What is a Pressurised Metered Dose Inhaler (MDI)?

A Pressurised Metered Dose Inhaler (MDI) is a device used to deliver medication directly to the lungs. It consists of a small canister containing medicine and a plastic actuator that helps to release the medicine. You press the canister to release a measured dose of medication, which you then inhale through your mouth. MDIs are commonly used to manage conditions like asthma or chronic obstructive pulmonary disease (COPD). For personalised advice and to ensure it's right for you, always speak to your doctor.

How do I use an MDI correctly?

To use an MDI correctly, follow these steps: First, shake the inhaler well. Then, remove the cap from the mouthpiece. Breathe out fully, keeping your mouth slightly open. Place the mouthpiece between your teeth and close your lips around it. Press down on the canister to release the medicine while you breathe in deeply and steadily. Hold your breath for about 10 seconds, then breathe out slowly. If you need to take more than one puff, wait about a minute between puffs. Always follow your doctor's instructions for the correct usage.

What should I do if my MDI seems to be not working properly?

If your MDI doesn’t seem to be working properly, check if the canister is empty or if the inhaler is clogged. You might need to clean the inhaler according to the manufacturer's instructions. Sometimes, a problem with the inhaler can affect how well it delivers the medication. If you’re still having issues, contact your doctor or pharmacist for help. They can check if the inhaler is the right one for you or if there might be another problem.
