What to do if…
your rescue inhaler is not relieving symptoms the way it usually does

Short answer

Treat this as potentially serious: sit upright, use your reliever exactly as your asthma action plan/NHS advice says, and call 999 if you’re not improving quickly or you’re getting worse.

Do not do these things

  • Do not “wait it out” if you’re struggling to breathe or your reliever is not helping as usual.
  • Do not lie flat or curl up; it can make breathing harder.
  • Do not take random extra doses beyond the maximum you’ve been told to use in an asthma attack.
  • Do not drive yourself to A&E if this is an asthma attack.
  • Do not keep using an inhaler you suspect is empty, blocked, or misfiring without switching to a working one (if you have another) and getting urgent help.

What to do now

  1. Get to a safer pause and sit upright. Loosen tight clothing, keep your shoulders relaxed, and focus on slower breaths.
  2. If you have your personal asthma action plan, follow it now. If you do not, use the NHS asthma-attack dosing below (only if this matches what you’ve been prescribed).
  3. Use your reliever properly (common reasons it “doesn’t work” are technique/device issues):
    • Shake the inhaler (if it’s a metered-dose inhaler) and make sure the mouthpiece is clear.
    • Use a spacer if you have one (it can make the dose more effective).
    • If there’s a dose counter, check it isn’t at/near zero. If you have another reliever inhaler available, switch to it.
  4. If this might be an asthma attack, use the NHS “asthma attack” steps:
    • If you have a blue reliever inhaler: take 1 puff every 30–60 seconds (shake between puffs, use a spacer if you have one), up to 10 puffs.
    • If you use an AIR/MART inhaler (used for both prevention and relief): take 1 puff every 1–3 minutes, up to 6 puffs.
    • If your own plan gives a different maximum, follow your plan.
  5. Call 999 for an ambulance immediately if any of these are true:
    • You’re getting worse at any time, or
    • You do not feel better after the maximum dose, or
    • You do not have an inhaler, or you can’t get it to work. Tell the call handler you’re having an asthma attack / breathing emergency.
  6. While waiting for help: if symptoms are no better after 10 minutes and the ambulance has not arrived, use the inhaler again up to the same maximum dose.
  7. If you’re not at “attack” level but the reliever is clearly weaker than usual: treat it as urgent today:
    • If your GP is open, ask for an urgent same-day GP/asthma nurse call-back.
    • If your GP is closed, call NHS 111 for urgent advice.

What can wait

  • You do not need to figure out the “exact cause” right now (trigger, infection, weather, stress).
  • You do not need to make long-term medication changes in the moment unless your asthma action plan already tells you what to do.
  • You do not need to clean or troubleshoot equipment beyond quick checks (counter, blockage, correct assembly) until you’re stable and breathing comfortably.

Important reassurance

It’s common to panic when your usual reliever doesn’t feel reliable. Acting early is the safer choice here, and calling 999 is appropriate if you’re not improving—this is exactly what emergency services are for.

Scope note

These are first steps to keep you safe in the moment and get urgent care if needed. Once you’re stable, you’ll likely need a review of your asthma control, triggers, and inhaler technique.

Important note

This is general information, not a diagnosis or personalised medical advice. If you think you’re having an asthma attack or your breathing is worsening, treat it as urgent and seek emergency help.
