    • are allergic to paracetamol, phenylephrine or any of the other ingredients (see section 6 for further information)
    • have a serious heart condition
    • are taking antidepressant drugs called monoamine oxidase inhibitors (MAOI’s) or have taken them within the last 14 days – these are medicines such as moclobemide, phenelzine and isocarboxazid

Other medicines and this medicine

Tell your doctor or pharmacist if you are taking, have recently taken or might take other medicines especially:

  • medicines to treat high cholesterol levels which reduce the amount of fat in the blood such as cholestyramine
  • medicines to control feeling sick or being sick such as metoclopramide or domperidone
  • medicines called anti-coagulants, which are used to thin the blood such as warfarin or other coumarins – you may take occasional doses of paracetamol but should consult your doctor if you need to take it on a regular basis
  • barbiturates (for epilepsy or to help you sleep), such as phenobarbitones
  • tricyclic antidepressants such as imipramine, amitriptyline
  • antidepressant drugs called monoamine oxidase inhibitors (MAOI’s) or have taken them within the last 14 days – these are medicines such as phenelzine and isocarboxazid

  • other decongestant drugs such as ephedrine or xylometazoline
  • flucloxacillin (antibiotic), due to a serious risk of blood and fluid abnormality (high anion gap metabolic acidosis) that must have urgent treatment and which may occur particularly in case of severe renal impairment, sepsis (when bacteria and their toxins circulate in the blood leading to organ damage), malnutrition, chronic alcoholism, and if the maximum daily doses of paracetamol are used.

Contains paracetamol.

Do not take anything else containing paracetamol while taking this medicine.

Contains 2.4 g of sucrose (sugar) per sachet. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

This medicine contains 53 mg aspartame in each sachet. Aspartame is a source of phenylalanine. It may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine builds up because the body cannot remove it properly.

3. How to take this medicine

Pour the contents of 1 sachet into a standard mug. Fill the mug to below the brim with approximately 250ml (8 fluid oz) of hot, but not boiling, water.

Do not take more medicine than the label tells you to. If you do not get better, talk to your doctor.

Do not take for longer than 3 days, unless your doctor agrees.

If you take more of this medicine than you should

Talk to a doctor at once if you take too much of this medicine even if you feel well. This is because too much paracetamol can cause delayed, serious liver damage. You may experience symptoms of dizziness, palpitations (irregular or forceful heartbeat), stomach pain, high blood pressure with headache, unhealthy pale appearance (pallor), feeling sick (nausea) or vomiting if you take too much of this medicine. If you forget to take this medicine:
