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. The hepatotoxicity occurring with acetaminophen use typically correlates with high doses of acetaminophen that exceed the recommended maximum dose.[6] This effect may involve the intake of more than one drug product that contains acetaminophen as an ingredient. Liver damage also has been seen in patients with chronic dosing of acetaminophen.
Updates
Major changes to the best practice guidance in this section include 1) enhancement of the definition of a “precaution” to include any condition that might confuse diagnostic accuracy and 2) recommendation to vaccinate during a hospitalization if a patient is not acutely moderately or severely ill.
General Principles
National standards for pediatric vaccination practices have been established and include descriptions of valid contraindications and precautions to vaccination ( 2 ). Persons who administer vaccines should screen patients for contraindications and precautions to the vaccine before each dose of vaccine is administered ( Table 4-1 ).
Contraindications
Contraindications (conditions in a recipient that increases the risk for a serious adverse reaction) to vaccination are conditions under which vaccines should not be administered. Because the majority of contraindications are temporary, vaccinations often can be administered later when the condition leading to a contraindication no longer exists.
Precautions
A precaution is a condition in a recipient that might increase the risk for a serious adverse reaction, might cause diagnostic confusion, or might compromise the ability of the vaccine to produce immunity (e.g., administering measles vaccine to a person with passive immunity to measles from a blood transfusion administered up to 7 months prior) ( 7 ).
Neither Contraindications Nor Precautions
Clinicians or other health-care providers might misperceive certain conditions or circumstances as valid contraindications or precautions to vaccination when they actually do not preclude vaccination ( 2) ( Table 4-2 ). These misperceptions result in missed opportunities to administer recommended vaccines ( 37 ).
