Warnings and precautions

Talk to your doctor or pharmacist before taking Paracetamol 500 mg Film Coated Tablets:

  • If you have liver or kidney problems.
  • If you are underweight.
  • If you regularly drink alcohol.

  • If you have severe infection or severe illnesses, including severe renal impairment or sepsis (when bacteria and their toxins circulate in the blood leading to organ damage), or you suffer from malnutrition, chronic alcoholism or if you are also taking flucloxacillin (an antibiotic). A serious condition called metabolic acidosis (a blood and fluid abnormality) has been reported in patients in these situations when paracetamol is used at regular doses for a prolonged period or when paracetamol is taken together with flucloxacillin.

    Symptoms of metabolic acidosis may include serious breathing difficulties with deep rapid breathing, drowsiness, feeling sick (nausea), being sick (vomiting) and loss of appetite.

During treatment with Paracetamol 500 mg Film Coated Tablets, tell your doctor straight away if you get a combination of these symptoms. You may need to avoid using this product altogether or limit the amount of paracetamol that you take.

Other medicines and Paracetamol 500 mg Film Coated Tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, particularly metoclopramide or domperidone (for nausea [feeling sick] or vomiting [being sick] or colestyramine (to lower blood cholesterol). If you take blood thinning drugs (anticoagulants e.g. warfarin) and you need to take a pain reliever on a daily basis, talk to your doctor because of the risk of bleeding. You can still take occasional doses of Paracetamol 500 mg Film Coated Tablets at the same time as anticoagulants.

Please inform your doctor or pharmacist if you are taking flucloxacillin (antibiotic), due to a serious risk of blood and fluid abnormality (called metabolic acidosis) that must have urgent treatment (see section 2).
