Learn the 8 essential steps to use your inhaler correctly so medicine reaches your lungs, not your throat. Fixing your technique can cut side effects, prevent hospital visits, and make your treatment work as it should.
When you need quick relief from asthma or COPD symptoms, a metered-dose inhaler, a handheld device that releases a precise puff of medication with each use. Also known as a MDI, it’s one of the most common tools for managing breathing problems — but only if you use it right. Many people think shaking and spraying is enough, but if you don’t coordinate your breath with the puff, most of the medicine ends up in your mouth or throat — not your lungs. That’s why proper technique isn’t just helpful, it’s essential.
A metered-dose inhaler doesn’t work alone. It’s paired with specific drugs, like bronchodilator, a type of medication that opens up airways quickly during an attack (think albuterol) or corticosteroid, a long-term anti-inflammatory used daily to prevent flare-ups (like fluticasone). These aren’t interchangeable. One is for emergencies, the other is for prevention. Mixing them up — or skipping doses — can make symptoms worse. And while you might see people using spacers (those plastic tubes attached to the inhaler), not everyone knows they help kids and older adults get the full dose without needing perfect timing.
It’s not just about the device. The real issue is consistency. People stop using their preventer inhalers when they feel fine — but that’s when they matter most. Others use their rescue inhaler too often, which signals their condition isn’t under control. The metered-dose inhaler is only as good as the person using it. That’s why so many articles here focus on proper use, side effects, and what happens when things go wrong — like oral thrush from steroid inhalers, or the danger of over-relying on quick fixes.
You’ll find posts here that explain how to use your inhaler with or without a spacer, why some people need two different devices, and how to tell if your inhaler is empty. There’s also guidance on what to do if you’re using it but still struggling to breathe — because no device works if it’s not part of a bigger plan. Whether you’re new to inhalers or have been using one for years, there’s something here that can help you use it better, safer, and more effectively.
