Overview
- The NHS says regular warfarin users face a higher risk of bleeding when taking paracetamol and should seek medical advice.
- Taking more than four 500mg tablets in 24 hours for longer than a few days may slow blood clotting and increase bleeding risk.
- People should avoid co-codamol or cold and flu products that also contain paracetamol to prevent accidental overdose.
- Those on treatment for epilepsy or tuberculosis are advised to consult a GP or pharmacist before using paracetamol.
- Severe allergic reactions are rare at recommended doses, but the NHS advises calling 999 if symptoms of anaphylaxis occur.
