In 2012, under prosecution by the United States Department of Justice (DoJ) based on combined investigations of the Department of Health and Human Services (HHS-OIG), FDA and FBI, primarily concerning sales and marketing of the drugs Avandia, Paxil and Wellbutrin, GSK pleaded guilty to promotion of drugs for unapproved uses, failure to report safety data and kickbacks to physicians in the United States and agreed to pay a US$3 billion (£1.9bn) settlement. It was the largest health-care fraud case to date in the US and the largest settlement by a drug company.
