Why Overuse Is Dangerous

Needing your salbutamol reliever inhaler more than twice a week (excluding before exercise) or using more than one canister a month indicates poorly controlled asthma requiring review of your preventer treatment — over-reliance on reliever inhalers without addressing underlying inflammation is associated with increased risk of severe asthma attacks and death.

Needing Reliever Very Frequently — Danger SignIf you need your salbutamol inhaler more than every 4 hours, or it's not providing relief, this indicates a severe asthma attack requiring emergency medical assessment — do not simply keep using more reliever without seeking help.
Reliever Overuse Signals Undertreated AsthmaFrequent reliever use is a warning sign that your regular preventer treatment needs review — this is one of the most important messages in modern asthma management, as reliance on relievers without adequate preventer treatment increases attack risk.
Is salbutamol addictive?
No — salbutamol is not addictive in the way some medications are, but frequent need for it reflects poorly controlled underlying asthma inflammation, which needs addressing with preventer treatment.
Can I use my child's inhaler if I have asthma?
No — inhalers should not be shared between individuals, both for hygiene reasons and because doses and specific medications may need to be tailored to each person.
