Amidst the opioid epidemic, there has been an increasing focus on opioid utilization in U.S. emergency departments (EDs). Compared with other opioids, little is known about the use of tramadol over the past decade. Tramadol has uncertain efficacy and a concerning adverse effect profile compared with traditional opioids. ⋯ Although the use of traditional opioids decreased from 2007 to 2018, the use of tramadol increased. Increases were largest among older patients, who may be more susceptible to the adverse effects associated with this medication. Further research in the appropriate use of tramadol in the ED setting is warranted.
