How to Use a Metered-Dose Inhaler with a Spacer Correctly
Correct inhaler technique helps medicine reach the lungs. Follow the essential spacer steps, avoid common errors, care for the device, and know when asthma needs urgent treatment.
Key takeaways
- Device instructions differ, so first confirm that the inhaler is a pressurised metered-dose inhaler and that the spacer is compatible.
- Shake the inhaler, fit it to the spacer, breathe out, press one puff, then inhale slowly and deeply or use the advised tidal-breathing method.
- Poor technique can look like treatment failure; ask a clinician, nurse, or pharmacist to watch your technique regularly.

Short answer: a spacer makes a pressurised metered-dose inhaler easier to coordinate and can improve delivery to the lungs. The exact steps depend on the device, so follow its leaflet and have a trained professional check your technique.
Before you start
- Confirm the inhaler and spacer are compatible.
- Remove the cap, check the mouthpiece is clear, and shake the inhaler as directed.
- Sit or stand upright.
- If the inhaler is new or has not been used recently, follow its priming instructions.
Common single-breath method
- Insert the inhaler firmly into the spacer.
- Breathe out gently, away from the device.
- Seal the lips around the spacer mouthpiece.
- Press the inhaler once.
- Breathe in slowly and deeply. A whistle on some spacers means the breath is too fast.
- Hold the breath for up to 10 seconds if comfortable, then breathe out slowly.
- If another puff is prescribed, wait as directed, shake again, and repeat one puff at a time.
When normal breathing is used
Young children and people unable to take a deep breath may be advised to breathe normally through the spacer for several breaths after one puff. A well-fitted mask may be needed. Ask the asthma team to demonstrate the correct number of breaths for the specific device.
Common mistakes
- Firing several puffs into the spacer together
- Breathing in too fast or waiting too long after pressing
- Failing to shake between puffs
- Using a poorly fitting mask or losing the mouth seal
- Not rinsing the mouth after an inhaled corticosteroid
- Allowing the spacer to become damaged, dirty, or heavily statically charged
Cleaning and review
Follow the manufacturer’s cleaning and replacement instructions; methods differ among spacer materials. Let the device air-dry when directed rather than wiping the inside. Bring the inhaler and spacer to appointments for regular technique checks.
Complementary care does not replace inhalers
Homeopathic products cannot rapidly open narrowed airways or control airway inflammation. Continue preventer and reliever medicines exactly as prescribed, and follow the written asthma action plan. Discuss any complementary product with the care team.
Use the reliever and follow the action plan. Call emergency services if breathing is very difficult, the person cannot speak normally, lips look blue or grey, symptoms rapidly worsen, or the reliever is not helping. Do not delay for steam or complementary remedies.
When Should You Seek Medical Help?
Homeopathy works best as a complementary approach. Please consult a qualified medical professional immediately if you experience:
- ! Symptoms lasting more than 7–10 days without improvement
- ! High fever (above 103°F / 39.5°C) or rapidly worsening condition
- ! Severe chest pain, breathing difficulty, or neurological symptoms
- ! Symptoms in infants under 6 months, the elderly, or immunocompromised individuals
