What is albuterol?

Albuterol sulfate – otherwise known as albuterol or salbutamol – is a bronchodilator used to aid breathing and reduce wheeziness. The most common condition treated with albuterol is asthma. You can order salbutamol online here in inhaler, tablet, syrup or nebulizer form.

What is albuterol used for?

  • Asthma
  • Wheezing
  • Tight chest
  • Cough
  • Breathing difficulties
  • COPD

Albuterol is a type of medicine that comes as an oral medication, inhaler or nebulizer solution. It is used to open airways and make it easier to breathe, especially in conditions such as asthma and lung disease. Uses for albuterol include bronchitis, asthma and COPD.

How does albuterol work?

Albuterol is a short-acting, selective beta2-adrenergic receptor agonist, otherwise known as a bronchodilator.

Bronchodilators open the airways and make it instantly easier to breathe. Albuterol inhalers are administered orally by pressing down on the top section and breathing simultaneously to release the medicine.

As albuterol moves through the respiratory system, it relaxes the muscles leading to the lungs and lets air move through more easily. This also helps other medications reach the lungs more easily.

Types of albuterol?

Albuterol is administered orally, via various types of mechanisms. Aerosol (metered dose) inhalers use the medication in small aerosols that clip into the plastic casing. Dry inhalers are similar to aerosols but use powdered albuterol that the user inhales.

Nebulizers are a small machine that turns liquid into a mist that is easily breathed in.

There are benefits and drawbacks to each type of inhaler. Nebulizers take longer to work than inhalers but are very easy to use.

Albuterol can also be administered orally as a tablet or syrup.

What is the ideal dosage for albuterol?

People using an albuterol inhaler should take 2 puffs every 4-6 hours. It can also be inhaled half an hour before exercise or strenuous activity.

Tablets are 2-8mg, which can be instant or extended-release. The syrup contains 2mg of albuterol.

Does albuterol have side effects?

Most people will not experience side effects from the proper dosage of albuterol. Some of the more common albuterol sulfate side effects include:

  • Wheeziness and cough
  • increased heart rate
  • trembling and shaking
  • dizziness
  • increased thirst
  • nausea and vomiting
  • UTI
  • Cold and flu symptoms
  • Sore throat
  • Anxiety

Some more serious (but rarer) side effects include:

  • heart palpitations
  • cough
  • hives
  • difficult or irregular breaths
  • tight chest
  • difficulty sleeping
  • diabetes
  • high or low blood pressure
  • migraine
  • painful or difficult urination
  • cramp
  • hoarseness of voice and sore throat
  • potassium deficiency
  • rash

In very rare cases, albuterol can have the opposite effect. If that happens, the airways might close instead of open. If you start to experience any of the serious side effects of albuterol, seek medical assistance straight away.

Take dosage guidance seriously and pay attention to albuterol warnings carefully. If you are not sure, discuss with your doctor before taking any new medication.

Does albuterol interact with other medications?

Some medications that should not be taken with albuterol are:

  • beta-blockers
  • diuretics
  • digoxin
  • MAOIs
  • Tricyclic antidepressants

Does albuterol expire?

Albuterol expires one year after manufacturing. After this, its effectiveness may be reduced.

Conditions that might be helped by albuterol


Albuterol is one of the most common treatments for asthma. Two puffs of albuterol have been found to lower FEV (difficulty in breathing) and ease symptoms of asthma by relaxing the muscles in the respiratory system and opening airways.


Albuterol relaxes the muscles in the respiratory system and opens the airways, making it easier to breathe. Studies show that it can reduce coughing and well-being more effectively than antibiotics in smokers and non-smokers with bronchitis.

Liquid albuterol was given in this study at a concentration of 2mg/5ml.

Bronchospasm Prophylaxis

Albuterol inhalers are an effective treatment for bronchospasm in both powder and aerosol form. When used to treat exercise-induced bronchospasms, 200 μg of albuterol opens the airways making it easier to breathe.

Chronic Obstructive Pulmonary Disease

Multiple studies have found that a combination of albuterol and ipratropium is the best treatment for diseases in the group COPD. By opening the airways, 240 μg of albuterol helps to reduce the effort of breathing and increase pulmonary function.


Although more research is needed to establish the effectiveness of albuterol for treating COVID-19, studies have found it to be safe and likely effective. Albuterol opens the airways making breathing easier and helping other inhaled medications to reach the lungs.
