Recently ProPublica and This American Life (TAL) released the results of an investigation into acetaminophen, the active ingredient in Tylenol. TAL devoted an entire episode to the issue, and ProPublica has published several stories on acetaminophen’s toxicity, how it can cause harm, and how it is regulated.
The investigation summarizes the key “Takeaways” as follows:
- 150 Americans die per year from accidental acetaminophen overdoses
- The safety margin (safe dose vs. toxic dose) with acetaminophen is small
