Inhaler overuse ‘can cause harm’

POWERFUL inhalers used by asthma sufferers can make their lungs produce harmful chemicals and significantly increase the chances of an attack if used too frequently, researchers have claimed.

A new study on asthma treatments has found that, despite the importance of the valuable medical device, overuse can pose more harm than good to those suffering from the condition.

Inhalers are used to relieve asthma symptoms by relaxing the muscles in airways which have become narrowed by the illness, making it easier to breathe.
