How can you check or investigate the possibility that your patient is diverting his/her prescribed medication? This is clearly not easy, as behaviors that you see are concerning to you, could well be a sign of an illegal activity. It is important to follow patient patterns and behaviors and keep your ears open for red flags. A critical element is in record keeping and monitoring patterns. One way we do this in my practice is to have a very good relationship with those individuals who are investigating drug diversion. -- Response provided by John F. Peppin, DO, FACP
