How to Take Asthma Medications

Asthma medications are dispensed through a variety of delivery methods. With an increasing number of available inhalers, it is most important to know exactly how to use them. When inhalers are not correctly used, less medication gets deep into the airways, making the asthma treatment less effective. Before you or other caregivers use an inhaler for a child, or use one for yourself, you must learn the technique from your health care providers, nurses, pharmacists, or asthma educators. Expect to demonstrate the inhaler technique back, to ensure that you are successfully using the asthma medication.

1.  Inhalers

  • Metered Dose Inhalers (MDI): small device that uses a propellant to produce a spray (or puff) in a measured amount of medication in the lungs. Discharged at a high speed, some of the medication may not reach the lungs and is deposited in the throat. Attaching a spacer/aerochamber allows more time to transport the aerosol to the lungs and improves the delivery of the asthma medication in the lungs.

Pre-filled syringes or Intravenous infusions:  Biologic treatments are indicated for people whose asthma symptoms are not well controlled with the standard combination of quick relief and control medications.  Most biologics are administered in a health provider’s office as a subcutaneous injection or as an intravenous infusion.
