Boxed Warning:
Warning: 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 ( see warnings ). 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.
Indications and Usage:
Indications and usage acetaminophen and codeine phosphate tablets are indicated for the relief of mild to moderately severe pain.
Warnings:
Warnings 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. the excessive intake of acetaminophen may be intentional to cause self-harm or unintentional as patients attempt to obtain more pain relief or unknowingly take other acetaminophen-containing products. the risk of acute liver failure is higher in individuals with underlying liver disease and in individuals who ingest alcohol while taking acetaminophen. instruct patients to look for acetaminophen or apap on package labels and not to use more than one product that contains acetaminophen. instruct patients to seek medical attention immediately upon ingestion of more than 4000 milligrams of acetaminophen per day, even if they feel well. serious skin reactions rar

Dosage and Administration:
Dosage and administration dosage should be adjusted according to severity of pain and response of the patient. the usual adult dosage is: single doses (range) maximum 24-hour dose codeine phosphate 15 mg to 60 mg 360 mg acetaminophen 300 mg to 1000 mg 4000 mg 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.
Contraindications:
Contraindications codeine-containing products are contraindicated for postoperative pain management in children who have undergone tonsillectomy and/or adenoidectomy. this product should not be administered to patients who have previously exhibited hypersensitivity to codeine or acetaminophen.
Adverse Reactions:
Adverse reactions 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.
Overdosage:
Overdosage following an acute overdosage, toxicity may result from codeine or acetaminophen. signs and symptoms toxicity from codeine poisoning includes the opioid triad of pinpoint pupils, depression of respiration, and loss of consciousness. convulsions may occur. in acetaminophen overdosage, dose-dependent, potentially fatal hepatic necrosis is the most serious adverse effect. renal tubular necrosis, hypoglycemic coma and coagulation defects may also occur. early symptoms following a potentially hepatotoxic overdose may include nausea, vomiting, diaphoresis and general malaise. clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion. treatment a single or multiple drug overdose with acetaminophen and codeine is a potentially lethal polydrug overdose, and consultation with a regional poison control center is recommended. immediate treatment includes support of cardiorespiratory function and measures to reduce drug absorption. oxygen, intravenous fluids, vasopressors, and other supportive measures should be employed as indicated. assisted or controlled ventilation should also be considered. for respiratory depression due to overdosage or unusual sensitivity to codeine, parenteral naloxone is a specific and effective antagonist. gastric decontamination with activated charcoal should be administered just prior to n-acetylcysteine (nac) to decrease systemic absorption if acetaminophen ingestion is known or suspected to have occurred within a few hours of presentation. serum acetaminophen levels should be obtained immediately if the patient presents 4 or more hours after ingestion to assess potential risk of hepatotoxicity; acetaminophen levels drawn less than 4 hours post-ingestion may be misleading. to obtain the best possible outcome, nac should be administered as soon as possible where impending or evolving liver injury is suspected. intravenous nac may be administered when circumstances preclude oral administration. vigorous supportive therapy is required in severe intoxication. procedures to limit the continuing absorption of the drug must be readily performed since the hepatic injury is dose-dependent and occurs early in the course of intoxication.
dependence:
Drug abuse and dependence controlled substance acetaminophen and codeine phosphate tablets are classified as a schedule iii controlled substance. abuse and dependence codeine can produce drug dependence of the morphine type and, therefore, has the potential for being abused. psychological dependence, physical dependence, and tolerance may develop upon repeated administration and it should be prescribed and administered with the same degree of caution appropriate to the use of other oral narcotic medications.

Clinical Pharmacology:
Clinical pharmacology this product combines the analgesic effects of a centrally acting analgesic, codeine, with a peripherally acting analgesic, acetaminophen. pharmacokinetics the behavior of the individual components is described below. codeine â codeine is rapidly absorbed from the gastrointestinal tract. it is rapidly distributed from the intravascular spaces to the various body tissues, with preferential uptake by parenchymatous organs such as the liver, spleen and kidney. codeine crosses the blood-brain barrier, and is found in fetal tissue and breast milk. the plasma concentration does not correlate with brain concentration or relief of pain; however, codeine is not bound to plasma proteins and does not accumulate in body tissues. the plasma half-life is about 2.9 hours. the elimination of codeine is primarily via the kidneys, and about 90% of an oral dose is excreted by the kidneys within 24 hours of dosing. the urinary secretion products consist of free and glucuronide c
