1 What Co-codamol tablets are and what they are used for

Co-codamol contains two different medicines called codeine phosphate and paracetamol. Co-codamol tablets belong to a group of medicines called analgesics, which act to relieve pain. Co-codamol tablets can be used in children over 12 years of age for the short-term relief of moderate pain that is not relieved by other painkillers such as paracetamol or ibuprofen alone.

Do not take less than four hours after taking other painkillers.

2 Before you take

  • This medicine contains codeine which can cause addiction if you take it continuously for more than three days. This can give you withdrawal symptoms from the medicine when you stop taking it (see ‘If you stop taking the tablets’).
  • If you take a painkiller for headaches for more than three days it can make them worse.

Do not take Co-codamol tablets:

  • if you are allergic (hypersensitive) to paracetamol, codeine phosphate or other opioids, or any of the ingredients in the tablet (see section 6)
  • if you have diarrhoea caused by poisoning or severe bloody diarrhoea (pseudomembranous colitis)
  • if you have difficulty breathing, or other chronic lung disease
  • if you are having an asthma attack.
  • for pain relief in children and adolescents (0-18 years of age) after removal of their tonsils or adenoids due to obstructive sleep apnoea syndrome
  • if you know that you metabolise very rapidly codeine into morphine
  • if you are breastfeeding

Check with your doctor or pharmacist before taking Co-codamol tablets if you have:

  • liver or kidney problems
  • diseased adrenal glands (Addison’s disease) or high blood pressure caused by a tumour near a kidney (phaeochromocytoma)
  • inflammatory bowel disease
  • gall bladder disease or gall stones
  • recently had surgery on your gastro-intestinal tract or urinary system
  • an enlarged prostate gland and have difficulty urinating and are male
  • epilepsy or suffered head injury or raised pressure in the skull (may cause painful eyes, changes in vision or headache behind the eyes)
  • an underactive thyroid gland
  • muscle weakness (myasthenia gravis)
  • low blood pressure or are in shock
  • suffered from alcoholism, drug abuse or dependence or mental illness.

Warnings and precautions

Codeine is transformed to morphine in the liver by an enzyme. Morphine is the substance that produces pain relief. Some people have a variation of this enzyme and this can affect people in different ways. In some people, morphine is not produced or produced in very small quantities, and it will not provide enough pain relief. Other people are more likely to get serious side effects because a very high amount of morphine is produced. If you notice any of the following side effects, you must stop taking this medicine and seek immediate medical advice: slow or shallow breathing, confusion, sleepiness, small pupils, feeling or being sick, constipation, lack of appetite.

Children and adolescents

Use in children and adolescents after surgery

Co-codamol should not be used for pain relief in children and adolescents after removal of their tonsils or adenoids due to Obstructive Sleep Apnoea Syndrome.

Use in children with breathing problems

Co-codamol is not recommended in children with breathing problems, since the symptoms of morphine toxicity may be worse in these children.
