A class action was filed against Bayer AG on behalf of employees of the Brentwood Post Office in Washington , D.C. , and workers at the U.S. Capitol , along with employees of American Media , Inc. in Florida and postal workers in general who alleged they suffered serious adverse effects from taking ciprofloxacin in the aftermath of the anthrax attacks in 2001 . The action alleged Bayer failed to warn class members of the potential side effects of the drug , thereby violating the Pennsylvania Unfair Trade Practices and Consumer Protection Laws . The class action was defeated and the litigation abandoned by the plaintiffs . A similar action was filed in 2003 in New Jersey by four New Jersey postal workers but was withdrawn for lack of grounds , as workers had been informed of the risks of ciprofloxacin when they were given the option of taking the drug
