BACKGROUND Acetaminophen was falsely detected in the plasma of a severely jaundiced patient, and a methodologic interference from bilirubin was suspected. METHODS Acetaminophen was measured by an enzymatic method (GDS Diagnostics). The putative bilirubin interference was investigated in 12 hyperbilirubinemic specimens and in bilirubin linearity calibrators. The analytical method was modified ...

QUESTION I frequently suggest to parents to use acetaminophen to treat their children's fever and pain. Recently, I had a child in my office who presented with a target-lesion skin rash a day after receiving acetaminophen. The rash resolved after 3 days and after stopping administration of acetaminophen. Does acetaminophen carry a risk of adverse events such as this? ANSWER Like any other med...

Acetaminophen is commonly used during pregnancy. Experimental animal studies do not suggest increased malformations after therapeutic use of single-ingredient acetaminophen during pregnancy. Cohort studies in humans in which exposure is prospectively ascertained show no detectable increase in congenital malformation risk associated with single-ingredient acetaminophen use during pregnancy. A ca...

introduction: management of pain in children is often inadequate and numerous clinical practice guidelines and policy statements have been published on the subject of pediatric pain. tonsillectomy is among the most frequent otorhinolaryngologic surgeries, especially in the pediatric age group and after tonsillectomy the patients usually suffer from mild to severe pain for three postoperative da...

Acetaminophen (paracetamol) is the most frequently used analgesic and antipyretic drug available over the counter. At the same time, acetaminophen overdose is the most common cause of acute liver failure and the leading cause of chronic liver damage requiring liver transplantation in developed countries. Acetaminophen overdose causes a multitude of interrelated biochemical reactions in hepatocy...

Acetaminophen-induced hepatotoxicity results from hepatic enzymatic oxidation of acetaminophen to a toxic, electrophilic intermediate. Acetaminophen is ordinarily eliminated after conjugation with glucuronic acid and sulfate to nontoxic derivatives. Cimetidine has been shown to inhibit the hepatic oxidation of a number of drugs and to protect rats from acetaminophen-induced hepatic necrosis. Th...

a positive association between acetaminophen intake and allergic diseases has recently been reported in developed countries with impaired oxidant/antioxidant balance and promotion of atopy as proposed underlying mechanisms. the aim of the study was to explore the relationship between acetaminophen intake and asthma, hay fever, and eczema in the republic of macedonia as a country with acetaminop...

Acetaminophen is cleared primarily by hepatic glucuronidation. Polymorphisms in genes encoding the acetaminophen UDP-glucuronosyltransferase (UGT) enzymes could explain interindividual variability in acetaminophen glucuronidation and variable risk for liver injury after acetaminophen overdose. In this study, human liver bank samples were phenotyped for acetaminophen glucuronidation activity and...

The purpose of this study was to examine whether intracellular metallothionein (MT) protects against acetaminophen hepatotoxicity. MT-I/II knockout (MT-null) and control mice were given acetaminophen (150-500 mg/kg i.p.), and liver injury was assessed 24 h later. MT-null mice were more susceptible than controls to acetaminophen-induced lethality and hepatotoxicity, as evidenced by elevated seru...
