Most asthma medicines are breathed in through your mouth using an inhaler device. When you use the correct technique, the medicine travels smoothly from the inhaler into your airways. When the technique is incorrect, some of the dose can get stuck in your mouth or throat instead of reaching your lungs. 

Many people don’t realise they are using their asthma inhaler incorrectly. With so many different types of inhalers available, it’s important to know exactly how to use your device and whether you need a spacer to help you get the full dose. You can purchase a spacer at your local pharmacy or you can visit our online shop. 

Why Inhaler Technique Matters

• Helps your preventer and reliever medicines work properly 

• Ensures the right amount of medicine reaches your lungs 

• Lowers the risk of side effects in your mouth and throat 

Even small mistakes in technique can reduce how well your asthma is controlled. 

Different Types of Asthma Inhalers

There are several common asthma devices, including: 

• puffers (pressurised metered dose inhalers or pMDIs) – best used with a spacer 

• dry powder inhalers (DPIs) 

• soft mist inhalers (respimat) 

Each device works differently, so the steps for using them are not the same. Knowing which inhaler you have – and how to use it correctly – is essential.

2. How do I know if I’m using my inhaler properly? 

One of the most tell-tale signs your medicine isn’t getting to your lungs properly, is feeling it hit your tongue or throat when you take it. You may also notice a strong taste or an increase in side effects in your throat.  

Other signs like needing your reliever more often or still having symptoms despite using your preventer could be a signal of not using it correctly, or a signal your asthma is getting worse.  

A healthcare professional can watch you use your device and help correct any small mistakes and make sure your treatment is the best one for you.  

3. Do I need a spacer with my asthma inhaler?

Yes, a spacer is recommended for people using a puffer (pMDI). It helps the medicine get deeper into your lungs and reduces the amount left in your mouth or throat.  

4. What should I do if my inhaler doesn’t seem to be working? 

If your inhaler feels empty, blocked or less effective: 

• Check the dose counter (if your device has one) 

• Check if your device needs cleaning (especially important for reliever puffers) 
  • Cleaning instructions are included on each of our inhaler pages.
