Why is it prescribed?
Salbutamol is used to relieve and prevent bronchospasm associated with asthma, bronchitis, emphysema and other pulmonary disorders where bronchospasm is a complicating factor. It is also indicated in the prevention of exercise-induced bronchospasm.

- Your doctor or pharmacist should have instructed you on the proper use and care of your Ventolin®. It is advisable to have your technique reassessed by the pharmacist for the first 2 or 3 refills of your prescription.
- Remember to shake the inhaler before each use.

- When 2 inhalations are required, wait at one full minute between doses. This is rescue medication and should be carried with you at all times.
- Each canister usually contains 200 doses so it is important to keep a record of approximately when it should be replaced. To avoid problems, many people keep 2 inhalers on hand.

Salbutamol is a short-acting bronchodilator that acts at specific receptors in the body called beta2-adrenergic receptors. Stimulating these beta2-receptors in the bronchial smooth muscle causes the muscle to relax, allowing the bronchial tubes to dilate (widen). Salbutamol relieves the spasm in the small air passages in the lungs and so helps ease breathing problems.
Along with its needed effects, salbutamol may cause some unwanted or undesirable effects. Generally, salbutamol is well tolerated and many people will not experience unwanted effects. The severity and duration of these effects are dependant on many factors including duration of therapy, dose, route of administration and individual response. Possible unwanted effects include:
- cough (inhaled preparations only)
- slight palpitations (awareness of heart beat)
- dry mouth and throat (inhaled preparations only)
- increased heart rate
- muscle cramps
- trouble sleeping
- unusual taste
- angina (chest pain/discomfort)
- increase in blood pressure
- hyperactivity in children
Many of these unwanted effects, especially the most common ones, may disappear with continued use. Check with the doctor or pharmacist if any of them continue or become bothersome.
Poor response to salbutamol can often be attributed to improper use of the delivery device. Be sure to follow the directions given to you by your pharmacist and read the patient instructions that are provided with each product. Never exceed the maximum dosage set by your physician. If you find that you are not responding to your usual dose, it could mean that your asthma is worsening and you should contact your physician. Increasing the dose, especially over extended periods, can lead to decreasing response to the drug. Keep in mind that the bronchodilator action should last between 2 and 6 hours. If you are using salbutamol for an acute asthma episode and the condition continues or worsens, call your doctor or seek medical attention immediately. If you need to use salbutamol to relieve symptoms more than 3 times a week you should also be using an anti-inflammatory medication (e.g. beclomethasone, fluticasone).
