Researchers have shown that using inhalers too often can actually make asthma worse.
Scientists from Leicester University, UK have discovered that common reliever inhalers, such as salbutamol (pictured), cause the lungs to release the chemicals that bring on attacks if taken too often.
The research has important consequences for people with poorly controlled asthma and for those who rely heavily on inhalers to relieve their symptoms. Lead researcher, Prof. Bradding, said if the finding is confirmed it could lead to the development of new treatment strategies.
Asthma UK who funded the research, said they urge people who need to use their reliever inhaler three or more times a week to visit their doctor to have their symptoms reviewed.
