Summary of Product Characteristics Updated 27-Sep-2018 | Omega Pharma Ltd
For excipients, see 6.1.
White, capsule-shaped tablet with dimensions of 17.55 mm x 7.5 mm and debossed on one face to read PCC.
Codeine is indicated in patients older than 12 years of age for the treatment of acute moderate pain which is not considered to be relieved by analgesics such as paracetamol or ibuprofen alone.
Suitable for migraine, headache, rheumatic pain, period pain, toothache and neuralgia
For oral administration only.
Adults (including the Elderly):
2 tablets taken with water every 4-6 hours. No more than 8 tablets in 24 hours.
Children aged 16 - 18 years:
1-2 tablets taken with water every 6 hours when necessary. Not more than 8 tablets in 24 hours.
Children aged 12 – 15 years:
1 tablet taken with water every 6 hours when necessary. Not more than 4 tablets in 24 hours.
Children aged less than 12 years:
Codeine should not be used in children below the age of 12 years because of the risk of opioid toxicity due to the variable and unpredictable metabolism of codeine to morphine (see sections 4.3 and 4.4).
The duration of treatment should be limited to 3 days and if no effective pain relief is achieved the patients/carers should be advised to seek the views of a physician.
Hypersensitivity to paracetamol, caffeine, codeine or any of the other constituents.
Conditions where morphine and opioids are contraindicated, e.g. acute asthma, respiratory depression, risk of paralytic ileus, acute alcoholism, head injuries, raised intra-cranial pressure and following biliary tract surgery.
In all paediatric patients (0-18 years of age) who undergo tonsillectomy and/or adenoidectomy for obstructive sleep apnoea syndrome due to an increased risk of developing serious and life-threatening adverse reactions (see section 4.4).
In women during breastfeeding (see section 4.6).
In patients for whom it is known they are CYP2D6 ultra-rapid metabolisers.
Care is advised in the administration of paracetamol to patients with severe renal or severe hepatic impairment. The hazard of overdose is greater in those with non-cirrhotic alcoholic liver disease.
Care should be taken in administering the product to any patient whose condition may be exacerbated by opioids, particularly the elderly, in whom there is increased sensitivity to the central and gastro-intestinal effects, those on concurrent treatment with other CNS depressant drugs, those with prostatic hypertrophy and those with inflammatory or obstructive bowel disorders. Patients with obstructive bowel disorders or acute abdominal conditions should consult a doctor before using this product.
Patients with a history of cholecystectomy should consult a doctor before using this product as it may cause acute pancreatitis in some patients.
Patients should be advised not to exceed the recommended dose, as taking a painkiller for headaches too often or for too long can make them worse.
Prolonged regular use, except under medical supervision, may lead to physical and psychological dependence (addiction) and result in withdrawal symptoms, such as restlessness and irritability once the drug is stopped. Patients should be advised that they should not take this product for more than 3 days continuously without consulting a doctor.
Excessive intake of caffeine (e.g. coffee, tea and some canned drinks) should be avoided while taking this product (see section 4.9: Overdose caffeine).
Patients should be advised not to take other paracetamol-containing products concurrently.
Codeine is metabolised by the liver enzyme CYP2D6 into morphine, its active metabolite. If a patient has a deficiency or is completely lacking this enzyme an adequate analgesic effect will not be obtained. Estimates indicate that up to 7% of the Caucasian population may have this deficiency. However, if the patient is an extensive or ultra-rapid metaboliser there is an increased risk of developing side effects of opioid toxicity even at commonly prescribed doses. These patients convert codeine into morphine rapidly resulting in higher than expected serum morphine levels.
General symptoms of opioid toxicity include confusion, somnolence, shallow breathing, small pupils, nausea, vomiting, constipation and lack of appetite. In severe cases this may include symptoms of circulatory and respiratory depression, which may be life-threatening and very rarely fatal.
Estimates of prevalence of ultra-rapid metabolisers in different populations are summarized below:
3.4% to 6.5%
1.2% to 2%
3.6% to 6.5%
Post-operative use in children
There have been reports in the published literature that codeine given post- operatively in children after tonsillectomy and/or adenoidectomy for obstructive sleep apnoea, led to rare, but life-threatening adverse events including death (see also section 4.3). All children received doses of codeine that were within the appropriate dose range; however there was evidence that these children were either ultra-rapid or extensive metabolisers in their ability to metabolise codeine to morphine.
Children with compromised respiratory function
Codeine is not recommended for use in children in whom respiratory function might be compromised including neuromuscular disorders, severe cardiac or respiratory conditions, upper respiratory or lung infections, multiple trauma or extensive surgical procedures. These factors may worsen symptoms of morphine toxicity.
If symptoms persist, patients should consult a doctor.
Keep out of the reach and sight of children.

How do I know if I am addicted?
If you take the medicine according to the instructions on the pack it is unlikely that you will become addicted to the medicine. However, if the following apply to you it is important that you talk to your doctor:
• You need to take the medicine for longer periods of time
• You need to take more than the recommended dose
• When you stop taking the medicine you feel very unwell but you feel better if you start taking the medicine again
The speed of absorption of paracetamol may be increased by metoclopramide or domperidone and absorption reduced by colestyramine. Cholestyramine should not only be administered not less than one hour after taking paracetamol.
The anticoagulant effect of warfarin and other coumarins may be enhanced by prolonged regular use of paracetamol with increased risk of bleeding. Occasional doses have no significant effect.
The use of drugs which induce hepatic microsomal enzymes, such as anticonvulsants and oral contraceptive steroids, may increase the extent of metabolism of paracetamol, resulting in reduced plasma concentrations of the drug and a faster elimination rate.
Drugs which induce hepatic microsomal enzymes, such as alcohol and barbiturates, may increase the hepatotoxicity of paracetamol, particularly after overdose.
There is limited evidence suggesting that paracetamol may affect chloramphenicol pharmacokinetics but its validity has been criticised and evidence of a clinically relevant interaction appears to be lacking. Although no routine monitoring is needed, it is important to bear in mind this potential interaction when these two medications are concomitantly administered, especially in malnourished patients.
CNS depression or excitation may occur if codeine is given to patients receiving monoamine oxidase inhibitors, or within two weeks of stopping treatment with them. The effects of CNS depressants (including alcohol) may be potentiated by codeine.
Concurrent use of codeine with antidiarrhoeal and antiperistaltic agents may increase the risk of severe constipation. Concomitant use of antimuscarinics or medications with antimuscarinic action may result in an increased risk of severe constipation, which may lead to paralytic ileus and/or urinary retention.
Quinidine can inhibit the analgesic effect of codeine.
Codeine may delay the absorption of mexiletine and thus reduce the antiarrhythmic effect of the latter. Codeine may antagonise the gastrointestinal effects of metoclopramide and domperidone. Cimetidine inhibits the metabolism of opioid analgesics resulting in increased plasma concentrations.
Naltrexone blocks the therapeutic effect of opioids.
Caffeine, a CNS stimulant, has an antagonistic effect towards the action of sedatives and tranquilisers (e.g. benzodiazepine and non-benzodiazepine hypnotics).
Caffeine may enhance the tachycardiac effect of some decongestant (e.g. ephedrine and pseudoephedrine).
Regular use of codeine during pregnancy may cause physical dependence in the foetus leading to withdrawal symptoms in the neonate. Administration of codeine during labour may depress respiration in the neonate. Opioid analgesics may cause gastric stasis during labour, increasing the risk of inhalation pneumonia in the mother.
Codeine should not be used during breastfeeding (see section 4.3).
At normal therapeutic doses codeine and its active metabolite may be present in breast milk at very low doses and is unlikely to adversely affect the breast fed infant.
However, if the patient is an ultra-rapid metaboliser of CYP2D6, higher levels of the active metabolite, morphine, may be present in breast milk and on very rare occasions may result in symptoms of opioid toxicity in the infant, which may be fatal.
Epidemiological studies in human pregnancy have shown no ill effects due to paracetamol and caffeine use in the recommended dosage, but patients should follow medical advice regarding its use.
Paracetamol is excreted in breast milk, but not in a clinically significant amount.
Patients should not drive or operate machinery if affected by drowsiness.
This medicine can impair cognitive function and can affect a patient's ability to drive safely. This class of medicine is in the list of drugs included in regulations under 5a of the Road Traffic Act 1988. When taking this medicine, patients should be told:
• The medicine is likely to affect your ability to drive
• Do not drive until you know how the medicine affects you
• It is an offence to drive while under the influence of this medicine
• However, you would not be committing an offence (called 'statutory defence') if:
• The medicine has been taken to treat a medical or dental problem and
• You have taken it according to the information provided with the medicine and
• It was not affecting your ability to drive safely
Adverse effects of paracetamol are rare, but hypersensitivity including skin rash may occur. There have been a few reports of blood dyscrasias including thrombocytopenia and agranulocytosis, but these were not necessarily causally related to paracetamol.
Respiratory, thoracic and mediastinal disorders such as bronchospasm in patients sensitive to aspirin and others NSAIDs are very rare. Hepatobiliary disorders such as hepatic dysfunction is very rare.
Skin and subcutaneous tissue disorders such as cutaneous hypersensitivity reactions including pruritus, sweating, purpura, urticarial and angioedema are very rare. Very rare cases of serious skin reactions have also been reported.
Renal and urinary disorders such as sterile pyuria (cloudy urine) is very rare.
High doses of caffeine may produce headache, tremor, nervousness, dizziness and irritability. The frequency of these is unknown.
Codeine can produce constipation and drowsiness. Occasional effects are nausea, vomiting, dyspepsia, acute pancreatitis in patients with a history of cholecystectomy, sweating, facial flushing, dry mouth, blurred or double vision, dizziness, postural hypotension, headache, vertigo, palpitations, allergic reactions (itch, skin rash, facial oedema), and difficulties in micturition (dysuria, increased frequency, decrease in amount). Side-effects which occur rarely include hallucinations, nightmares, restlessness and stomach cramps. The frequency and severity are determined by dosage, duration of treatment and individual sensitivity and are unlikely at this dosage. Tolerance and dependency can occur, especially with prolonged high doses of codeine. See also Section 4.9 'Overdose'.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
Liver damage is possible in adults who have taken 10g or more of paracetamol. It is considered that excess quantities of a toxic metabolite (usually adequately detoxified by glutathione when normal doses of paracetamol are ingested) become irreversibly bound to liver tissue. Ingestion of 5g or more of paracetamol may lead to liver damage if the patient has risk factors (see below).
Risk Factors: If the patient
- Is on long term treatment with carbamazepine, phenobarbitone, phenytoin, primidone, rifampicin, St John's Wort or other drugs that induce liver enzymes.
- Regularly consumes ethanol in excess of recommended amounts. Or
- Is likely to be glutathione deplete e.g. eating disorders, cystic fibrosis, HIV infection, starvation, cachexia.
Symptoms of paracetamol overdosage in the first 24 hours are pallor, nausea, vomiting, anorexia and abdominal pain. Liver damage may become apparent 12 to 48 hours after ingestion. Abnormalities of glucose metabolism and metabolic acidosis may occur. In severe poisoning, hepatic failure may progress to encephalopathy, haemorrhage, hypoglycaemia, cerebral oedema, coma and death. Acute renal failure with acute tubular necrosis strongly suggested by loin pain, haematuria and proteinuria, may develop even in the absence of severe liver damage. Cardiac arrhythmias and pancreatitis have been reported.
Immediate treatment is essential in the management of paracetamol overdose. Despite a lack of significant early symptoms, patients should be referred to hospital urgently for immediate medical attention. Symptoms may be limited to nausea or vomiting and may not reflect the severity of overdose or the risk of organ damage. Management should be in accordance with established treatment guidelines.
Treatment with activated charcoal should be considered if the overdose has been taken within 1 hour. Plasma paracetamol concentration should be measured at 4 hours or later after ingestion (earlier concentrations are unreliable) but results should not delay initiation of treatment beyond 8 hours after ingestion, as the effectiveness of the antidote declines sharply after this time. Activated charcoal should not be used if it is anticipated that oral methionine will be given to the patient. If required the patient should be given intravenous N-acetylcysteine, in line with the established dosage schedule. If vomiting is not a problem, oral methionine may be a suitable alternative for remote areas, outside hospital.
The effects in codeine overdosage will be potentiated by simultaneous ingestion of alcohol and psychotropic drugs.
Codeine overdose associated with central nervous system depression, including respiratory depression, may develop but is unlikely to be severe unless sedative agents have been co-ingested, including alcohol, or the overdose is very large. The pupils may be pin-point in size; nausea and vomiting are common. Hypotension and tachycardia are possible but unlikely.
Symptoms of codeine overdose also include cold clammy skin, confusion, convulsions, dizziness, drowsiness, nervousness or restlessness, miosis, bradycardia, dyspnoea, unconsciousness and weakness.
Management of codeine overdose should include general symptomatic and supportive measures including a clear airway and monitoring of vital signs until stable. Consider activated charcoal if an adult presents within one hour of ingestion more than 350 mg or a child more than 5 mg/kg. Give naloxone if coma or respiratory depression is present. Naloxone is a competitive antagonist and has a short half-life so large and repeated doses may be required in a seriously poisoned patient. A dose of 0.4-2mg is given intravenously or intramuscularly to adults, this is repeated at intervals of 2-3 minutes if necessary up to 10mg naloxone may be given. Observe for at least four hours after ingestion, or eight hours if a sustained release preparation has been taken. Codeine is not dialysable.
Caffeine overdose may cause diuresis, tachycardia, irritability, nervousness, restlessness, gastrointestinal disturbance and CNS stimulation such as agitation, excitement, insomnia and tremors. Lethal doses of caffeine tend to be between 5 - 10g. The management of caffeine toxicity is generally symptomatic and supportive (e.g. hydration). For acute ingestion, emesis or gastric lavage is advised.
Paracetamol has analgesic, antipyretic and mild anti-inflammatory properties. It inhibits prostaglandin synthesis, especially in the Central Nervous System. Paracetamol does not inhibit chronic inflammatory reactions.
Caffeine acts on the Central Nervous System, on muscle, including the cardiac muscle and on the kidneys. Its action on the CNS is mainly on the higher centres and produces a condition of wakefulness and increased mental activity.
Codeine is a centrally acting weak analgesic. Codeine exerts its effects through µ opioid receptors, although codeine has a low affinity for these receptors, and its analgesic effect is due to its conversion to morphine. Codeine, particularly in combination with other analgesics such as paracetamol, has been shown to be effective in acute nociceptive pain.
Paracetamol is rapidly absorbed from the upper gastrointestinal tract after oral administration with the small intestine being an important site of absorption. Paracetamol is satisfactorily absorbed from the rectum, but with greater variation than following oral administration.
Peak blood levels of 15-20 micrograms per ml after normal 1 g doses of paracetamol occur within 30-60 minutes depending on dosage form. It is rapidly distributed throughout the body and is primarily metabolised in the liver with excretion via the kidney. Elimination half-life is about 2 hours after reaching a peak following a 1 g oral dose.
Caffeine is absorbed readily after oral administration, but absorption from the gastrointestinal tract may be erratic. There is little evidence of accumulation in any particular tissue.
Caffeine passes readily into the Central Nervous System and into saliva; concentrations have also been detected in breast milk. Caffeine is metabolised almost completely and is excreted via the kidney. Caffeine has a plasma half- life of approximately 3.5 hours and peak plasma concentrations may occur some 50-75 minutes after oral administration.
Codeine Phosphate is absorbed from the gastrointestinal tract. Ingestion of Codeine Phosphate produces peak plasma concentrations in approximately 1 hour. Codeine is metabolised in the liver and the metabolites are excreted almost entirely by the kidney, largely as inactive forms. The half-life of Codeine in plasma is 2-4 hours.
Preclinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction.
