Which inhaler do you need and how do you get the most from it? If asthma gets in the way of your day, the right inhaler and good technique can make a huge difference. This guide explains common inhaler types, when to use each one, and simple steps to avoid wasted medicine.
There are a few main classes of inhalers. Know what each one is for so you can tell your doctor what you need.
- Rescue inhalers (short-acting beta agonists, SABA): fast relief for wheeze, cough, or tightness. Use during attacks or before exercise if your doctor recommends it.
- Controller inhalers (inhaled corticosteroids, ICS): reduce airway inflammation and prevent attacks. These are for daily use, even when you feel fine.
- Long-acting bronchodilators (LABA) and LABA/ICS combos: keep airways open longer. Often used with an inhaled steroid for better control.
- Long-acting muscarinic antagonists (LAMA): another option for persistent symptoms, usually added by a specialist.
Recent research from a large group of asthma patients showed higher cancer rates in some cases but also noted that inhaled corticosteroids were linked with a protective effect. That doesn’t mean they prevent everything, but it supports sticking with prescribed controller therapy when recommended.
Bad technique is one of the main reasons inhalers don’t work. Try these quick fixes:
- Shake the inhaler (if needed), breathe out fully, seal your lips around the mouthpiece, press and inhale slowly, then hold your breath for 5–10 seconds if you can.
- Use a spacer for metered-dose inhalers if you struggle with coordination. Spacers cut down on medicine lost to the throat and improve lung delivery.
- Keep track of doses and expiry dates. Replace inhalers when they run out, not when they feel empty.
- Clean the mouthpiece weekly and store the device where it won’t get very hot or frozen.
- Watch how often you use your rescue inhaler. Needing it more than twice a week (except before planned exercise) usually means your asthma isn’t well controlled — talk to your provider about stepping up your controller plan.
If you’re unsure which inhaler you have or how to use it, ask your pharmacist to show you or request a quick inhaler check at your next visit. Small changes in technique or switching to the right controller can cut symptoms and make life easier.
