Most people with asthma will be prescribed a reliever inhaler (also known as a blue inhaler).

What is the normal dosage for Salbutamol/Ventolin?

As Salbutamol is a reliever inhaler it is designed to give instant relief of asthma symptoms. Your dosage will be tailored so that it can help treat the cause of your asthma.

For example, patients who find that their asthma is aggravated by exercise may be advised to take 2 puffs of Salbutamol before exercise.

What is the maximum dosage of Salbutamol?

Most physicians will recommend 1-2 puffs up to 4 times in 24 hours. However, in the event of moderate to severe asthma the dosage can be increased.

What to do if you regularly exceed your prescribed dosage of Ventolin/Salbutamol?

If you find you are regularly having to use your blue inhaler, it is a sign that your asthma is worsening or not getting treated appropriately.
