This fact sheet explains how to correctly use a puffer, also known as a pressurised metered dose inhaler (pMDI). It gives clear, step-by-step instructions on how to prepare, use, clean and store your inhaler safely. The fact sheet is designed to help people with lung conditions like asthma or chronic obstructive pulmonary disease (COPD) use their puffer the right way, so they get the full benefit of their medication. Using an inhaler correctly is the best way to get medication into the lungs, meaning you get the right amount and have fewer side effects.
Before using your puffer for the first time—or if you haven’t used it for a week—you’ll need to “prime” it by spraying a test puff or more, depending on your inhaler. Always check the instructions for your specific device.
The guide explains how to breathe in slowly and press the canister at the same time to release one puff of medicine, and how to hold your breath afterward to help the medicine reach your lungs. If you need a second puff, it tells you how long to wait before repeating the steps.
The fact sheet also explains how to know when your inhaler is running out of medicine. Some inhalers have a dose counter that shows how many puffs are left. If yours doesn’t, you can keep track by counting how many puffs you use each day.
Cleaning instructions are included for different coloured puffers. Some should be wiped with a dry tissue, while others can be rinsed in warm water (after removing the metal canister). You’ll also learn how to store your puffer properly—away from heat, sunlight, and moisture—and how to safely dispose of it when it’s finished.
This easy-to-follow guide helps you feel confident using your inhaler and managing your lung condition. If you’re unsure about anything, speak to your doctor, nurse, or pharmacist.
