Liver damage from common pain relievers

Another Stupid Science Blog has an entry about the dangers of combining over the counter medicines and causing liver damage.

Acetaminophen poisoning is now the leading cause of liver failure in the United States, and nearly half of those poisonings are the result of accidental overdosing. Accidental overdosing occured in two main ways: exceeding the recommended daily dosage, or taking 2 drugs that both contained acetaminophen. Overdosing occured at dosages as low as 2.5 times the daily recommended dosage over the course of 3 days.
