Frequently asked questions
How often can I use my salbutamol inhaler?
For quick relief as needed, but if you need it more than a couple of times a week your asthma control needs reviewing. Overuse is a warning sign.
Is salbutamol a steroid?
No — it is a fast-acting bronchodilator (reliever). Preventer inhalers, which are often steroids, treat the underlying inflammation.
