Asthma relief inhalers: what to use, when, and how

Asthma can feel unpredictable, but the right inhaler and good technique make flare-ups a lot easier to handle. This page helps you quickly understand the main types of inhalers, when to use them, and simple tricks to get the medicine where it belongs — your lungs.

How inhalers work — rescue vs controller

There are two basic roles for inhalers: rescue (fast relief) and controller (daily prevention). Rescue inhalers like albuterol (often called Ventolin) open airways fast when you’re wheezy or short of breath. Controller inhalers usually contain steroids or long-acting bronchodilators that lower inflammation over weeks, so attacks happen less often.

Device types matter too. Metered-dose inhalers (MDIs) spray medicine and often work best with a spacer. Dry powder inhalers (DPIs) require a strong, quick breath to pull the drug in. Nebulizers turn liquid medicine into a mist — useful for small children or during severe attacks when breathing is weak.

Picking the right inhaler and using it well

Talk to your clinician about which inhaler fits your lifestyle. If you need fast relief, carry a rescue inhaler and replace it before the expiry dose runs out. If you’re on a controller, take it every day even when you feel fine — skipping doses is the most common reason controllers stop working.

Technique beats brand. For MDIs: shake, breathe out fully, place the mouthpiece, press and breathe in slowly for 3–4 seconds, then hold your breath 5–10 seconds. Use a spacer if you struggle with timing — it reduces throat side effects and makes each puff more effective. For DPIs: load if needed, exhale away from the device, inhale quickly and deeply, then hold your breath. Rinse your mouth after steroid inhalers to lower the chance of thrush.

Watch for common side effects: tremor or fast heartbeat from rescue inhalers, hoarseness or oral thrush from inhaled steroids. If side effects bother you, don’t stop the medicine — bring it up with your prescriber. They can adjust dose, switch devices, or add a spacer.

Know when to seek help. If a rescue inhaler doesn’t bring quick improvement, your symptoms get worse, or you’re using rescue puffs more often than your action plan allows, get urgent medical help. Keep an asthma action plan and review it with your clinician each year or after any attack.
