What Is an Asthma Inhaler?

An asthma inhaler is a handheld device that delivers medication straight into your lungs. You get the drugs faster -- and with fewer side effects -- than you would if you took it by pill or IV.

How Does the Inhaler Work?

Asthma inhalers can deliver drugs in a variety of ways.

Metered dose inhalers (MDIs) provide the drug through a small, handheld aerosol canister. They work like a spray can. You push the inhaler, it sprays out the medicine, and you breathe it in. A tube-like gadget called a spacer can help kids or people with trouble breathing use an MDI more easily.

Dry powder inhalers (DPIs) require you to breathe in quickly and deeply. That can make them hard to use during an asthma attack when you can’t fully catch a deep breath. Read the instructions carefully if you get a different brand because they vary widely, and the new one may not work like your old one.

Nebulizers deliver medication through a mouthpiece or mask. They’re easier to use because you can breathe normally. That makes them good for children or people with severe asthma who may not be able to use an MDI or DPI properly.
