Peter Rost (doctor)

Peter Rost is an American former drug marketing executive who is most known for taking public stances critical of the pharmaceutical industry as an "insider" and whistleblower. He sued his last two pharmaceutical employers, Wyeth and Pfizer, the latter of which fired him in 2005. At Wyeth, he uncovered tax evasion practices, and after informing senior company executives, was transferred from Sweden to a post in New Jersey. Rost sued the company, saying that the transfer was a retaliatory demotion, though the company said it was a promotion. Rost settled with Wyeth for an undisclosed amount in 2003. At Pfizer, Rost filed a qui tam suit disclosing off-label marketing of Genotropin at Pharmacia prior to its purchase by Pfizer. The U.S. Department of Justice declined to join in Rost's suit as the marketing violations had already been disclosed to the Department by Pfizer. Rost was eventually fired by Pfizer, and sued for wrongful dismissal. In 2013 Pfizer, the Department of Justice, and Rost settled on undisclosed terms. Rost then worked as a public speaker, author, and litigation consultant.
