Asthma Spacer Use: How to Get the Most from Your Inhaler

When you use an asthma spacer, a hollow tube attached to an inhaler that holds medicine until you breathe it in. Also known as a holding chamber, it turns a quick puff of medication into a slow, deep breath—making your inhaler work far better, especially if you’re struggling to time your inhale with the spray. Without one, up to 80% of your dose can stick to your throat or mouth instead of reaching your lungs. That’s not just wasted medicine—it’s more side effects like hoarseness, thrush, and less control over your asthma.

Spacers aren’t just for kids. Adults use them too, especially if they’re on high-dose inhaled steroids or have trouble coordinating the puff-and-breathe motion. A spacer device, a simple plastic or metal tube with a mouthpiece and a mask or mouth opening. Also known as a valved holding chamber, it lets you breathe normally after the medicine is released, giving your lungs time to pull it in. This is why doctors recommend spacers with every metered-dose inhaler, especially for bronchodilator delivery, the process of getting fast-acting relief meds like albuterol deep into the airways. Also known as rescue inhaler use, it works best when the medicine doesn’t hit your tongue or throat first.

Many people skip the spacer because they think it’s extra work. But it’s not. It’s the difference between getting 10% of your dose and 80%. You don’t need fancy models—basic ones work fine. Clean yours weekly with soapy water and let it air dry. No rinsing or wiping inside—that can create static that traps medicine. And never share a spacer. It’s not just unhygienic; it can spread germs that trigger asthma flare-ups.
