We thank Dr. Sanders for highlighting the need for clinical equipoise in considering the risks and benefits of medications—something that is true for benzodiazepines, antipsychotics, antidepressants, and in fact all medications. He reminds us that the risks of misuse, dependence, and withdrawal associated with benzodiazepines led to a boxed warning in September 2020 and highlights recent trends of fatal and nonfatal benzodiazepine overdose, especially when combined with opiates.
Our article, which aimed to educate clinicians on benzodiazepine pharmacology and patient-specific factors influencing benzodiazepine selection and dosing, did not focus significantly on the risks associated with benzodiazepines. We do encourage careful and individualized benzodiazepine prescribing. However, we wish to remind our colleagues that benzodiazepines, while associated with risks, continue to have utility in acute and periprocedural settings, and remain an important treatment option for patients with panic disorder, generalized anxiety disorder (especially while waiting for other medications to take effect), catatonia, seizure disorders, and alcohol withdrawal.
We agree that patient-specific risk assessment is essential, as some patients benefit from benzodiazepines despite the risks. However, we also acknowledge that some individuals are at higher risk for adverse outcomes, including those with concurrent opiate use or who are prescribed other sedative-hypnotics; older adults and those with neurocognitive disorders; and patients susceptible to respiratory depression due to other medical reasons (eg, myasthenia gravis, sleep apnea, and chronic obstructive pulmonary disease). Further, we agree that benzodiazepine use during pregnancy is generally not advised due to the risks of neonatal hypotonia and neonatal withdrawal syndrome1 as well as a possible risk of cleft palate that has been reported in some studies.2 Finally, paradoxical reactions may be more common at the extremes of age and in patients with intellectual disability or personality disorders.3,4
Patient characteristics that have been associated with a higher risk of benzodiazepine use disorder include lower education/income, unemployment, having another substance use disorder, and severe psychopathology.5 In some studies, using benzodiazepines for prolonged periods at high doses as well as using those with a rapid onset of action was associated with an increased risk of benzodiazepine use disorder.5-7
Ultimately, we concur with Dr. Sanders on the perils of the “irresponsible use” of medication and emphasize the need for discernment when choosing treatments to avoid rashly discarding an effective remedy while attempting to mitigate all conceivable risks.
