Asthma is a common, long-term condition where the airways are very sensitive to anything that
irritates them, making it harder to breathe.

Triggers differ from person to person. There may be others, so please discuss with your doctor.

The common symptoms of asthma are caused by the constricting of muscles around your airways making it hard to breathe.
Reliever Inhalers treat the symptoms you feel.

If you have asthma, your airways become swollen or inflamed. Though it can’t always be felt, this can make airways more sensitive to triggers, and cause symptoms.
Preventer Inhalers treat swelling & inflammation.

For people with asthma, this means treating both the symptoms (airway tightening) and what causes them (the underlying inflammation).
