There are different types of asthma inhaler treatment and it is very important to understand the difference. The blue inhaler (salbutamol) is often referred to as a reliever. It opens up narrowed breathing tubes to 'relieve' symptoms of difficulty breathing, tight chest and wheeze quickly.
The brown inhaler (Clenil, Qvar) is a steroid inhaler. If is often referred to as a preventer. If you find you need to use the blue inhaler more than 3 times per week, you should be taking a brown inhaler as well. It works by soothing swollen breathing tubes, much like steroid creams used in eczema. The brown inhaler will not help you unless it is used twice every day. It should be used for a minimum of 3 months. If your asthma symptoms are better after this time you may be able to reduce the dose or even stop it.
