ProAir HFA is a bronchodilator that is used to treat or prevent bronchospasm in people with reversible obstructive airway disease. Albuterol is also used to prevent exercise-induced bronchospasm.

ProAir HFA is for use in adults and children at least 4 years old.

ProAir HFA may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Follow all directions on your prescription label and read all medication guides. Use the medicine exactly as directed.

Do not allow a young child to use ProAir HFA without help from an adult.

To prevent exercise-induced bronchospasm, use this medicine 15 to 30 minutes before you exercise. The effects of albuterol inhalation should last about 4 to 6 hours.

Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

ProAir HFA, Proventil HFA, or Ventolin HFA must be shaken before each use. You do not need to shake ProAir RespiClick before using.

Do not try to clean or take apart the ProAir RespiClick inhaler device.

Always use the new inhaler device provided with your refill. Do not float a medicine canister in water to see if it is empty.

Your dose needs may change due to surgery, illness, stress, or a recent asthma attack. Do not change your dose or dosing schedule without your doctor's advice.

Store at room temperature away from moisture, heat, or cold temperatures.

Keep the cover on your ProAir RespiClick inhaler when not in use. Store Proventil or Ventolin with the mouthpiece down.

Keep the inhaler canister away from open flame or high heat. The canister may explode if it gets too hot. Do not puncture or burn an empty inhaler canister.

You should not use ProAir HFA if you are allergic to albuterol.

You should not use ProAir RespiClick if you are allergic to milk proteins.

Tell your doctor if you have ever had:

• heart disease, high blood pressure;

• a thyroid disorder;

• seizures;

• diabetes; or

• low levels of potassium in your blood.

Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether albuterol will harm an unborn baby. However, having uncontrolled asthma during pregnancy may increase the risk of premature birth, low birth weight, or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of preventing bronchospasm may outweigh any risks to the baby.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of albuterol on the baby.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

Use the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not use two doses at one time.

Get your prescription refilled before you run out of medicine completely.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of albuterol can be fatal.

Overdose symptoms may include dry mouth, tremors, chest pain, fast heartbeats, nausea, general ill feeling, seizure, feeling light-headed or fainting.

Rinse with water if ProAir HFA gets in your eyes.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
