Benzodiazepines have been commonly prescribed for the treatment of anxiety and insomnia in the last few decades. There has been a rising concern regarding safety of benzodiazepines due to overdose related deaths, addictions, and cognitive side effects. COVID- 19 pandemic is expected to cause a mental health crisis. Several studies have shown an increase in anxiety and insomnia. This could mean that prescriptions of benzodiazepine could increase due to increase in anxiety and insomnia. We caution health care providers to use best practices and treat patients with psychotherapy as the first line of treatment and not pharmacotherapy. Prescription Drug Monitoring programs (PDMPs) were started due to this concern of overdose deaths, diversion related to opioids and benzodiazepines. PDMPs are mandatory in most states in the United States of America now.We recommend all health care providers to look at their benzodiazepine prescribing practice, monitor PDMP data and make policies to implement changes in order to avoid the next crisis of benzodiazepines after opioids.


Benzodiazepines have been around since the 1960s and they have been one of the most commonly prescribed medications worldwide. Over years, there has been a rising concern of the risk of overdose-related deaths, addiction, and long-term cognitive concerns with benzodiazepines. As per the Centers for Disease Control and Prevention (CDC), there were 67,367 deaths in the United States due to overdose in 20181. Synthetic opioids were the main drugs involved in deaths. As per the National Institute on Drug Abuse (NIDA), benzodiazepines were involved in more than 30 percent of the opioid-related overdose-related deaths2. Due to these rising concerns, Food and Drug Administration (FDA) and CDC mandated changes. In 2016, the CDC came up with guidelines and recommended avoiding combined use when possible. Prescription drug monitoring program (PDMP) is an electronic way to monitor the dispensing of controlled substances used in most states in the United States of America (USA). Due to the concern of diversion of opioids, PDMPs started to flourish in 2002 and they are now mandated in most states in the USA. There have been several studies done on PDMP. Some studies have shown a decrease in the number of opioid and benzodiazepine prescriptions3. Others like the study done by Di Liang on Medicaid enrolled from 2010- 2017 did not find any change in benzodiazepine prescribing practice with mandating the use of PDMP4.

There has been a staggering increase in the number of benzodiazepine prescriptions in the last couple of decades in the USA. According to a serial cross-sectional study (January 1, 2003, through December 31, 2015) done by S. Agarwal benzodiazepine prescriptions in outpatient settings increased substantially from 3.8% to 7.4% of visits5. Psychiatrists prescribing benzodiazepines have been stable (29.6% vs 30.2%) but primary care physicians have increased (3.6% vs 7.5%)5. Primary care accounted for about half of all benzodiazepine prescriptions. This pattern of the rise of benzodiazepine prescriptions is very concerning amid the opioid epidemic and the COVID-19 pandemic.

As per NIDA, opioid-related overdose deaths increased from 3,442 in 1999 to 17,029 in 2017 but the number of deaths dropped to 14,975 from 2017-2018 in the USA. Deaths due to benzodiazepine overdose increased from 1,135 in 1999 to 11,537 in 2017 but it declined to 10,724 from 2017 and 2018 in the USA 2. As per the New York Times, this decrease was probably due to tightening of the opioid prescriptions6.

The COVID-19 pandemic could cause a mental health crisis. Studies have shown an increase in anxiety and insomnia in health care providers as well as in the general population7-9. Per a survey done by the American Psychiatric Association in March 2020, 48 percent of the general population reported anxiety, 36 percent informed that pandemic has seriously affected their mental health and 19 percent reported insomnia 7. A systematic review and meta-analysis done by S.Pappa during this time of pandemic showed a prevalence of 23.2 percent anxiety and 22.8 percent depression in health care workers8. In one of the studies done in China on health care providers who treated COVID patients, 50.4 percent reported depression, 44.6 percent anxiety, 34 percent insomnia, 71.5 percent distress9. This rise in anxiety, insomnia, and depression is alarming in both the general population and health care workers. Hence, it can be anticipated that there will be an increase in use of benzodiazepine prescriptions.

Per the National Institue of Mental Health (NIMH), suicide was the second leading cause of death among individuals between the ages of 10 and 34, and the fourth leading cause of death among individuals between the ages of 35 and 5410. During the 20 years from 1999 through 2018, the total suicide rate increased 35% from 10.5 to 14.2 per 100,000 10. Poverty, unemployment, opioid use, are all risk factors for suicides. There has been an upswing in unemployment due to the COVID-19 pandemic, so there could be an increase in suicides as well. Overdosing is one of the common methods of the suicide attempt. Amid this pandemic, we need to be very careful about what we are prescribing to avoid intentional and accidental overdose. Social isolation and lack of ready access to support is another risk factor11. Social isolation measures taken due to pandemic could have a ripple effect on mental health as the support network could be disrupted for some people. There is a lot of apprehension about getting sick, dying, finances, housing, unemployment, childcare due to pandemic. The longer this pandemic continues the worse it is going to be for mental health. Stress can activate the hypothalamic-pituitary axis which indeed increases cortisol. Cortisol is a steroid hormone that plays a role in stress response and immunity along with other functions. Chronic stress could increase inflammatory conditions in the body, decrease immunity12. During this time of pandemic when we don’t have any treatment for COVID-19, we need our immunity to be good to fight this infection.

Insomnia can be triggered by acute stress and over time it can become chronic. People who have high sleep reactivity are more prone to insomnia with stress. Sleep reactivity is a trait that some individuals can have, it is also linked to the risk of depression and anxiety13. There has been an increase in insomnia due to the pandemic and it could be explained due to the cognitive distortions, ruminations that some people can have at bedtime. Ruminations in bed can increase anxiety and relate bedtime with anxiety, therefore relaxation techniques like progressive muscle relaxation can help us relax at bedtime and decrease sleep latency. A study done by Palagini on subjects with insomnia showed low resilience was related to high stress-related sleep reactivity, emotional dysregulation, and hyperarousal14.

American College of Physicians released guidelines for the management of insomnia in 2016. According to those guidelines, Cognitive Behavioral Therapy for insomnia (CBT- I) is the recommended first treatment modality. If CBT-I alone is ineffective then short-term use of sedating medications is recommended after discussing the risk, benefits, and making shared decisions15. CBT-I includes various techniques like sleep hygiene to regulate the circadian rhythm, matching sleep opportunity with sleep efficiency, restoring homeostatic regulation of sleep by sleep restriction, relaxation techniques, and stimulus control. A systematic review done to compare medications with CBT-I showed CBT-I to be more effective in the long term due to more durable benefits and fewer side effects16.

Benzodiazepine use has been associated with cognitive side effects, so there have been concerns about the risk of dementia with long term use. Benzodiazepines act as GABA-A receptor agonists, they allosterically modulate GABA-A receptors. The inhibitory GABA-A could modulate the cognition and cause negative cognitive effects. These receptors are located not just in the limbic system but in the cerebellum, spinal cord, cerebral cortex as well. There have been several studies and meta-analyses done over the past 2 decades. A meta-analysis was done by Barker, Greenwood, and Jackson (2004, 2005) that showed long-term cognitive side effects17. S. Crowe did a meta-analysis and published in 2017, the meta-analysis revealed statistically significant, negative effects for the cognitive domains of working memory, processing speed, divided attention, visuoconstruction, recent memory, and expressive language18. Billioti de Gage and colleagues did a study in Canada on the link between benzodiazepines and Alzheimer's dementia and they found out a two-fold increase in risk with more than 180 days of use. They also found out that long-acting benzodiazepines increased the risk of more than shorter-acting benzodiazepines19. A nationwide large cohort and case-control study done on Danish patients published in 2020 did not reveal an association between benzodiazepine and z-drugs and subsequent dementia20.

There is a lot of debate on the use of benzodiazepines in the medical community. Some support the use due to immediate benefits and some don’t due to addiction, tolerance, withdrawal, risk of cognitive decline, falls, etc. Conflicting studies makes it even harder to make the right decision at the time when patients are seen in the clinics. There are limited resources for psychotherapy and that makes it even harder for our primary care colleagues to treat anxiety and insomnia. Overall there is no denying the fact that we are seeing more overdose-related deaths, addiction problems, suicides2,10,21. Due to the COVID-19 pandemic, mental health crisis is expected and we are probably going to see even more rise in anxiety and insomnia. Benzodiazepines could be alluring during this time due to their “quick fix” nature, but we know due to this “quick fix”, patients are not able to develop coping skills to cope with the stressors22-26. Patients get dependent on medicines and that’s how the long-term use becomes an addiction problem. The first line of treatment for anxiety and insomnia is psychotherapy, so that should be used before moving on to pharmacotherapy. There are several types of psychotherapies available like Cognitive Behavioral Therapy (CBT) for anxiety, CBT for insomnia, supportive therapy, interpersonal therapy, trauma-focused therapy, etc. CBT can help develop rational thinking and help patients cope with their ruminations and worrying which indeed could help with anxiety and insomnia. Building a positive attitude by psychotherapy can last long and help us develop resilience to cope with any stressors in life. Resilience is a trait that shows how adaptable an individual is to stressful events. People with high resilience can adapt and are at low risk for anxiety, insomnia with stress. Whereas people with low resilience are at high risk for insomnia and anxiety during stressful events like the current pandemic. Low resilience could be the reason for the increase in the rates of anxiety and insomnia in some people with the current pandemic. Resilience could be internal or external. Internal resilience is inborn but external resilience could be achieved with the help of psychotherapy. Teaching this trait to people can help develop better-coping skills which could decrease the rates of anxiety and insomnia.

Current NIDA and CDC data of decrease in overdose deaths related to benzodiazepines and prescription opioids are reassuring. This shows that we can protect our community through careful prescribing practices. We recommend all health care providers to look at their benzodiazepine prescribing practice, monitor PDMP data, and make policies to implement changes to avoid the next crisis of benzodiazepines after opioids during this COVID-19 outbreak and thereafter.
