On average, more than 150 Americans die each year from accidentally taking too much acetaminophen, the active ingredient in Tylenol, and tens of thousands more go to emergency rooms or are hospitalized with liver damage associated with the drug, according to government data. About the same number use acetaminophen to commit suicides each year. 

I almost died once from too much Tylenol. Great presentation and database from @a_l@lenagroeger@propublicahttp://t.co/7h4aE6hAmX

But it’s still unclear exactly how many people are harmed by acetaminophen overdoses. Although drug manufacturers are required to report adverse events to the FDA, they don't hear of every case. Hospital and death-certificate data also have problems — for example, the cause of liver failure might not be correctly diagnosed.

We are interested in hearing from people who have experienced acetaminophen poisoning or whose loved ones have suffered this problem. All information will be kept confidential with ProPublica reporters. However, you may also wish to file a report directly with the FDA and can download a consumer report form here.
