Side effects of paracetamol

Side effects from paracetamol are rare, but can include:

  • an allergic reaction, which can cause a rash and swelling
  • flushing, low blood pressure and a fast heartbeat – this can sometimes happen when paracetamol is given in hospital into a vein in your arm
  • blood disorders, such as thrombocytopenia (low number of platelet cells) and leukopenia (low number of white blood cells)
  • liver and kidney damage if you take too much (overdose) – this can be fatal in severe cases

Speak to a pharmacist or doctor if you develop any troublesome side effects that you think could be caused by paracetamol.
