliver medication without using chemical propellants, but they require a strong and fast inhalation. No matter which you use, getting the medication to your lower airways is essential for the medication to work. For all devices, education and training on how to correctly use them is very important. A device called a spacer may be prescribed if you're having trouble getting the medicine to your airways with an MDI. Spacers help you coordinate your inhaled breath with the release of the medication from the MDI canister.
How often do you need to take your non-steroidal inhaler? Non-steroidal inhalers need to be taken regularly every day for them to have an effect on the inflammation. However, they need to be taken more often than medication based preventers - up to three or four times a day on a regular basis. If you've been prescribed a non-steroidal inhaler, your GP or asthma nurse will tell you how often you need to take it. With any asthma preventer medicine, it's very important to get into a good routine of taking it as prescribed and discussed with your GP or asthma nurse.
