Asthma 101

Albuterol, a short-acting beta2 adrenergic agonist, relaxes the muscles around you lung’s airways

Asthma facts and information

Asthma is a condition that makes it hard to breathe. Asthma makes people's airways—those large and small tubes that bring air into your lungs—tighten and become narrow. People who have asthma may:1

  • Wheeze
  • Be short of breath
  • Feel their chest is tight
  • Have an ongoing cough

That's why you need to talk with your healthcare provider if you have any of the symptoms above. Your healthcare provider can diagnose you and prescribe treatment to help you control asthma.

ProAir® HFA is a quick-relief inhaler, recommended for the treatment of asthma.2 In fact, ProAir® HFA is the # 1 prescribed quick-relief inhaler in the U.S.3 And it comes with a convenient dose counter that tells you:2

  • How many doses are left
  • When it's time to replace your inhaler. The counter numbers turn red letting you know it's time to refill your prescription.

Asthma and your airways

People with asthma have airways that are irritated and are sensitive to asthma triggers that can lead to an asthma attack. During an asthma attack your airways can become narrow or get closed off.1 An asthma attack is also called an exacerbation.1

Some common asthma triggers are:1

  • smoke
  • pollen
  • exercise

ProAir® HFA and asthma

The ProAir® HFA quick-relief inhaler works by delivering medicine that helps relax the muscles around the airways.1 But not all inhalers are the same.

The ProAir® HFA inhaler delivers a warmer, less forceful, longer-duration spray to give you more time to inhale your medicine.4 Find out here how the ProAir® HFA inhaler is designed with you in mind.

Approved Uses

ProAir® HFA (albuterol sulfate) Inhalation Aerosol is indicated in patients 4 years of age and older for the treatment or prevention of bronchospasm with reversible obstructive airway disease and for the prevention of exercise-induced bronchospasm.

Important Safety Information

  • If your symptoms become significantly worse when you use ProAir® HFA, contact your doctor immediately. This may indicate either a worsening of your asthma or a reaction to the medication, which may rarely occur with the first use of a new canister of ProAir® HFA. Either of these could be life-threatening
  • What to tell your doctor before using ProAir® HFA: If you have a heart, blood, or seizure disorder, high blood pressure, diabetes, or an overactive thyroid, be sure to tell your doctor. Also make sure your doctor knows all the medications you are taking – especially heart medications and drugs that treat depression – because some medications may interfere with how well your asthma medications work. Do not exceed the recommended dose
  • Side effects associated with ProAir® HFA included headache, rapid heart beat, pain, dizziness, and irritation of the throat and nose

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit, or call 1-800-FDA-1088
