Proventil is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Proventil is used to treat or prevent bronchospasm in people with reversible obstructive airway disease. It is also used to prevent exercise-induced bronchospasm. Proventil may also be used for other purposes not listed in this medication guide.

When using the inhaler device for the first time, prime it by spraying 4 test sprays into the air, away from your face. Shake well before priming. Also prime the inhaler if you have not used it for 2 weeks or longer, or if you have dropped the inhaler.
The instructions below are for standard use of the inhaler and nebulizer devices. Your doctor may want you to use your device differently. Use only the inhaler device provided with your medicine or you may not get the correct dose.
To use the inhaler:
Shake the canister well just before each spray.
Uncap the mouthpiece of the inhaler. Breathe out fully. Put the mouthpiece into your mouth and close your lips. Breathe in slowly while pushing down on the canister. Hold your breath for 10 seconds, then breathe out slowly.
If you use more than one inhalation at a time, wait at least 1 minute before using the second inhalation and shake the inhaler again.
Keep your inhaler clean and dry, and store it with the cap on the mouthpiece. Clean your inhaler once a week by removing the canister and placing the mouthpiece under warm running water for at least 30 seconds. Shake out the excess water and allow the parts to air dry completely before putting the inhaler back together. Call your doctor right away if you feel that this medicine is not working as well as usual, or if it makes your condition worse.
