it does not take many acetaminophen (tylenol) pills to cause serious liver damage. the absolute maximum daily dose of acetaminophen for adults is 4000mg. people should avoid taking more than the maximum daily dose of acetaminophen in order to avoid permanent liver damage. if your friend took acetaminophen on purpose to hurt him- or herself i hope s/he received appropriate psychological help. acetaminophen overdose is not an effective way to commit suicide. it can possibly cause a person much pain and suffering however. wishing you and your friend all the best.
someone i know took too many tylenol. how many tylenol would you have to take to do permanent damage to vital organs?
