It is also considering (but has not enacted) reducing the maximum daily dose from 4 g (possibly to 3,250 mg), banning acetaminophen-narcotic combination products, and changing the current maximum single dose of 1 g to prescription status, making 650 mg the highest recommended nonprescription dose. We review the epidemiology, toxicology, and management of acetaminophen overdose and steps the FDA and physicians can take to prevent it. ER -
