People with asthma prescribed the wrong kind of inhaler were behind a lot of preventable deaths, a leading health charity told Good Morning Britain.
Asthma UK's Kay Boycott said some sufferers were under-prescribed inhalers designed to prevent an attack, while too many reliever inhalers were given to patients.
"What we'll say is with an asthma attack, you'll need to start hours, days, weeks before, so if you have got hay fever, start taking your preventer before the hay fever season starts to prevent them."
