Recommendations of an FDA internal working group on acetaminophen hepatotoxicity have the potential to make a big impact on companies that sell products containing the ingredient. An advisory panel meeting is slated in June to help guide FDA on what actions, if any, to take to reduce risks to patients and consumers.
In the report released May 27 as part of background materials for the meeting, the group recommends eliminating products that combine acetaminophen and other active ingredients, reducing the maximum available OTC dose, and limiting OTC package size, among others. (For a summary and FDA's drug center's overview of the options, skip to page 268 of the PDF).
Manufacturers stand to incur huge costs and reduced revenue opportunities if the agency follows all of the recommendations. Certain products and sizes would come off the market, firms would have to redesign labeling and packaging, and they could incur extensive reformulation costs and potentially even need to conduct new efficacy studies on the lower maximum doses.
For a couple of examples, Johnson & Johnson's Extra Strength products under the Tylenol line would no longer be allowed OTC, because they exceed to proposed new dosage per tablet max. And line extensions containing acetaminophen in lines like Wyeth's Robitussin and P&G's Nyquil would be eliminated as well.

At the meeting in June, FDA's Nonprescription Drugs, Drug Safety and Risk Management and Anesthetic and Life Support Drugs advisory committees will review the recommendations among strategies for reducing liver toxicity risk to patients and consumers using prescription and/or OTC acetaminophen.
