Overdose of Acetaminophen Chewable Tablets in details

When a dose is taken in higher dose than the recommended doses, it is called Overdose. Overdose always needs a clinical supervision. Any medicine or drug when consumed in Overdose produces untoward side effects on one or various organs in the body. A medicine is excreted in the kidney or metabolized in the liver most of the times. This process goes without any hurdles when taken in normal dose, but when taken in an overdose, the body is not able to metabolize it or send it out properly which causes the effects of anoverdose.

Signs and Symptoms

In acute Acetaminophen Chewable Tablets overdosage, dose-dependent, potentially fatal hepatic necrosis is the most serious adverse effect. Renal tubular necrosis, hypoglycemic coma, and thrombocytopenia may also occur. Plasma Acetaminophen Chewable Tablets levels > 300 mcg/mL at 4 hours after oral ingestion were associated with hepatic damage in 90% of patients; minimal hepatic damage is anticipated if plasma levels at 4 hours are < 150 mcg/mL or < 37.5 mcg/mL at 12 hours after ingestion. 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

If an Acetaminophen Chewable Tablets overdose is suspected, obtain a serum Acetaminophen Chewable Tablets assay as soon as possible, but no sooner than 4 hours following oral ingestion. Obtain liver function studies initially and repeat at 24-hour intervals. Administer the antidote N-acetylcysteine (NAC) as early as possible. As a guide to treatment of acute ingestion, the Acetaminophen Chewable Tablets level can be plotted against time since oral ingestion on a nomogram (Rumack-Matthew). The lower toxic line on the nomogram is equivalent to 150 mcg/mL at 4 hours and 37.5 mcg/mL at 12 hours. If serum level is above the lower line, administer the entire course of NAC treatment. Withhold NAC therapy if the Acetaminophen Chewable Tablets level is below the lower line.
