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.

Albuterol may cause serious side effects, including:

• worsening trouble breathing, coughing and wheezing (paradoxical bronchospasm). If this happens stop using albuterol and call your doctor or get emergency help right away. Paradoxical bronchospasm is more likely to happen with your first use of a new canister of medicine.
• heart problems including faster heart rate and higher blood pressure
• possible death in people with asthma who use too much albuterol
• allergic reactions. Call your doctor right away if you have the following symptoms of an allergic reaction:
  • itchy skin
  • swelling beneath your skin or in your throat
  • rash
  • worsening trouble breathing
• low potassium levels in your blood
• worsening of other medical problems in people who also use albuterol including increases in blood sugar

Do not use albuterol if you are allergic to albuterol sulfate or any of the ingredients in albuterol. 

Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of albuterol there are no specific foods that you must exclude from your diet when receiving albuterol.

Before you use albuterol, tell your doctor if you:

• have heart problems
• have high blood pressure (hypertension)
• have convulsions (seizures)
• have thyroid problems
• have diabetes
• have low potassium levels in your blood
• are pregnant or plan to become pregnant. It is not known if albuterol will harm your unborn baby. Talk to your doctor if you are pregnant or plan to become pregnant.
• are breastfeeding or plan to breastfeed. It is not known if albuterol passes into your breast milk. Talk to your doctor about the best way to feed your baby if you are using albuterol.

Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

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.

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.

Use albuterol exactly as your doctor tells you to use it.

Inhalational:

Albuterol aerosol spray

• Do not use the inhaler after the expiration date, which is on the packaging it comes in.
• Store between 15° and 25° C (59° and 77° F). Avoid exposure to extreme heat and cold. For best results, canister should be at room temperature. Store the inhaler with the mouthpiece down. Shake well before each spray.
• Do not puncture. Do not use or store near heat or open flame. Exposure to temperatures above 120°F may cause bursting. Never throw container into fire or incinerator.
• It is very important to keep the plastic actuator clean so the medicine will not build-up and block the spray. Do not try to clean the metal canister or let it get wet. The inhaler may stop spraying if it is not cleaned correctly. Wash the actuator at least once a week with warm water and let it air-dry completely.
• As with all aerosol medications, it is recommended to prime the inhaler before using for the first time and in cases where the inhaler has not been used for more than 2 weeks. Prime by releasing four “test sprays” into the air, away from your face.

A) Albuterol aerosol spray

• Before you reach 200 sprays, you should refill your prescription or ask your doctor if you need another prescription for albuterol HFA.
