It is unlikely that any single tablet of acetaminophen would be fatal.  I would recommend a dose of 1/2 of a maximum daily dose for an adult, as a starting point.  It is also recommended that you tell your doctor about any other medications that you are taking, in order to determine if they have any interaction<|im_end|>
