We sure need a new pain medicine without the baggage of NSAIDs or the stigma of opioids. Johnson & Johnson thinks it might have an answer - a derivative of Tylenol without the associated liver toxicity. But does it treat pain? Not very well.
liver toxicity
Medline Industries, a manufacturer of acetaminophen isn't looking too good right now. The company's 325 mg acetaminophen ( the generic name of Tylenol) turned out to be 500 mg instead. Although this seems like a non-story, it is not. Acetaminophen is quite toxic at doses that are not that far from the normal daily dose. Cough syrups, and other OTC products can compounds the risk.
