Posology and method of administration
Adults and the elderly: 5 – 10 ml three to four times a day. Dosage should be reduced in
elderly or debilitated patients.
Children aged less than 12 years: Codeine is contraindicated in children below the age of 12
years (see sections 4.3).
Children aged 12 years to 18 years: Codeine is not recommended for use in children aged 12
years to 18 years with compromised respiratory function (see section 4.4)
Hypersensitivity to codeine or to any of the excipients listed in section 6.1
Ventilatory failure condition may be exacerbated.
Liver disease: drug may accumulate
In women during breastfeeding (see section 4.6)
In patients for whom it is known they are CYP2D6 ultra-rapid metabolisers
In children below the age of 12 years due to an increased risk of developing serious and
life threatening adverse reactions.
Special warnings and precautions for use
Geriatric patients should be supervised while on this medication, and consideration of
reduced dosage should be based on response. Codeine should only be used with
caution in patients with kidney or liver impairment. Care should be taken in patients
with asthma, hypothyroidism, and in patients with a history of drug abuse. Tolerance
and dependency may occur with prolonged use.
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 therapeutic 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
3.4% to 6.5%
1.2% to 2%
3.6% to 6.5%
The leaflet will state, under “Pregnancy and breast-feeding”: Do not take
codeine while you are breastfeeding. Codeine and morphine passes into breast
Patients with rare hereditary problems of fructose intolerance, glucosegalactose malabsorption or sucrase-isomaltase insufficiency should not take
It contains 4 of sucrose per 5ml. To be taken into account in people with
diabetes mellitus. If you have been told by your doctor that you have an
intolerance to some sugars, contact your doctor before taking this medicine.
This medicinal product contains 2% vol% ethanol (alcohol) i.e. up to 156 mg
per 10 ml dose, equivalent to 4 ml of beer or 1.6 ml of wine per 10 ml dose.
Harmful for those suffering from alcoholism. To be taken into account in
pregnant or breast-feeding women, children and high risk groups such as
patient with liver disease or epilepsy.
This product contains sunset yellow which may cause allergic reaction.
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
Interaction with other medicinal products and other forms of interaction
CNS depressants, anticholinergics, hydroxyzine and methadone – concurrent use of these
medicines may result in potentiation of effects and hypotensive effects and CNS depressant
effects may be increased; levallorphan is a morphine antagonist; the respiratory effects of
neuromuscular blocking agents may be addictive to the central respiratory effects of the opioid
analgesics; metoclopramide and codeine have opposing effects on gastro – intestinal activity;
codeine causes delayed absorption of mexiletine; the effects of hypnotics and sedatives may be
potentiated by codeine; hypertensive crisis may be caused by concurrent use of codeine and
monoamine – oxidase inhibitors.
Fertility, pregnancy and lactation
Risk – benefit must be considered before using codeine during pregnancy. Codeine crosses the
placenta and is excreted in small amounts in breast milk.
As with all medications caution should be exercised during pregnancy, especially in the third
trimester when codeine may depress respiration in the neonate. Regular use during pregnancy
may cause physical dependency in the foetus, depression of neonatal respiration, withdrawal
effects in the neonate. Teratogenic effects in humans have not been documented but controlled
studies have not been done. There is a risk of gastric stasis in the mother during labour which
may lead to inhalation pneumonia.
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 ultrarapid 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.
If symptoms of opioid toxicity develop in either the mother or the infant, then all codeine
containing medicines should be stopped and alternative nonopioid analgesics prescribed. In
severe cases consideration should be given to prescribing naloxone to reverse these effects.
Effects on ability to drive and use machines
Codeine may cause drowsiness. Patients receiving this medication should not drive or operate
machinery unless it has been shown not to affect mental or physical ability.
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 prescribing 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:
o The medicine has been prescribed to treat a medical or dental problem and
o You have taken it according to the instructions given by the prescriber and in the
information provided with the medicine and
o It was not affecting your ability to drive safely
Side effects include tolerance and dependence, dizziness, nausea, constipation, loss of
appetite, flushing of face might occasionally occur, respiratory depression may be
experienced, sputum retention may occur particularly in patients with chronic bronchitis and
In therapeutic doses, codeine is much less liable than morphine to produce adverse effects.
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.yellowcard.mhra.gov.uk.
Respiratory depression, dry mouth, sweating and facial flushing. High doses of Codeine may
produce sedation or excitement, and in children convulsions may occur. Respiratory
depression may be reversed with naloxone using one of the following dose regimens:
0.8 – 2 mg repeated at intervals of two to three minutes to a maximum of 10 mg.
10 micrograms/kg and, if no response, subsequent doses of 100 micrograms/kg.
Subcutaneous or Intramuscular Injection
As for intravenous injection but only if the intravenous route is not feasible. The onset of
action is slower with subcutaneous or intramuscular injection.
Continuous Intravenous Infusion
2 mg diluted in 500 ml of intravenous infusion solution at a rate adjusted according to the
In cases of overdosage supportive therapy is recommended. Gastric lavage should be carried
out and a saline purgative may then be given to reduce absorption from gastro – intestinal
tract. Symptomatic treatment of respiratory embarrassment should be given. If respiration is
seriously depressed intravenous naloxone HCl may be required.
Morphine derivative. Antitussive – suppresses the cough reflex by a direct central action,
probably in the medulla or pons.
Codeine is a centrally acting weak analgesic. Codeine exerts its effect through µ opioid
receptors, although codeine has 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.
Codeine is well absorbed after oral administration. It is metabolised in the
liver to morphine and norcodeine which are both excreted in the urine, partly
as conjugates with glucuronic acid. Protein binding is very low. Half-life is
from 2.5 to 4 hours. Duration of action is approximately 4 hours. Onset of
action after oral administration is 30 to 45 minutes.
Most of the excretion products appear in the urine within 6 hours and up to
86% of the dose is excreted in 24 hours. About 70% of the dose is excreted as
free codeine, 10% as free and conjugated morphine and a further 10% as free
or conjugated norcodeine. Only traces are found in the faeces.
Preclinical safety data
There are no preclinical data of relevance to the prescriber which are
additional to those already included in other sections.
