In January 1999, the FDA recommended that Trovan be prescribed only for patients in nursing homes or hospitals suffering from life-threatening conditions. (Compl. P 223.) That following June, the FDA issued a public health advisory on liver toxicity associated with oral and intravenous Trovan following post-marketing reports of acute liver failure strongly associated with the drug. (Compl. P 224.) The FDA announced that it received reports of more than 100 cases where Trovan patients exhibited clinically symptomatic liver toxicity and advised physicians to use Trovan only for patients who met certain criteria. (Compl. P 224-25.) In addition, Pfizer agreed to limit distribution of Trovan to hospitals and long term nursing facilities. (Compl. P 224.) Further, the European Union's Committee for Proprietary Medicinal Products suspended all sales of Trovan in part due to results from the Kano tests. (Compl. PP 221-22.)
