Pharmacists and nurses need to emphasize the maximum dose permitted daily. Patients also need to understand how to look for acetaminophen in various medications they take and how to calculate the dose they receive when they combine products. Pharmacists need to perform medication reconciliation to look for drug interactions, as well as verify that there are not too many acetaminophen-containing drugs in the regimen. If there are concerns, the pharmacist should report them to the nurse and physician.

How does acetaminophen affect the liver?

Acetaminophen is responsible for an estimated 500 deaths and 50000 emergency department visits in the United States each year.[9] It is the most common drug-related cause of acute liver failure. The mechanism of hepatic injury is due to the drug metabolism properties of acetaminophen.[10] Following therapeutic concentrations of oral acetaminophen, 60% to 90% of the drug gets metabolized in the liver to glucuronic acid- and sulfate-conjugate metabolites. A smaller fraction (approximately 5% to 15%) undergoes metabolism by the cytochrome P450 system (CYP450). Metabolism primarily via CYP2E1 results in the formation of the toxic intermediate N-acetyl-p-benzoquinone imine (NAPQI).  Normally, NAPQI is neutralized by glutathione to nontoxic metabolites. However, with excessive doses of acetaminophen, the normal phase II drug metabolism pathways become depleted, and the CYP450 pathway metabolizes a higher portion of the acetaminophen taken, resulting in high concentrations of NAPQI formation, and the limited glutathione stores can become depleted. Without glutathione, NAPQI concentrations build-up, and NAPQI, as a reactive intermediate, can react with cellular macromolecules, proteins, lipids, and nucleic acids. This phenomenon can lead to centrilobular (Zone 3) hepatic injury and hepatocellular death. There can also be nephrotoxicity.

What is the best antidote for acetaminophen overdose?

The only approved antidote for acetaminophen overdose and toxicity is N-acetylcysteine (NAC).[11] NAC is a precursor to glutathione synthesis and helps to restore the intracellular stores of glutathione to neutralize the NAPQI compound, and it can inactivate NAPQI directly. N-acetyl cysteine can be administered orally or by IV. IV N-acetyl cysteine is typically preferred because vomiting is common with acetaminophen overdose. It is effective when administered within the first few hours (up to 8 to 10 hours) of a toxic ingestion of acetaminophen. N-acetyl cysteine administration has a 20-hour IV protocol or 72-hour oral protocol, and the clinician must monitor the AST/ALT during treatment.[12] One important thing to keep in mind is that most patients do not have symptoms in the first few hours of ingestion of toxic doses of acetaminophen and may only have abdominal pain and nausea as symptoms for the first 12 to 24 hours. Between 24 and 72 hours, these symptoms may dissipate, although AST/ALT concentrations may be abnormal. Patients who present more than 24 hours following ingestion of toxic doses of acetaminophen may have symptoms such as nausea, vomiting, jaundice, abdominal pain, and hypotension. These patients may require airway management, intravenous fluids, vasopressors, hemodialysis, or management of cerebral edema or other symptoms as they arise.

Is acetaminophen a contraindication?

Contraindications to the use of acetaminophen include hypersensitivity to acetaminophen, severe hepatic impairment, or severe active hepatic disease. However, there is a general debate among experts whether hepatic impairment is truly a limiting factor, as it would likely be associated with decreased production of the toxic metabolite, N-acetyl-p-benzoquinoneimine (NAPQI).

Does acetaminophen cross the placental barrier?

Acetamino phen can cross the placental barrier, but there is no evidence of increased teratogenic effects due to the use of normal doses of acetaminophen during pregnancy.[8] Acetaminophen also is excreted into breast milk, but there have not been many observations of adverse reactions in nursing infants.

Does acetaminophen cause liver failure?

Acetaminophen use has been linked to liver failure and sometimes has led to liver transplant or death.

Liver damage also has been seen in patients with chronic dosing of acetaminophen.

How long does it take for acetaminophen to raise serum levels?

Chronic therapy with acetaminophen in doses of 4 grams daily has been found to lead to transient elevations in serum aminotransferase levels in a proportion of subjects, generally starting after 3 to 7 days, and with peak values rising above 3-fold elevated in 39% of persons. These elevations are generally asymptomatic and resolve rapidly with stopping therapy or reducing the dosage, and in some instances resolve even with continuation at full dose (Case 1).

How does acetaminophen cause hepatoxicity?

The injury is due to a direct, toxic effect of the high doses of acetaminophen. Acetaminophen hepatotoxicity most commonly arises after a suicide attempt using more than 7.5 grams (generally more than 15 grams) as a single overdose (Case 2). Hepatic injury generally starts 24 to 72 hours after the ingestion with marked elevations in serum ALTand AST(often to above 2000 U/L), followed at 48 to 96 hours by clinical symptoms: jaundice, confusion, hepatic failure and in some instances death. Evidence of renal insufficiency is also common. Serum aminotransferase levels fall promptly and recovery is rapid if the injury is not too severe. Similar injury can occur with high therapeutic or supratherapeutic doses of acetaminophen given over several days for treatment of pain and not as a purposeful suicidal overdose (Case 3). This form of acetaminophen hepatotoxicity is referred to as accidental or unintentional overdose, and usually occurs in patients who have been fasting, or are critically ill with a concurrent illness, alcoholism or malnutrition, or have preexisting chronic liver disease. Some cases of unintentional overdose occur in patients taking acetaminophen in combinations with controlled substances (oxycodone, codeine), who take more than recommended amounts over several days in attempts to control pain or withdrawal symptoms. Instances of unintentional overdose in children are often due to errors in calculating the correct dosage or use of adult sized tablets instead of child or infant formulations. Because acetaminophen is present in many products, both by prescription and over-the-counter, another problem occurs when a patient ingests full or high doses of several products unaware that several contain acetaminophen.

How much acetaminophen is in a single overdose?

Is acetaminophen a hepatotoxic drug?

Acetaminophen is a widely used nonprescription analgesic and antipyretic medication for mild-to-moderate pain and fever.

Does acetaminophen cause liver damage?

While acetaminophen has few side effects when used in therapeutic doses, recent reports suggest that its standard use can result in severe hypersensitivity reactions including Stevens Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Both of these syndromes can be life-threatening and both may be accompanied by evidence of liver injury. However, the hepatic involvement is usually mild and marked only by asymptomatic mild-to-moderate elevations in serum aminotransferase levels.

Who has the responsibility to determine the maximum acetaminophen dose?

Does acetaminophen inhibit the COX pathway?

It may be that acetaminophen inhibits the COX pathway in the central nervous system but not peripheral tissues. Additionally, acetaminophen does not appear to bind to the active site of either the COX-1 or COX-2 enzyme, instead of reducing the activity of COX by a different mechanism.
