I have been anti-Tylenol for almost 14 years. I have seen what excessive use of Tylenol can do to the liver. I have seen accidental over-ingestion that led to acute liver failure. I have watched many die after intentional overuse of Tylenol products to end their life. Acetaminophen, the active ingredient in Tylenol, is dangerous. I have long said “if the FDA had to approve Tylenol today, they would surely say no and it would not be on the market”.
