Therapeutic dose of acetaminophen is 15 mg/kg q6h prn. That dose of 4g/day ==> 1g/dose. 1000mg/(15mg/kg) = 66.67kg == 145lb.
That’s the minimum weight for that acetaminophen dosing. If you’re under that weight, you can consider the reduced dose. If you’re over 145lb, no need to worry. And honestly, I think I’m the only one who actually doses this stuff q6h anyway. I think most people end up doing TID dosing because that allows uninterrupted sleep.
