Research Funded By The Commonwealth Fund Shows Overdose Risk Quintuples With Opioid and Benzodiazepine Use
In the first 90 days of concurrent opioid and benzodiazepine use, the risk of opioid-related overdose increases five-fold compared to opioid-only use among Medicare recipients, according to a new study from the University of Pittsburgh School of Pharmacy, published today in JAMA Network Open.
The U.S. Centers for Disease Control and Prevention recommends against concurrent use of opioids and benzodiazepines, but nearly a quarter of Medicare recipients who are prescribed opioids also fill prescriptions for benzodiazepines. Both drugs have sedative effects.
"Patients who must be prescribed both an opioid and a benzodiazepine should be closely monitored by health care professionals due to an increased risk for overdose, particularly in the early days of this medication regimen," said Inmaculada Hernandez, Pharm.D., Ph.D., assistant professor at Pitt's School of Pharmacy and the study's lead author. "Moving forward, policy interventions should focus on preventing concurrent exposure instead of simply reducing the length of time patients use both drugs."
Hernandez and her team used 2013-2014 Medicare Part D data to assess how the duration of simultaneous exposure to the two types of drugs impacts the risk of overdose. Beneficiaries not being treated for cancer who filled at least one opioid prescription during that year were included in the analysis, which ultimately looked at more than 71,000 beneficiaries who averaged 66.5 years of age...
