Salbutamol, also called albuterol, is a short-acting bronchodilator. It opens the airways and gives quick relief from wheezing and shortness of breath. It comes as an inhaler, a nebulizer solution, tablets, and syrup.
What Is Salbutamol Used For?
- Asthma attacks and wheezing
- Chronic obstructive pulmonary disease (COPD)
- Preventing breathing problems caused by exercise
How Does Salbutamol Work?
Salbutamol relaxes the muscles around your airways. The airways widen, and air flows more easily. The inhaler starts to work within minutes.
General Dosage Information
This is general information only. Your doctor sets the right dose for you, so follow your prescription and the label.
- For the inhaler, adults usually take one or two puffs (100 to 200 micrograms) when they need relief, up to every four to six hours.
- Salbutamol tablets or syrup are usually taken three or four times a day.
- If you need your inhaler more often than usual, see your doctor, because your asthma may need better control.
