NHS medicines information on possible interactions with co-codamol and other medicines, herbal remedies and supplements.

About this information

This NHS content is written for people in England. Medicine names, availability, prescribing and services may differ in other countries.

Cautions with other medicines

Some medicines affect the way co-codamol works. Co-codamol can also stop some medicines working as well as they should.

Tell your doctor if you're taking:

  • sleeping pills or tranquillisers – particularly benzodiazepines such as diazepam, temazepam or lorazepam
  • antidepressants – some types do not mix with co-codamol
  • medicines to stop you feeling or being sick such as domperidone or metoclopramide
  • medicines that help to prevent blood clots (anticoagulants) such as warfarin
  • medicines to treat infections, particularly rifampicin or ciprofloxacin
  • epilepsy medicines
Taking co-codamol with other painkillers

It's safe to take co-codamol with ibuprofen and aspirin.

Do not take co-codamol with paracetamol, or other medicines that contain paracetamol, unless you've been advised to by a doctor. Co-codamol already contains paracetamol so you could be at risk of paracetamol overdose.

Medicines that have paracetamol in them include painkillers like Tramacet and co-dydramol, migraine remedies, and some cough and cold remedies like Lemsip and Night Nurse.

Important

Before taking co-codamol with any other medicines, check the label to see whether they contain paracetamol.

Mixing co-codamol with herbal remedies and supplements

There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to take with co-codamol.

They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
