Oct. 30, 2017 (HealthDay News) -- Opioid addicts saved by the overdose reversal medication naloxone are still in danger following their close brush with death, a new study shows.About 10 percent of overdose patients saved with naloxone (Narcan) in Massachusetts hospitals ended up dying within a year, Harvard researchers reported.Further, half of those who died did so within one month of their rescue, the investigators found."The opioid overdose patient who sobers in the hallway, is offered a detox list, and then is discharged has a one-in-10 chance of being dead within one year, and their highest risk is within the first month," said lead researcher Dr. Scott Weiner. He is director of the Comprehensive Opioid Response and Education Program at Brigham and Women's Hospital in Boston.Patients saved with naloxone are very likely to suffer withdrawal cravings that could drive them to overdose within a matter of weeks, Weiner said."Naloxone is not the panacea solution to the crisis," Weiner said. "Patients who survive opiate overdose need to be considered extremely high risk and should receive interventions like offering buprenorphine or offering counseling and referral for treatment prior to discharge from the emergency department."
