The Day capsules also contain:

  • caffeine

These capsules are used for the relief of the symptoms of colds and flu, including aches and pains, sore throat, headache, nasal congestion (blocked nose) and feverishness (high temperature). The Day capsules can also relieve tiredness and drowsiness.

  • are allergic to paracetamol, caffeine, phenylephrine or any of the other ingredients

Warnings and precautions

Talk to your doctor or pharmacist before taking this medicine if you:

  • you have 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) and being sick (vomiting).

Other medicines and this medicine

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

  • medicines to treat high cholesterol levels which reduce the amount of fat in the blood such as colestyramine
  • 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
  • medicines used to treat gout such as probenacid
  • medicines to treat irregular heartbeats (arrhythmias) e.g. digoxin
  • medicines called ergot alkaloids, which are used to treat severe headaches
