Do I have to take my inhaler when I have no symptoms?
Understandably, when you don’t have any symptoms, it can be easy to forget to take your treatment or to feel like you do not need to. You must use your preventer inhaler every day, even when you are feeling well. Regular use of your preventer inhaler is the most effective way to keep you feeling this way.
What happens if I get side effects?
