Overview

Quick-relief beta2-agonists quickly reduce symptoms. For this reason, people sometimes overuse them instead of adding the slower-acting, long-term medicines. Overuse of quick-relief medicines may be harmful.

If you overuse quick-relief beta2-agonists, you may feel that your asthma is under control. But, in fact, inflammation in your airways is becoming worse. This can put you in danger of having a severe, deadly attack (status asthmaticus).

Overuse:

• May delay medical care.
• May increase your chances of having a severe asthma attack.
• Can make quick-relief medicines less effective in the future.
• Treats only the early narrowing of bronchial tubes without treating long-term inflammation.

In general, you may need more long-term treatment if you are using quick-relief medicines on more than 2 days a week (except before exercise). Talk to your doctor if you are using your quick-relief medicine this often. Using these medicines often may mean that your symptoms and inflammation are not well controlled.
