Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Paracetamol & Codeine 500mg/8mg Tablets if you:

  • Have kidney or liver problems or alcoholic liver disease or a history of drug abuse.
  • Suffer from high blood pressure or have an irregular heartbeat (slow or rapid).
  • Have an under active thyroid gland or adrenal gland.
  • Have urinary or prostate problems.
  • Have recently had surgery on your stomach, suffer from gallstones, bowel disorders or abdominal pain or swelling.
  • Have ever suffered from convulsions or emotional problems.
  • Are suffering from any kind of shock.
  • Suffer from muscle weakness (myasthenia gravis).
  • 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).

Codeine is transformed to morphine in the liver by an enzyme. Morphine is the substance that produces the effects of codeine and relieves pain and symptoms of cold. Some people have a variation of this enzyme that can effect people in different ways. In some people, morphine is not produced or produced in very small quantities which means it will not provide enough pain relief or relieve their cold. 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: Paracetamol & Codeine 500mg/8mg Tablets 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 and adolescents with breathing problems: Paracetamol & Codeine 500mg/8mg Tablets are not recommended in children with breathing problems as the symptoms of morphine toxicity may be worse in these children.
