what are the names of preventer inhalers
The type of medicine commonly used in preventer inhalers is a steroid. Steroids work by reducing the inflammation in the airways. When the inflammation has gone, the airways are much less likely to become narrow and cause symptoms such as wheezing.f you have an exacerbation (flare-up) of your asthma symptoms, you may be advised to take the preventer inhaler more often. It takes 7-14 days for the steroid in a preventer inhaler to build up its effect. This means it will not give any immediate relief of symptoms (like a reliever does).
