Repeated Use of Acetaminophen Can Be Fatal

That would be, for example, Tylenol - a medication given to kids. And this has been around for, like, ever.

Imagine what they will find with weight loss drugs. Too late. See above.

Repeated doses of slightly too much acetaminophen (known as paracetamol in the United Kingdom and elsewhere in Europe) can be fatal, according to the results of a large, single-center cohort study published online November 22 in the British Journal of Clinical Pharmacology.

"On admission, these staggered overdose patients were more likely to have liver and brain problems, require kidney dialysis or help with breathing and were at a greater risk of dying than people who had taken single overdoses," senior author Kenneth J. Simpson, MBChB (Hons), MD, FRCP (Edin), from the University of Edinburgh and Scottish Liver Transplant Unit in the United Kingdom, said in a news release.

"They haven't taken the sort of single-moment, one-off massive overdoses taken by people who try to commit suicide, but over time the damage builds up, and the effect can be fatal," he adds.

In the United Kingdom, acetaminophen hepatotoxicity is the leading cause of acute liver failure (ALF). However, the effect of a staggered overdose pattern or delayed hospital presentation on mortality or need for emergency liver transplantation was previously unknown.

They will find bad stuff, too.
