What to do if…
you are coughing or having trouble breathing after inhaling strong cleaning fumes indoors

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Get away from the fumes into fresh air now. If breathing is severe, getting worse, or you cannot speak normally, call 999.

Do not do these things

  • Do not stay in the room to finish cleaning while you are coughing or short of breath.
  • Do not mix any more cleaning products, including bleach with other cleaners, to try to remove or neutralise the smell.
  • Do not spray air freshener, aerosols, perfume, or more cleaner to cover the odour.
  • Do not smoke or vape.
  • Do not force deep breaths to test your lungs if that makes coughing or tightness worse.
  • Do not lie flat if you feel short of breath; sit upright.
  • Do not drive yourself to A&E if your breathing is affected.

What to do now

  1. Move to fresh air and stop the exposure. Leave the room or building if needed. Shut the product, put it down, and step away from it.
  2. Ventilate only if it is safe and quick. Open windows or doors from a safe position if you can do so without breathing more fumes. If not, stay out and ask someone else to ventilate when it is safe.
  3. Sit upright and breathe gently. Keep your shoulders relaxed, loosen tight clothing around your neck or chest, and take small steady breaths.
  4. Rinse irritated eyes or skin with running water. If your eyes sting, keep rinsing them with clean running water and do not put anything else in them unless a clinician tells you to. If skin is irritated, rinse it with plenty of water and remove contaminated clothing without pulling it over your face if possible.
  5. Use your prescribed breathing medicine if you have one. If you have asthma or another lung condition and this feels like your usual flare, use your reliever or rescue medicine exactly as your personal action plan says. If it is not helping, you need urgent help.
  6. Call 999 now if any danger signs are present. Call 999 if you have severe difficulty breathing, cannot get words out, are gasping or choking, have severe wheezing, chest tightness or chest pain, fainting, confusion, a seizure, or lips, skin, face, or palms that look very pale, blue, or grey.
  7. Use NHS 111 if symptoms are not severe but you are still worried. Use NHS 111 if coughing, wheezing, throat burning, eye or skin irritation, or shortness of breath is not settling in fresh air, you have asthma or COPD, you are pregnant, a child is affected, you may have mixed products, or you are unsure what you breathed in.
  8. Keep the product information. If it is safe, keep the bottle or label closed and away from you. Note what was used, whether anything was mixed, where it happened, whether windows were open, and when symptoms started.

What can wait

  • You do not need to decide right now whether you overreacted.
  • You do not need to finish cleaning today.
  • You do not need to work out the exact chemical or diagnose yourself before asking for help.
  • You do not need to throw away all cleaning products while you are still breathless or shaken.

Important reassurance

Strong cleaning fumes can irritate the throat, eyes, and airways, and that can feel frightening. Getting into fresh air, stopping the exposure, and using the right help route gives you the best chance of settling the situation safely.

Scope note

These are first steps for the first minutes and hours after indoor cleaning-fume exposure. Later decisions, especially if symptoms persist, recur, or you have asthma, COPD, pregnancy, or a child affected, may need urgent or same-day help from NHS 111, 999, A&E, a GP, or another qualified professional.
