Omnicare is a Fortune 500 company based in Cincinnati, Ohio. Omnicare functions primarily as a provider of pharmaceuticals, related consulting and data management services. As of December 31, 2009 the company provided its pharmacy services to skilled nursing, assisted living, and other healthcare facilities comprising approximately 1.4 million beds in 47 U.S. states, the District of Columbia and Canada.
In 2012, the Federal Trade Commission (FTC) sued Omnicare to block its hostile takeover of its rival PharMerica under federal anti-trust law. The FTC alleged that the acquisition would boost drug costs and inflate Medicare expenditures by consolidating the industry and reducing price competition. PharMerica owned 97 long-term-care pharmacies, while Omnicare owned approximately 200. The merger would have given Omnicare a 57% marketshare versus two percent for its nearest, non-PharMerica rival. Because of the FTC opposition, the takeover was terminated.
In November 2009, Omnicare paid $98 million to the federal government to settle five “qui tam” (whistleblower) lawsuits and government charges that the company had paid or solicited a variety of kickbacks. The company admitted no wrongdoing. The charges included allegations that Omicare solicited and received kickbacks from a pharmaceutical manufacturer Johnson & Johnson, in exchange for agreeing to recommend that physicians prescribe Risperdal, a Johnson & Johnson antipsychotic drug, to nursing home patients.
Starting in 2006, healthcare entrepreneur Adam B. Resnick sued Omnicare, a major supplier of drugs to nursing homes, under the False Claims Act, as well as the parties to the company’s illegal kickback schemes. Omnicare allegedly paid kickbacks to nursing home operators in order to secure business, which constitutes Medicare and Medicaid fraud. Omnicare allegedly had paid $50 million to the owners (Leonard Grunstein and Rubin Schron) of the Mariner Health Care Inc. and SavaSeniorCare Administrative Services LLC nursing home chains in exchange for the right to continue providing pharmacy services to the nursing homes. 
In 2010, Omnicare settled Resnick's False Claims Act suit that had been taken up by the U.S. Department of Justice by paying $19.8 million to the federal government, while Mariner and SavaSeniorCare settled for $14 million.
A second whistleblower lawsuit filed against Omnicare it by Resnick and Total Pharmacy Services V.P. Maureen Nehls related to kickbacks that were part of its 2004 acquisition of Total Pharmacy Services was settled for $17.2 million by Omnicare and $5 million by the Total Pharmacy owners.
