Health and safety agencies in Iowa have issued an advisory to warn Iowans of counterfeit pain pills containing dangerous synthetic opioids. The Iowa Division of Criminal Investigation’s (DCI) laboratory analyzed pills made to resemble the prescription pain reliever oxycodone, finding them to contain more powerful and illicit synthetic opioids fentanyl and U-47700, putting users at higher risk of opioid overdose. Iowans with questions about synthetic opioids and emergency opioid reversal procedures can contact the Iowa Poison Control Center at 800-222-1222 or http://www.iowapoison.org.
