Proair HFA (generic: albuterol) is a prescription medication used to treat bronchospasm (narrowing of airways) in people who have reversible obstructive airway disease, or to prevent exercise-induced bronchospasm. Proair HFA belongs to a group of drugs called beta agonists or bronchodilators which cause the smooth muscle of the airways to relax, making it easier to breathe.

This medication comes in an inhaler to be breathed slowly into the lungs.

Common side effects of Proair HFA include fast heartbeat, shakiness, headache, and nervousness.
