However, it can be sedating and may augment central nervous system (CNS) depression in patients also receiving opioids (3). Because recent evidence shows that concomitant opioid and gabapentin use is associated with opioid-related mortality (4), understanding whether similar risks exist when pregabalin is coprescribed with opioids is essential.Objective: To examine the risk for opioid-related death among persons coprescribed pregabalin and opioids.Methods and Findings: We conducted a population-based, nested case–control study of Ontario residents eligible for public drug coverage who received ...References1.
