It depends on your weight too, but normally you shouldn’t exceed 4g of acetaminophen (Tylenol) per day. For instance, 5 generic Vicodin pills would give about 2.5 grams of acetaminophen at once, which gets really close to a toxic level of acetaminophen per day. You should never exceed 4 grams of Tylenol per day because you risk having serious liver damage. Also, it’s not recommended to continue getting close to 4grams of Tylenol each day (about 8 generic Vicodin pills), because in time your liver might suffer consequences.

Liver damage could possibly cause liver failure which is a critical thing, since accidental or intentional acetaminophen overdose is one reason why young people end up needing liver transplants or risk dying.
