Maybe not. Tylenol, which is acetaminophen, can cause liver injury. It depends on how much you are taking, if you have liver disease, and if you drink alcohol. If you have no liver disease and don’t drink, the total labeled daily dose for a healthy adult is 3,250 mg, spaced over 24 hours. Your doctor may prescribe as much as 4,000 mg in divided doses. If you take other medicines that have acetaminophen in it, such as sleep or allergy remedies, be sure to include those amounts when figuring the total Tylenol dose.
