What to do if…
you think you have taken too much paracetamol or acetaminophen from multiple products

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

Short answer

Stop taking anything containing paracetamol now and get urgent medical advice, even if you feel well. If someone is seriously unwell, has trouble breathing, collapses, has a seizure, or loses consciousness, call 999.

Do not do these things

  • Do not take “one more dose” while you work it out.
  • Do not take any other cold, flu, sleep, migraine, or pain product until you have checked whether it contains paracetamol.
  • Do not drink alcohol until urgent medical advice says what is safe for your situation.
  • Do not try to make yourself vomit or “flush it out”.
  • Do not wait for symptoms to appear before getting advice.
  • Do not drive yourself to A&E if you are told to go; ask someone else to take you or call for an ambulance.

What to do now

  1. Pause all paracetamol immediately.
    Put the packets, bottles, sachets, and tablets out of reach so you do not take another dose on autopilot.

  2. Check every product taken in the last 24 hours.
    Look for “paracetamol” on UK labels. If a product was bought outside the UK, also check for “acetaminophen”. Include tablets, capsules, liquids, sachets, cold and flu remedies, migraine medicines, night-time medicines, and prescription painkillers such as co-codamol or co-dydramol.

  3. Make a quick best-effort timeline.
    Write down:

    • the product names
    • the strength, such as 500 mg tablets or 250 mg/5 mL liquid
    • how many doses were taken
    • the time of each dose, as closely as you can
    • who took it, and their age and approximate weight if it was a child or a smaller adult

  4. Get urgent advice now using the route for where you are.
    Say: “I may have taken too much paracetamol from multiple products and need urgent advice.”

    • In England, use 111 online or call 111.
    • In Wales, use NHS 111 Wales or call 111.
    • In Scotland, call NHS 24 on 111.
    • In Northern Ireland, contact your GP or GP out-of-hours service; if you cannot get advice quickly and a medicine overdose is possible, go to your nearest emergency department.

  5. Take the packets with you if you are told to attend.
    Bring the packets, bottles, blister strips, leaflets, and any remaining medicine. Do not delay seeking advice just because you cannot find everything.

  6. Treat emergency warning signs as 999 or A&E now.
    Call 999 or go to A&E if the person has severe breathing difficulty, collapse, loss of consciousness, a seizure, repeated vomiting, extreme drowsiness, severe confusion, or if you are seriously worried.

  7. If a child may have had too much, get urgent advice now.
    Do this even if the child seems well. If the child is very drowsy, struggling to breathe, having a seizure, collapsing, or very hard to wake, call 999.

  8. Do not guess at a substitute medicine.
    If you need pain or fever relief while waiting for advice, ask the urgent advice service what is safe given what has already been taken.

What can wait

  • You do not need to decide right now whether this was “definitely” an overdose.
  • You do not need to calculate the exact milligrams perfectly before contacting urgent advice.
  • You do not need to search forums, compare stories, or decide what treatment might be needed.
  • You do not need to feel embarrassed or prove you made a mistake. A best-effort timeline is enough to start.

Important reassurance

Accidental double-dosing can happen when paracetamol is spread across several products. Pausing now and getting advice early is the right move, even if you feel normal at first.

Scope note

This is first-steps only to stabilise the situation and connect you to urgent medical advice. Any assessment, blood tests, observation, or treatment decisions need to be made by clinicians or the urgent care service advising you.

Important note

This guide is general information, not medical diagnosis or personal medical advice. If there is any chance you have taken too much paracetamol, get urgent medical advice now and call 999 for emergency symptoms.
