Salbutamol, also called albuterol, is sold under the brand name Ventolin for the prevention and treatment of asthma symptoms such as wheezing, coughing, and shortness of breath.

The drug belongs to a class of pharmacological agents called bronchodilators. It is commonly used as a “quick-relief” inhaler. People with asthma induced by exercise use salbutamol inhalers as preventive medicine.

Salbutamol works by relaxing the muscles around the air passages so they can dilate and make your breathing much easier.

Generally, the drug comes in an inhaler or puffer. Sometimes, salbutamol is given as tablets or capsules for people who cannot use an inhaler. The drug can also be given using a nebulizer, especially in those who have asthma or chronic obstructive pulmonary disease (COPD).


Follow all directions for the proper use of a generic salbutamol inhaler for asthma. If you still have questions regarding how to use an asthma inhaler, ask your doctor or pharmacist. You may receive an asthma action plan from your doctor on how to use a salbutamol inhaler and how many puffs (inhalations) you need to take for each dose.

Inhale this asthma medication orally as directed by your doctor, every 4 to 6 hours or as needed. Remember, the dosage of salbutamol inhaler is based on your medical condition and drug response. Do not increase or decrease your dose or use it more often than prescribed without your physician’s approval. Use this medicine at least half an hour before exercise if you are using it to prevent asthma induced by exercise.
