Iowa Attorney General Tom Miller joined four other states today in suing Purdue Pharma and its former president and board chairman, Richard Sackler, alleging that the drug company engaged in unfair, deceptive and unlawful practices in the marketing of OxyContin, helping fuel the nation’s opioid crisis. Iowa’s lawsuit, filed in Polk County District Court, seeks restitution and civil penalties under Iowa’s Consumer Fraud Act. It alleges that Purdue, and its related companies Purdue Frederick Co., Purdue Pharmaceuticals and P.F. Laboratories, repeatedly made false and deceptive claims that OxyContin was safe and suitable for a wide range of pain patients. Kansas, Maryland, West Virginia and Wisconsin also filed separate suits against Purdue on Wednesday, joining 39 other states that have sued the company.
