Vigilance needed
Commenting on the findings for this news organization, Jerrold F. Rosenbaum, MD, Stanley Cobb Professor of Psychiatry, Harvard Medical School, Boston, urged caution when combining benzodiazepines with opioids.
“There are situations where you need to be circumspect about the use of benzodiazepines, and that’s clearly when people are being prescribed them in combination with other drugs that could be either sedating or respiratory depressant,” said Dr. Rosenbaum, who was not involved with the research.
“This paper reminds us that physicians need to be particularly vigilant about situations where patients might be combining the two agents,” he added.
Dr. Rosenbaum noted that patients who are using more medication than prescribed are at risk “for not appreciating the synergy” between the two treatments in terms of adverse events such as respiratory depression.
In addition, “if they’re intending to do themselves harm, the lethality of an overdose will be certainly far more than the benzodiazepines or opiates alone,” he said.
Another potential challenge for clinicians are situations in which patients are taking benzodiazepines for preexisting conditions that also require opiates. “Then you have to use special vigilance and try to use lowest doses to reduce the total burden of medication to minimize the potential risk,” said Dr. Rosenbaum.
The study was funded by the National Institutes of Health. Dr. Xu has reported no relevant financial relationships.
