Albuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs.

Albuterol inhalation is used to treat or prevent bronchospasm, or narrowing of the airways in the lungs, in people with asthma or certain types of chronic obstructive pulmonary disease (COPD). It is also used to prevent exercise-induced bronchospasm.

Albuterol inhalation is for use in adults and children who are at least 4 years old. Always follow your doctor's directions when giving albuterol to a child.

It is important to keep albuterol on hand at all times. Get your prescription refilled before you run out of medicine completely. Keep using all of your other medications as prescribed by your doctor.

Talk with your doctor if any of your asthma medications do not seem to work as well in treating or preventing attacks. If it seems like you need to use more of any of your medications in a 24-hour period, talk with your doctor. An increased need for medication could be an early sign of a serious asthma attack.

Only use albuterol as prescribed by your physician. An overdose of albuterol can be fatal. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of albuterol can be fatal. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Before taking this medicine

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

Albuterol may increase the risk of death or hospitalization in people with asthma, but the risk in people with obstructive airway disease or chronic obstructive pulmonary disease (COPD) is not known.

To make sure albuterol inhalation is safe for you, tell your doctor if you have:

• heart disease, high blood pressure, congestive heart failure;

• a heart rhythm disorder;

• a seizure disorder such as epilepsy;

• diabetes;

• overactive thyroid; 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 albuterol inhalation exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use albuterol inhalation in larger or smaller amounts or for longer than recommended.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

You may need to prime your albuterol inhaler device before the first use. Your medicine comes with directions for priming if needed. You may also need to shake your albuterol device just before each use.

Keeping your inhaler clean is important to ensure you are receiving the medication. Clean the plastic actuator with the canister removed at least once a week. Your medicine comes with directions for properly cleaning your device.

Follow all medication instructions very carefully.

Do not allow a young child to use albuterol inhalation without help from an adult.

The usual dose of albuterol inhalation is 2 inhalations every 4 to 6 hours. To prevent exercise-induced bronchospasm, use 2 inhalations 15 to 30 minutes before you exercise. The effects of albuterol inhalation should last about 4 to 6 hours.

Seek medical attention if you think your asthma medications are not working as well. An increased need for medication could be an early sign of a serious asthma attack.

Use the dose counter on your albuterol inhaler device and get your prescription refilled before you run out of medicine completely. Always use the new inhaler device provided with your refill. Do not float a medicine canister in water to see if it is empty.

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