Advisory information

CONTRAINDICATIONS SECTION Codeine-containing products are contraindicated for post-operative pain management in children who have undergone tonsillectomy and/or adenoidectomy. Acetaminophen and Codeine Phosphate Tablets should not be administered to patients who have previously exhibited hypersensitivity to codeine or acetaminophen.
Special warnings and precautions
PRECAUTIONS SECTION General Acetaminophen and Codeine Phosphate Tablets should be prescribed with caution in certain special-risk patients, such as the elderly or debilitated, and those with severe impairment of renal or hepatic function, head injuries, elevated intracranial pressure, acute abdominal conditions, hypothyroidism, urethral stricture, Addison's disease, or prostatic hypertrophy.
Adverse reactions
ADVERSE REACTIONS SECTION The most frequently observed adverse reactions include drowsiness, lightheadedness, dizziness, sedation, shortness of breath, nausea and vomiting. These effects seem to be more prominent in ambulatory than in non-ambulatory patients, and some of these adverse reactions may be alleviated if the patient lies down. Other adverse reactions include allergic reactions, euphoria, dysphoria, constipation, abdominal pain, pruritus, rash, thrombocytopenia and agranulocytosis. At higher doses codeine has most of the disadvantages of morphine including respiratory depression.

Usage information

Dosing and administration
DOSAGE & ADMINISTRATION SECTION Dosage should be adjusted according to severity of pain and response of the patient. The usual adult dosage is: Single Doses Maximum Range 24-Hour Dose Codeine Phosphate 15mg to 60mg 360 mg Acetaminophen 300 mg to 1000 mg 4000 mg The usual dose of codeine phosphate in children is 0.5 mg/kg. Doses may be repeated up to every 4 hours. The prescriber must determine the number of tablets per dose, and the maximum number of tablets per 24 hours, based upon the above dosage guidance. This information should be conveyed in the prescription. It should be kept in mind, however, that tolerance to codeine can develop with continued use and that the incidence of untoward effects is dose related. Adult doses of codeine higher than 60 mg fail to give commensurate relief of pain but merely prolong analgesia and are associated with an appreciably increased incidence of undesirable side effects. Equivalently high doses in children would have similar effects.

Warnings BOXED WARNING SECTION WARNING: Death Related to Ultra-Rapid Metabolism of Codeine to Morphine Respiratory depression and death have occurred in children who received codeine following tonsillectomy and/or adenoidectomy and had evidence of being ultra-rapid metabolizers of codeine due to a CYP2D6 polymorphism. Hepatotoxicity Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4000 milligrams per day, and often involve more than one acetaminophen-containing product.
