I can't understand why you didn't provide a link. Here it is: 
http://www.fda.gov/bbs/topics/enforce/2002/ENF00775.html (scroll down to Drugs -- 
Class III, or do page search on Tylenol).

I wonder if the problem was that the dosing cup units were inconsistent with the 
instructions on the bottle or package. Obviously, if that's so, the correction should 
be to the instructions, not to the already metric dosing cup. That kind of 
inconsistency is mentioned in the article (dated October 1994) at 
http://www.fda.gov/fdac/reprints/drugdose.html. Here's the relevant paragraph:

FDA Action
     Soon after FDA received the report of the acetaminophen dosing cup
error, the agency learned of similar incidents with other acetaminophen drug
products and pediatric cough/cold preparations. As a result, FDA undertook a
survey of over-the-counter liquid medication makers to ensure that the
labeling of these products is compatible with their dose cups and that the
cups are easily readable. FDA's action prompted eight drug firms to recall
nationwide over 980,000 bottles of oral medications and their accompanying
dosage delivery devices because the devices were not consistent with the
products' labeled directions.

An earlier paragraph refers to an overdose resulting from instructions specifying 
teaspoons and a dosing cup calibrated in tablespoons. Obviously, the only safe answer 
is to enforce the use of SI throughout.
