Safe Dosage of Acetaminophen. Acetaminophen is a very safe drug only if it is used within therapeutic doses. The safe dose is 3 grams per day and the maximum daily dose is 4g per day for adults. However, the elderly who tend to have a lower body weight than younger adults should not exceed the safe dose.
Current recommendations advise taking no more than 4,000 milligrams of acetaminophen a day. McNeil's new label will recommend taking no more than 3,000 milligrams of acetaminophen daily. Each Extra Strength Tylenol pill is 500 milligrams; the regular strength formulation contains 325 milligrams per pill. Last January the FDA asked makers of prescription drugs to use no more than 325 milligrams of acetaminophen in any combination product.
