What is the maximum dose of Tylenol?

Tylenol lists its recommended and maximum dosages differently, depending on strength of the acetaminophen dose in each capsule. Acetaminophen is the active ingredient in Tylenol, and its strength in the capsules is measured in milligrams.

For adults taking a regular strength dose (325 mg), Tylenol recommends a maximum of two tablets every four to six hours, and no more than 10 every 24 hours. The maximum recommended dosage for Extra Strength Tylenol (500 mg) is two caplets every six hours, and no more than six every 24 hours, and for Tylenol Arthritis Pain (650mg), it is two every eight hours and no more than six in 24 hours. In case of an overdose, individuals should call 911 or a poison control center.
