Acetaminophen OD More Deadly if Taken in Stages

Those who ingested more than 4,000 mg of acetaminophen in a single day spread out over more than one time point had a significantly higher mortality rate compared with those who overdosed at a single time point (37.3% versus 27.8%, P=0.025), according to Kenneth Simpson, MD, of the University of Edinburgh in Scotland, and colleagues.

The cohort analysis included 663 patients admitted with acetaminophen-induced severe liver injury from November 1992 through October 2008. About one-quarter (24.3%) overdosed in a staggered fashion, defined as taking at least two excessive doses separated by more than eight hours and adding up to more than 4,000 milligrams in one day. The rest of the patients ingested that much at a single time point.

Most of the patients who had a staggered overdose (58.2%) said that pain relief was the reason they repeatedly took an excessive dose. Another 34.3% said it was a suicide attempt.
