Asthma attacks

An asthma attack is when symptoms of your asthma become very severe. It can be a medical emergency.

If your asthma affects your daily life, wakes you up from sleep or you have to use your inhaler three or more times a week, visit your GP as soon as possible.2

How to treat asthma

The most common treatment for asthma is using inhalers. You may need to take tablets if your asthma is more severe.3

There are videos available on Asthma UK’s website to show you how to use inhalers properly.

In some cases of severe asthma where other treatment options haven’t helped to relieve symptoms, injections or surgery might be recommended.3

Find out more about treatments for asthma on the NHS website.
