Oral solution: 5 mL (25 mg) every 6 to 8 hours as needed.
Alternative recommendations (off-label use in US): Reported doses vary; range: 7.5 to 120 mg/day as a single dose or in divided doses (Bolser 2006; Smith 2010); Note: The American College of Chest Physicians does not recommend the routine use of codeine as an antitussive in patients with upper respiratory infections (Bolser 2006).
Pain management (analgesic): Note: These are guidelines and do not represent the maximum doses that may be required in all patients. Doses should be titrated to pain relief/prevention.
Children ≥12 years and Adolescents: Oral: Canadian labeling:
Immediate release (tablet, oral solution): Refer to adult dosing.
Controlled release: Use is not recommended in patients <18 years of age (has not been studied).
Children: Alternative recommendations (off-label use in US): Oral: Immediate release (tablet, oral solution): Initial: 0.5 to 1 mg/kg/dose every 4 hours as needed; maximum: 60 mg/dose (American Pain Society 2008)
Immediate release (tablet, oral solution): Initial: 15 to 60 mg every 4 hours as needed; maximum total daily dose: 360 mg/day; patients with prior opioid exposure may require higher initial doses. Note: The American Pain Society recommends an initial dose of 30 to 60 mg for adults with moderate pain (American Pain Society 2008).
Controlled release: Codeine Contin [Canadian product]: Note: Titrate at intervals of ≥48 hours until adequate analgesia has been achieved. Daily doses >600 mg/day should not be used; patients requiring higher doses should be switched to an opioid approved for use in severe pain. In patients who receive both Codeine Contin and an immediate release or combination codeine product for breakthrough pain, the rescue dose of the immediate release codeine product should be ≤12.5% of the total daily Codeine Contin dose.
Opioid-naive patients: Initial: 50 mg every 12 hours
Conversion from immediate release codeine preparations: Immediate release codeine preparations contain ~75% codeine base. Therefore, patients who are switching from immediate release codeine preparations may be transferred to a ~25% lower total daily dose of Codeine Contin, equally divided into 2 daily doses every 12 hours.

Concerns related to adverse effects:
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
• Constipation: Use may cause or aggravate constipation; chronic use may result in obstructive bowel disease, particularly in those with underlying intestinal motility disorders. May also be problematic in patients with unstable angina and patients post-myocardial infarction. Consider preventative measures (eg, stool softener, increased fiber) to reduce the potential for constipation.
• Hypotension: May cause hypotension; use with caution in patients with hypovolemia, cardiovascular disease (including acute MI), or drugs which may exaggerate hypotensive effects (including phenothiazines or general anesthetics).
• Phenanthrene hypersensitivity: Use with caution in patients with hypersensitivity reactions to other phenanthrene-derivative opioid agonists (hydrocodone, hydromorphone, levorphanol, oxycodone, oxymorphone). The Canadian labeling contraindicates use in patients allergic to other opioids.
• Respiratory depression: May cause dose-related respiratory depression. The risk is increased in elderly patients, debilitated patients, and patients with conditions associated with hypoxia, hypercapnia, or upper airway obstruction.
• Abdominal conditions: May obscure diagnosis or clinical course of patients with acute abdominal conditions.
• Adrenal insufficiency: Use with caution in patients with adrenal insufficiency, including Addison disease. Long-term opioid use may cause secondary hypogonadism, which may lead to sexual dysfunction, infertility, mood disorders, and osteoporosis (Brennan 2013).
• Biliary tract impairment: Use with caution in patients with biliary tract dysfunction, including acute pancreatitis (use is contraindicated in the Canadian labeling); may cause constriction of sphincter of Oddi; may increase amylase/lipase levels.
• CNS depression/coma: Avoid use of codeine in patients with CNS depression or coma as these patients are susceptible to intracranial effects of CO2 retention.
• Drug abuse: Use with caution in patients with a history of drug abuse or acute alcoholism (use is contraindicated in the Canadian labeling); potential for drug dependency exists. Tolerance, psychological and physical dependence may occur with prolonged use.
• Gastrointestinal obstruction: Avoid use in patients with gastrointestinal obstruction, particularly paralytic ileus; chronic use may result in obstructive bowel disease.
• Head trauma: Use with extreme caution in patients with head injury, intracranial lesions, or elevated intracranial pressure (use is contraindicated in the Canadian labeling); exaggerated elevation of ICP may occur. May also interfere with pupillary response and consciousness, thereby, affecting neurologic examination.
• Hepatic impairment: Use with caution in patients with severe hepatic impairment.
• Obesity: Use with caution in patients who are morbidly obese.
• Prostatic hyperplasia/urinary stricture: Use with caution in patients with prostatic hyperplasia and/or urinary stricture.
• Renal impairment: Use with caution in patients with severe renal impairment.
• Respiratory disease: Use with caution in patients with preexisting respiratory compromise (hypoxia), COPD or other obstructive pulmonary disease, and kyphoscoliosis or other skeletal disorder which may alter respiratory function; critical respiratory depression may occur, even at therapeutic dosages.
• Seizure disorders: May induce or aggravate seizures; use with caution in patients with seizure disorders (use is contraindicated in the Canadian labeling).
• Thyroid dysfunction: Use with caution in patients with thyroid dysfunction.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Sedatives: Effects may be potentiated when used with other sedative drugs or ethanol.
• CYP2D6 “ultrarapid metabolizers”: Use caution in patients with two or more copies of the variant CYP2D6*2 allele; may have extensive conversion to morphine and thus increased opioid-mediated effects. Avoid the use of codeine in these patients; consider alternative analgesics such as morphine or a nonopioid agent (Crews 2012). The occurrence of this phenotype is seen in 0.5% to 1% of Chinese and Japanese, 0.5% to 1% of Hispanics, 1% to 10% of Caucasians, 3% of African-Americans, and 16% to 28% of North Africans, Ethiopians, and Arabs.
• Debilitated patients: Use with caution in debilitated patients; there is a greater potential for critical respiratory depression, even at therapeutic dosages.
• Elderly: Use with caution in the elderly; may be more sensitive to adverse effects. Consider decreasing the initial dose.
• Neonates: Neonatal withdrawal syndrome: After chronic maternal exposure to opioids, neonatal withdrawal syndrome may occur in the newborn; monitor neonate closely. Signs and symptoms include irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. Onset, duration and severity depend on the drug used, duration of use, maternal dose, and rate of drug elimination by the newborn. Opioid withdrawal syndrome in the neonate, unlike in adults, may be life-threatening and should be treated according to protocols developed by neonatology experts.
• Pediatric: [US Boxed Warning]: Respiratory depression and death have occurred in children who received codeine following tonsillectomy and/or adenoidectomy and were found to have evidence of being ultra-rapid metabolizers of codeine due to a CYP2D6 polymorphism. Deaths have also occurred in nursing infants after being exposed to high concentrations of morphine because the mothers were ultra-rapid metabolizers. Use is contraindicated in the postoperative pain management of children who have undergone tonsillectomy and/or adenoidectomy. The Canadian labeling contraindicates use in children <12 years of age.
Dosage form specific issues:
• Sulfites: Some preparations contain sulfites which may cause allergic reactions.
• Abuse/misuse/diversion: Healthcare provider should be alert to the potential for abuse, misuse, and diversion.
• Withdrawal: Concurrent use of agonist/antagonist analgesics may precipitate withdrawal symptoms and/or reduced analgesic efficacy in patients following prolonged therapy with mu opioid agonists. Abrupt discontinuation following prolonged use may also lead to withdrawal symptoms.
Pain relief, respiratory and mental status, blood pressure, heart rate; signs or symptoms of hypogonadism or hypoadrenalism (Brennan 2013)
Pregnancy Risk Factor
Adverse events have been observed in animal reproduction studies. Opioid analgesics cross the placenta. In humans, birth defects (including some heart defects) have been associated with maternal use of codeine during the first trimester of pregnancy (Broussard 2011). If chronic opioid exposure occurs in pregnancy, adverse events in the newborn (including withdrawal) may occur; monitoring of the neonate is recommended. The minimum effective dose should be used if opioids are needed (Chou 2009). Neonatal abstinence syndrome following opioid exposure may present with autonomic (eg, fever, temperature instability), gastrointestinal (eg, diarrhea, vomiting, poor feeding/weight gain), or neurologic (eg, high pitched crying, increased muscle tone, irritability, seizure, tremor) symptoms (Dow 2012; Hudak 2012).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience fatigue or sweating a lot. Have patient report immediately to prescriber severe dizziness, passing out, angina, tachycardia, trouble breathing, slow breathing, shallow breathing, illogical thinking, arrhythmia, hallucinations, mood changes, seizures, severe abdominal pain, severe headache, difficult urination, tremors, vision changes, severe nausea, vomiting, severe constipation, or loss of strength and energy (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
