In general, acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) is well-tolerated when administered in therapeutic doses.
Alcoholic patients may develop hepatotoxicity after even modest doses of acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) In healthy patients, approximately 15 grams of acetaminophen is necessary to deplete liver glutathione stores by 70% in a 70 kg person. However, hepatotoxicity has been reported following smaller doses. Glutathione concentrations may be repleted by the antidote N-acetylcysteine. One case report has suggested that hypothermia may also be beneficial in decreasing liver damage during overdose.
In a recent retrospective study of 306 patients admitted for acetaminophen overdose, 6.9% had severe liver injury but all recovered. None of the 306 patients died.
A 19-year-old female developed hepatotoxicity, reactive plasmacytosis and agranulocytosis followed by a leukemoid reaction after acute acetaminophen toxicity.
Hepatic side effects including severe and sometimes fatal dose dependent hepatitis have been reported in alcoholic patients. Hepatotoxicity has been increased during fasting. Several cases of hepatotoxicity from chronic acetaminophen therapy at therapeutic doses have also been reported despite a lack of risk factors for toxicity.
Gastrointestinal side effects have included nausea (34%) and vomiting (15%). Cases of acute pancreatitis have been reported rarely.
One study has suggested that acetaminophen may precipitate acute biliary pain and cholestasis. The mechanism of this effect may be related to inhibition of prostaglandin and alterations in the regulation of the sphincter of Oddi.
Renal side effects are rare and have included acute renal failure, acute tubular necrosis, and interstitial nephritis. Adverse renal effects are most often observed after overdose, after chronic abuse (often with multiple analgesics), or in association with acetaminophen-related hepatotoxicity.
Acute tubular necrosis usually occurs in conjunction with liver failure, but has been observed as an isolated finding in rare cases. A possible increase in the risk of renal cell carcinoma has been associated with chronic acetaminophen use as well.
One case-control study of patients with end-stage renal disease suggested that long term consumption of acetaminophen may significantly increase the risk of end-stage renal disease particularly in patients taking more than two pills per day.
However, a recent cohort study of analgesia use of initially healthy men concluded that moderate use of analgesics including acetaminophen was not associated with increased risk of renal disease.
Hypersensitivity side effects including anaphylaxis and fixed drug eruptions have been reported rarely in association with acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) use.
Hematologic side effects including rare cases of thrombocytopenia associated with acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) have been reported. Acute thrombocytopenia has also been reported as having been caused by sensitivity to acetaminophen glucuronide, the major metabolite of acetaminophen. Methemoglobinemia with resulting cyanosis has been observed in the setting of acute overdose.
Dermatologic side effects including erythematous skin rashes associated with acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) have been reported, but are rare. Acetaminophen associated bullous erythema and purpura fulminans have been reported. One case of toxic epidermal necrolysis associated with acetaminophen administered to a pediatric patient has been reported. Dermatologic side effects associated with IV acetaminophen have included infusion site pain and peripheral edema.
Very rare potentially fatal skin reactions: Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and acute generalized exanthematous pustulosis (AGEP).
Respiratory side effects have included dyspnea and a case of acetaminophen-induced eosinophilic pneumonia.
Two cases hypotension have been reported following the administration of acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) Both patients experienced significant decreases in blood pressure. One of the two patients required pressor agents to maintain adequate mean arterial pressures. Neither episode was associated with symptoms of anaphylaxis. Neither patient was rechallenged after resolution of the initial episode.
Cardiovascular side effects including hypertension and hypotension have been reported following the administration of acetaminophen.
In the case of metabolic acidosis, causality is uncertain as more than one drug was ingested. The case of metabolic acidosis followed the ingestion of 75 grams of acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) 1.95 grams of aspirin, and a small amount of a liquid household cleaner. The patient also had a history of seizures which the authors reported may have contributed to an increased lactate level indicative of metabolic acidosis.
Metabolic side effects have included hypokalemia. Metabolic side effects including metabolic acidosis have been reported following a massive overdose of acetaminophen.
Nervous system side effects associated with IV acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) have included headache (10%), insomnia (7%), and fatigue.
Musculoskeletal side effects associated with acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) IV have included muscle spasms and trismus.
Psychiatric side effects associated with acetaminophen (the active ingredient contained in Childrens Panadol 1 - 5 Years) IV have included anxiety.
