Treatments for asthma: inhalers
What are the treatments for asthma?
For most people with asthma, most of the symptoms can be prevented with treatment. So, you are able to get on with normal life, school, work, sport, etc.
Inhalers
Most people with asthma are treated with inhalers. Inhalers deliver a small dose of drug directly to the airways. The dose is enough to treat the airways. However, the amount of drug that gets into the rest of your body is small so side-effects are unlikely, or minor. There are various inhaler devices made by different companies. Different ones suit different people. A doctor or nurse will advise on the different types. See a separate leaflet called 'Asthma - Inhalers'.
Inhalers can be grouped into 'relievers', 'preventers' and 'long acting bronchodilators'.
- A reliever inhaler is taken 'as required' to ease symptoms. The drug in a reliever inhaler relaxes the muscle in the airways. This makes the airways open wider, and symptoms usually quickly ease. These drugs are also called 'bronchodilators' as they dilate (widen) the bronchi (airways). There are several different reliever drugs. For example, salbutamol and terbutaline. These come in various brands made by different companies. If you only have symptoms every 'now and then', then the occasional use of a reliever inhaler may be all that you need. However, if you need a reliever inhaler three times a week or more to ease symptoms, a preventer inhaler is usually advised.
- A preventer inhaler is taken every day to prevent symptoms from developing. The drug commonly used in preventer inhalers is a steroid. There are various brands. 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. It takes 7-14 days for the steroid in a preventer inhaler to build up it's effect. Therefore, it will not give any immediate relief of symptoms. However, after a week or so of treatment, the symptoms have often gone, or are much reduced. It can take up to six weeks for maximum benefit. You should then not need to use a reliever inhaler very often, (if at all).
- A long acting bronchodilator may be advised in addition to a steroid inhaler. One may be needed if symptoms are not fully controlled by the steroid inhaler alone. The drugs in these inhalers work in a similar way to 'relievers', but work for up to 12 hours after taking each dose. They include salmeterol and formoterol. (Some brands of inhaler contain a steroid plus a long acting bronchodilator for convenience.)
