Preventer inhalers are the main way to treat asthma. They build up your protection over time.
Each inhaler contains a low dose of steroid medicine called corticosteroids. This reduces the inflammation in your airways.
The less inflammation, the less likely you are to react to your asthma triggers.
Preventer inhalers (brown and other colours) are not for use when you are having an asthma attack. In an asthma attack, you need to use your reliever inhaler (usually blue). This will act quickly when symptoms come on.
Most people need to take their preventer inhaler twice a day. Once in the morning and once in the evening. It's important to take your preventer inhaler even when you feel well.
It can take 7 to 14 days for the medicine to build up its effect. After a week or so of treatment, you may notice your symptoms have gone. For some people, it can take up to 6 weeks.
You should notice that your asthma is more controlled when taken as prescribed. You will be less sensitive to your asthma triggers.
You also won't need your reliever inhaler as much, as it will be easier to exercise and sleep.
Preventer inhalers are the safest way for most people to lower their risk of asthma symptoms. All medicine has effects, but the risk from preventer inhaler medicine is very small.
Common side effects include a sore throat, a hoarse voice, and a mouth infection called thrush. You can avoid these by using a good inhaler technique.
It can help to rinse your mouth out with water after using your inhaler. This will help remove any medicine that’s stuck in your mouth.
If you have a hoarse voice that doesn't go away, speak to your healthcare professional.
