the suggested maximum acetaminophen dosage for adult was 4g/day. Recently, the practice is to counsel patient not to take more than 3g/day. Do not take alcohol while taking acetaminophen, since it will decrease the metabolism of the toxic metabolite. I think there is warning on the product label that if a patient has impaired liver function, he/she should ask a doctor before taking these products.
I never heard of that FDA want to withdraw acetaminophen from the market because of the potential hepatotoxicity. As long as you take it correctly and follow the packaging directions it is quite safe. Yes, for OTC drugs it is easier to over dose, but like the pediatric cough&cold products withdraw last year, it will not be completely withdraw, but just a product label change.
