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 USA guide

Short answer

Get to fresh air and stop breathing the fumes. If breathing is severe, worsening, or the person collapses, has a seizure, cannot be awakened, or is not breathing normally, call 911 now.

Do not do these things

  • Do not stay in the room to air it out while you are coughing, wheezing, or short of breath.
  • Do not mix cleaning products, especially bleach with ammonia, vinegar, acids, or other cleaners.
  • Do not spray more cleaner, air freshener, perfume, or aerosol to cover the smell.
  • Do not take hard test breaths to see if the fumes are gone.
  • Do not smoke or vape near the fumes.
  • Do not lie flat if you are short of breath; sit upright if you can.
  • Do not delay emergency help to look up the product if breathing is severe or the person is hard to wake.

What to do now

  1. Get away from the fumes. Leave the room or building and breathe fresh air. Bring children, pets, and anyone coughing or short of breath away from the area if you can do that without putting yourself back into the fumes.
  2. Ventilate only if it is quick and safe. If you can open a door or window without breathing more fumes, do that and leave again. If you would need to stay in the room or re-enter while symptomatic, stay out and tell 911, Poison Control, or building staff what happened.
  3. Keep breathing as easy as possible. Sit upright, loosen tight clothing, and take small steady breaths. Stay away from smoke, aerosols, strong odors, and more cleaning products.
  4. Rinse exposed eyes or skin. If cleaner got in your eyes or on your skin, rinse with running water for at least 15 minutes. Remove contaminated clothing if you can do so safely, keep it away from other people, and ask Poison Control what to do with it.
  5. Use prescribed breathing medicine if this fits your plan. If you have asthma, COPD, or another lung condition and you have a rescue inhaler or action plan, follow it. If symptoms are severe, not improving, or you need repeated rescue medicine, get urgent medical help.
  6. Call Poison Help for real-time guidance if symptoms are mild or moderate, you are unsure what you breathed, or products may have been mixed. In the USA, call 1-800-222-1222. Have the product container or label nearby if you can, but do not delay urgent help to find it.
  7. Share the key details. Tell Poison Help, 911, or clinicians the product names, whether anything was mixed, where it happened, how long you were exposed, what symptoms started, and whether symptoms improve in fresh air.
  8. Do not go back in until it seems clearly aired out and symptoms are not returning. If coughing, chest tightness, wheezing, dizziness, burning eyes, confusion, faintness, or shortness of breath comes back when you approach the area, leave again and get medical advice.

What can wait

  • You do not need to finish cleaning today.
  • You do not need to decide whether to throw away all cleaning products right now.
  • You do not need to identify a diagnosis before getting help.
  • You do not need to clean up the spill or smell yourself while you are symptomatic.
  • You do not need to decide today how to prevent every future exposure; focus on fresh air, symptoms, and safe help first.

Important reassurance

Cleaning fumes can irritate the throat, eyes, and lungs, and the feeling of not getting enough air can make anyone feel frightened. Many mild exposures improve after getting to fresh air, but breathing symptoms that are severe, persistent, or worsening deserve prompt medical advice.

Scope note

These are first steps for the first minutes and hours after indoor cleaning-fume exposure. Later decisions, such as medical follow-up, disposal of contaminated items, or cleanup help, may need support from Poison Control, a clinician, emergency responders, or another appropriate specialist.

Important note
