The Illinois Department of Financial and Professional Regulation suspended both the physician and surgeon license of Gerald Saul Kane, M.D., of Chicago suburb Highland Park. Three patients treated by Dr. Kane received a surplus of multiple prescriptions in a short period of time. This included more than 20,000 doses of OxyContin and other pain killers and controlled substances. Two patients died of drug overdoses shortly after receiving their last prescriptions from Dr. Kane. The department alleges that the doctor did not appropriately treat these patients by failing to prescribe medically appropriate amounts of controlled substances and failed to monitor the patients for signs of dependence on these drugs, leading to the wrongful death of the two patients. The department issued his summary claiming that allowing Dr. Kane to continue to practice medicine after this medical malpractice would put the safety of the public in danger. His license has been suspended and his license to prescribe controlled substances has been revoked.
