What Is ProAir HFA?

ProAir HFA (albuterol) is used to prevent and treat wheezing, shortness of breath, coughing, and chest tightness caused by breathing problems that may be associated with certain lung diseases. It’s a quick-relief medication and a beta-agonist. It works by relaxing the airway muscles to open air passages to the lungs to make breathing easier. Albuterol also inhibits the release of immediate hypersensitivity mediators from mast cells.

ProAir is available in three different types of ProAir inhalers:

  • ProAir HFA: metered-dose inhaler that releases the drug as a fine mist
  • ProAir RespiClick: a dry powder inhaler that releases the drug as a powder
  • ProAir Digihaler: a dry powder inhaler that connects the inhaler to a mobile app on your phone to tell you how well you’re inhaling the medication

All three forms of ProAir inhalers come in a strength of 90 micrograms (mcg) per puff. It’s a prescription drug and must be used as prescribed by your healthcare provider.

How to Take ProAir HFA

Follow the instructions on your prescription label and use the medicine exactly as directed.

  1. Remove the protective cap from the mouthpiece and ensure that the canister is inserted into the mouthpiece properly.
  2. If you’re using a new inhaler or have not used it in more than 14 days, prime it. Shake it well and press to release four sprays into the air, away from your face. Avoid contact with your eyes. 
  3. Breathe out through your mouth. Hold the canister to place the open end of the mouthpiece in your mouth and close your lips.
  4. Breathe in through the mouthpiece and press down on the container to spray the medication into your mouth.
  5. Hold your breath for about 10 seconds or as long as you comfortably can; remove the inhaler, and breathe out slowly.
  6. If you are prescribed to have two puffs, wait for one to five minutes and then repeat to inhale.
  7. Replace the protective cap on the inhaler. Keep your inhaler clean.

Other directions to keep in mind:

  • Help a young child use ProAir HFA.
  • Take your puffs 15 to 30 minutes before exercising to prevent exercise-induced bronchospasm. 
  • Shake ProAir HFA well before each use.
  • Always use the inhaler device provided.
  • Don't change your dose or the prescribed dosing schedule without asking your healthcare provider.


Store your ProAir HFA inhaler at room temperature between 59 and 77 degrees F (15 and 25 degrees C). Keep your device away from heat, direct light, and humidity. Do not puncture the canister or expose it to open flame. ProAir HFA canisters can burst if exposed to extreme temperatures. Don’t store your device in the bathroom. Store your inhaler with the mouthpiece down. Different brands of Albuterol have different storage needs. Ask your pharmacist how to store the brand you use if you have questions.

Keep your medications out of reach of children and pets, ideally locked in a cabinet or closet.

If you plan to travel with ProAir HFA, get familiar with your final destination's regulations. In general, be sure to make a copy of your ProAir HFA prescription. If possible, keep your medication in its original container from your pharmacy with your name on the label. If you have any questions about traveling with your medicine, be sure to ask your pharmacist or healthcare provider.

Discard all unused and expired drugs, but do not pour them down the drain or into the toilet. Ask your pharmacist or healthcare provider about the best ways to dispose of this medicine. And check out drug take-back programs in your area.
