How to use your metered dose inhaler (MDI) with large volume spacer device
Inhalers are commonly prescribed for patients with asthma and chronic obstructive pulmonary disease (COPD) as they are very effective at delivering the medication straight to the lungs where it is needed.
Using your inhalers correctly is an important part of asthma or COPD treatment. You should be shown how to use inhalers properly by a healthcare professional when they are first prescribed.
You may occasionally experience problems using your inhalers, especially if it has been a while since you were shown the correct technique. This is very common and your healthcare professional can help you improve your inhaler technique.
Why is inhaler technique important?
- It allows the correct dose of medication to reach your lungs.
- It gives you better control of your condition.

Common problems
Common mistakes that people make with inhalers and spacers include:
- Not standing or sitting upright, or holding the inhaler upright.
- Not shaking the inhaler before using it and in between doses.
- Not breathing in soon enough after pressing the inhaler so the medication falls to the bottom of the spacer.
- Not remembering to hold your breath if you have inhaled using one steady breath. If you have used five normal breaths this is not necessary.
- Taking several puffs without waiting and not shaking the inhaler in between puffs.
- Not cleaning the spacer correctly. Follow the manufacturer’s instructions.
Useful tips
- Ensure the spacer is the correct one to fit your inhaler.
- If the spacer is in two parts, fit them together.
- If your inhaler contains a corticosteroid rinse your mouth out with water after your dose.
- Spacers are available in different sizes and with face masks if needed.
- Wash your spacer regularly, preferably twice a week. Follow the instructions in the leaflet provided with your spacer. Gently pull the two halves of the spacer apart. Do not take the valve apart. Wash the two halves in warm water which can contain a mild detergent such as washing up liquid or sterilising solution. Rinse thoroughly with clean water.
- Replace spacers every 6 to 12 months.
- Speak to your nurse or pharmacist if you experience problems using your inhaler and spacer device.
- Always read the patient leaflet provided with your inhaler and spacer for any specific instructions.
