The Case for Caution When Prescribing Benzodiazepines

Are benzodiazepine prescriptions contributing to the opioid overdose epidemic?

CLINICAL REFLECTIONS

While the deadly opioid epidemic has progressed during the past 2 decades, more and more patients have left their doctors’ offices with prescriptions for benzodiazepine medications (BZDs). Across the medical profession, the percentage of outpatient visits resulting in a BZD prescription has increased from 3.8% in 2003 to 7.4% in 2015.1 It is estimated that concurrent use of BZDs and opioids may occur in as many as 50% of opioid overdose deaths.2 This shocking statistic suggests the possibility that more cautious and conservative use of BZDs by all who prescribe them has the potential to save thousands of lives per year. 

Evidence of Misuse

During the time period studied by Agarwal et al,1 outpatient psychiatrists manifested a stable pattern of BZD prescribing, delivering BZD prescriptions to the patient in 30% of psychiatric visits. Overall, BZD prescriptions written by psychiatrists account for approximately one-sixth of the more than 25 million prescriptions that are written each year.3 In the years 2015 and 2016, 30.6 million US adults reported BZD use in the past year; of these, 5.3 million were deemed to be misusing BZDs.3 The most common type of BZD misuse occurs when prescribed BZDs are diverted and utilized by individuals who are not receiving them for a legitimate medical indication. 

These threads of data suggest that some BZDs prescribed by psychiatrists end up being misused by individuals who are also misusing opioids, and that some of these opioid overdose deaths are potentiated by BZDs prescribed by a trusting psychiatrist. Are these BZDs that originate in mental health settings a factor in hundreds of yearly opioid overdose deaths, or in thousands? Although the magnitude of this problem is not known, it is likely that psychiatrists who exercise more caution in prescribing BZDs can play a role in doing less inadvertent harm.

Nearly a decade ago, Jones et al4 performed a comprehensive review of studies on the combined use of opioids and BZDs. They concluded that “that the co-abuse of opioids and BZDs is ubiquitous around the world,” that BZDs are utilized by many opioid abusers to potentiate opioid intoxication, and, that the co-abuse of opioid and BZDs “has negative consequences for general health, overdose lethality, and treatment outcome.”

Perhaps their 2012 conclusion that physicians should exercise more caution and vigilance in prescribing BZDs is reflected in the fact that psychiatrists have paid attention, and not increased our rate of BZD prescribing. Whereas psychiatric BZD prescriptive practices have remained stable, other physicians, especially primary care providers, are delivering nearly twice as many BZD prescriptions to patients.1 However, in view of the subsequent progression of the opioid crisis and the mounting overdose death toll, reducing the rate of BZD prescriptions in psychiatric practice may indeed be a worthwhile, life-saving consideration.

Gourlay et al5 suggest that by adhering to universal precautions in pain medicine, physicians are able to routinize a cautious, non-stigmatizing clinical approach that facilitates their ability to limit opioid prescriptions. It would likely be helpful for psychiatrists to adopt a parallel set of best practices and universal precautions with regards to prescribing BZDs and other psychoactive pharmaceuticals with abuse liability. Gourlay’s original 10 universal precautions can be found in the Table.5 See the Sidebar for a list of 8 universal precautions adapted from Gourlay et al5 for use by psychiatrists faced with the decision to initiate or continue pharmacotherapy with BZDs.

Discussion

Epidemiological studies suggest that individuals with untreated anxiety and mood disorders may be prone to self-medicate with nonmedical use of opioids. Use and misuse of opioid drugs may themselves aggravate symptoms of anxiety.6 It is not surprising, then, that outpatient psychiatrists sometimes provide BZD prescriptions to patients who may covertly be suffering from opioid use disorder. As substance use disorders (SUDs) have long been associated with behaviors that may be deemed antisocial,7 and one such behavior is deceptive communication,8 community-based psychiatrists in high-volume clinic settings may be at risk of being fooled by drug-seeking patients.

The ease of integrating some or all of the 8 suggested universal precautions for initiating or continuing BZD pharmacotherapy will vary from treatment setting to treatment setting. At the very least, this aspirational list of precautions may facilitate the ability of mental health professionals to offer a clinically sound integrated approach for the treatment of co-occurring psychiatric and SUDs. Integrated treatment of co-occurring disorders is the accepted standard of care for this challenging, high-risk patient population.9
