Overview

Albuterol is a prescription medication used to treat bronchospasm (narrowing of airways) in people who have reversible obstructive airway disease. It may also used to prevent exercise-induced bronchospasm. Albuterol belongs to a group of drugs called beta agonists. These cause the smooth muscle of the airways to relax, making it easier to breathe.

Albuterol comes as a tablet, a syrup, and an extended release tablet to take by mouth. The tablets and syrup are usually taken three or four times a day. The extended release tablets are usually taken once every 12 hours. 

Albuterol also comes as a solution to be inhaled into the mouth using a nebulizer and is usually used 3 or 4 times a day.

This medication also comes as aerosol to inhale by mouth using an inhaler. When the aerosol is used to treat or prevent symptoms of lung disease, it is usually used every 4 to 6 hours as needed. When the aerosol is used to prevent breathing difficulty during exercise, it is usually used 15 to 30 minutes before exercise.

Common side effects include fast heartbeat, shakiness, and nervousness.

Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant. 

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Albuterol falls into category C. There are no good studies that have been done in humans with albuterol. But in animal studies, pregnant animals were given this medication, and the babies did not show any medical issues related to this medication.

Breastfeeding

Tell your doctor if you are breastfeeding or plan to breastfeed. 

It is not known if albuterol crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using albuterol.

Quick facts

If your symptoms worsen when you use an albuterol inhaler, contact your doctor right away. This may indicate either a worsening of your asthma or a reaction to the medication.

Throw away the albuterol canister after you have used the labeled number of inhalations even if it still contains some liquid and continues to release a spray when it is pressed. The spray may not contain the correct amount of medication.

Call your doctor if you feel albuterol no longer controls your symptoms.
