The Prevalence of Prescriptions and
Their Indications
B
enzodiazepines are reportedly the most frequently pre-
scribed psychotropic medication. Among adults in the
United States and Canada, 3% to 4% are using BDZs at any
one time' About 100 million prescriptions are written per
year. The European Study of the Epidemiology of Mental Dis-
orders (commonly referred to as ESEMeD) investigated the
use of ADs and BDZs in 2 425 respon dents from 6 countries.
In the nonhelp-seeking population, BDZs were used more
commonly than ADs, while in the help-seeking population,
with a 12-month prevalence of major depressive disorder or
anxiety disorder, BDZs were used as commonly as ADs.^ In
an Australian study,'' 16% of the adults aged 65 years and
older
n
= 3970) had at least BDZ prescription and the pre-
scription prevalence increased with age.

BD Zs' sedative, hypnotic, and anxiolytic properties are used
for various psychiatric and medical conditions including
anxiety disorders, sleep disorders, seizure disorders, move-
ment disorders, and muscle spasticity. They are used in
anaesthesiology and for the symptomatic treatment of agita-
tion associated with other psychiatric and neurological disor-
ders including psychotic, mood, and cognitive disorders.'' In
emergencies they are the preferred treatment of withdrawal
from alcohol and sedative-hypn otics as well as agitation from
stimulants.
Tolerance to sedative effects usually develops am ong p eople
receiving maintenance therapy with a stable dose of BDZs;
by contrast, the memory-impairing effects can persist after
several years of daily administration,̂ Overdoses are almost
never fatal unless occurring in combination with other seda-
tive agents such as alcohol or opiates.
The reinforcing effects of BDZs may not only be mediated
through bind ing of the alpha 1 or lambda 2 subtypes of
GABA receptors but also via an opioid m echanism, A partial
mu receptor antagonist such as naltrexone m ay reduce anxio-
lytic and positive subjective effects of BDZs. This may
explain the high level of co-occurrence of BDZs and opioid
dependence. Of interest, BDZs are the only major class of
drugs with abuse liability that decrease dopamine levels in
the m esolim bic system,
From Physiologic Dependence to Loss of ontrol
The dose and duration of exposure to BDZs determines the
developm ent of physiological depen dence. It is almost never
seen in patients treated for less than 2 weeks but occurs in
about 50% of patients treated daily for more than 4 months.
Short- and long-acting BD Zs produce comparable severity of
withdrawal. The development of physiological dependence
is reduced with intermittent, eompared with continuous,
exposure to BDZs,
Among people exposed to BDZs, a small subset, likely
among those who have abused o ther substances, will develop
compulsive drug-seeking behaviour with loss of control and

positive family history of drug or alcohol dependence, given
that some of the risk may be hereditary.^ Most patients treated
chronically with BDZs, who presumably may have physio-
logical dependence, do not develop compulsive substance
use,^ and some patients present with compulsive substance
use without physiological depen dence. The abuse potential of
BDZs depends not only on the drug receptor selectivity but
also on the characteristics of the individual and environmen tal
circumstances.
BDZs as a primary substance of
buse
in people adm itted for
addiction treatment make up less than 1% of all admissions.
Most of these people report abuse of alcohol or opioids in
addition to BDZs.^ The presence of another co-occu rring psy-
chiatric disorder (mood, anxiety, and Cluster C personality)
occurs in up to 50% of these admissions. Among patients on
methadone maintenance treatment, 40% to 5 0% abuse BD Zs.
These rates are not significantly reduced by methado ne m ain-
tenance alone.
Guidelines for Respon sible Prescription
APA and NICE. The A PA guideline for the treatment of panic
disorder' and the NICE guideline on the management of
panic disorder and GAD recommend SSRIs and not BDZs as
the best choice of medication, alongside CBT and self-help
based on CBT principles. BDZs are associated with a less
good outcome in the long term and should not be prescribed
beyond 2 to 4 weeks in GAD and are not recommended for
panic disorder.
BDZs Compared ith non-BD Z Antianxiety Medication and
CBT.
Non-BDZ antianxiety medication and CBT often take
week s before there is any beneficial effect, thus the sh ort-term
prescription of high-potency BDZs may remain an option
when patients exp ress an urgent need for the reduction of high
levels of anticipatory anx iety and the reduction in the severity
of panic attacks. BDZs with slower onset and longer action
may be safer than fast-acting agents.
BDZs Compared With SSRIs and SNRIs.
In the case of
comorbid anxiety and depression, SSRIs and (or) SNRIs are
the first-line medication but BDZ s may also provide benefits
both for speed of response and for overall response. ADs
should also be started early as the shorter the time elapsed
between the onset of GAD and first adequate p harmacolog ical
treatment the better the progn osis.'^
Coneerns Associated ith the Prescription of BDZs.
Concerns include:
1.
BDZs mainly have a favourable side effect profile;
howev er, patients, the elderly in particular, may
experience sedation, fatigue, slurred speech, memory
impairment, and weakness.
2. Even when the SSRI and (or) CBT has started to work,
it. Provided with short-term symptomatic relief the
patient may also lose motivation to follow all the CB
steps.
3.
Even after a few weeks of BDZ treatment, some
patients will experience withdrawal reactions on
discontinuation similar to an anxiety relapse, resultin
in their reluctance to discontinue the BDZ.
Identifying and Targeting High Risk People.
This includes:
1. Screening for sedative-hypnotic use through a
nonthreatening personal and family history and
possibly urine toxicology.
2. Regular monitoring for signs of abuse or dependence
as well as concurrent abuse of alcohol or other drugs
3.
Individual reassessment of risks and benefits of
prescription at regular intervals.
4. Reduction of physiological dependence, through:
• Use of adequate doses over a few w eeks only.
• Drug holiday s; that is, intermittent use of medicatio
only in the case of high-anxiety situations, for
example, in a GAD .
5. Differentiation of common physiological dependence
compared with rarer iatrogenic addiction.

Strategies for patients with comorbid anx iety or mood diso
ders and sedative-hypnotic use disorders will include:
1. Very gradual taper of medication during several
months. Referring the patient to a website such as the
Ashton manual'^ may be of help.
2. Conversion to, and stabilization on, equivalent dose
alternative BDZ with a slower onset and a longer
duration of effect; that is, conversion from alprazolam
to clonazepam.
3.
Discontinuation of BDZ and stabilization on an
alternate GABAergic agent with a higher safety
profile; that is, carbamazepine or valproate.
4. Implementation of CBT, typically for several weeks
months, helps the patient to recognize and manage
symptoms of withdrawal and rebound anxiety, while
helping the transition in developing symptom contro
and self-efficacy.
5. In the case of recurrence of mood or anxiety problem
that may or may not mimic withdrawal sym ptoms,

BDZs Should Be Considered in the
Long-Term Treatment of Mood and
Anxiety Disorders
B
enzodiazepines are one of the oldest classes of
pharmaco- therapeutic medications.' Discovered in
1955 by Stem bach, they have been widely used in many areas
of medicine. Most experts and regulatory guidelines recom-
mend the short-term use of BDZs in the treatment of tnood
and anxiety disorders.^ However, the long-term u se of BDZs
in treating mood and anxiety disorders has been controver-
sial. Some have argued that the long-term use of BDZs will
be associated with increased risk for tolerance, dose escala-
tion, and dependence.' We argue here that the benefits of
long-term BD Z use outweigh the potential adverse effects for
most patients.
We suggest that there are 4 specific reasons to consider the
use of BDZs as part of the overall treatment of mood and anx-
iety disorders. First, they work BDZ s rapidly, reliably, and
robustly relieve anxiety symptoms and improve sleep. As
there is clear evidence that mood and anxiety disorders are
chronic, long-term conditions, there is often a relapse of
symptoms when there is a reduction in dose or discontinua-
tion of
BDZs.
This is sometimes interpreted as evidenee that
dependence has occurred (which may be the case) but the
most parsimonious explanation is that the condition has not
spontaneously remitted and further treatment is indicated.

owing to tolerance, has been exaggerated. The little available
evidence in this area suggests that a very small minority of
patients have dose escalation (which could be due to toler-
ance). We w ill suggest some methods to minimize the risk of
dose escalation. Third, BDZs are often better tolerated than
SSRIs, atypical antipsychotics, or other classes of medica-
tions employed to treat anxiety that h ve side effects of weig ht
gain and sexual dysfunction. Fourth, absence of recent evi-
dence on the clinical usefulness of BDZs does not equal
inef
fectiveness. As there have been no new BD Zs available on the
market in the last 2 decades, there has been little financial
motivation among pharmaceutical companies to conduct
large-scale RCT s of BDZ s in the treatment of m ood and anxi-
ety disorders. In summary, we suggest that clinicians need to
carefully consider the use of BDZs in the long-term m anage-
ment of mood and anxiety symptoms, and researchers need to
conduct large-scale RCTs in this area.
BDZs Are Efficacious
BDZs reduce anxiety symptoms am ong patients with primary
anxiety disorders, and anxiety symptom s among patients with
a mood disorder. The strongest evidence for the effectiveness
of BDZs has been among patients with social phobia, GAD,
and panic disorder.^ RCT s have dem onstrated that BDZs are
effective in treating each of these anxiety disorders . There has
been a dearth of studies that have examined the use of BD Zs
among patients with OCD and PTSD.^ Although the few
studies examining the use of BDZ s among patients with OC D
and PTSD have not found strong evidence for their
use.
North
American psychiatrists commonly use BDZs in the treatment
of these
In patients with mood disorders, anxiety symptoms often are
substantial and associated with poor outcomes (for exam ple,
increased suicidality^ and functional im pairm ent). Some stud-
ies have shown that addition of regularly dosed (that is, not
pm) clonazepam to ADs can accelerate the response among
depressed patients, compared with those who receive ADs
alone.' The treatment of anxiety symptoms among patients
with bipolar disorder is especially important. However, as
SSRIs may heighten the risk of mania and rapid cycling, we
suggest that BDZs may be especially beneficial for these
patients. There is a need for further study in this area.
h Dangers of Tolerance and Dependence on BDZ s
Have Been Catastrophized
Is a diabetic patient addicted to insulin? What about asthmat-
ics;
are they addicted to salbutamol? In our opinion, the dan-
gers of developing tolerance and dependence on BDZs have
been exaggerated. Long-term follow-up studies have shown
that the incidence of dose escalation (a possible indicator of
tolerance) occurs in only a small minority of patients. In a
large population-based study' that followed over 2000
patients treated with BDZs for more than 2 years, the inci-
dence of
dose
escalation was small (1.6%). Physical depend-

To m inimize the small risk of dose escalation, we sugg est

likely to be enormously helpful. Second, minim ize the us

Industry s Influence on BDZ Use?

recommended only for short-term use by clinical practice
guidelines.
An example of this issue is specifically in the treatment of
GAD. Bemey et al'° reviewed the literature and found that
there were 22 RCTs com paring ADs to BD Zs. None of them
showed superiority of ADs over BDZs in the treatment of
GAD . They concluded that there has been a shift in prescrib-
ing ADs instead of BDZs for GAD without any evidence to
support this shift.
In summary, judicious long-term use of BDZs should be
thoughtfully considered in treating patients with mood and
anxiety disorders. We also suggest that there is a need for
long-term studies comparing the safety and efficacy of BDZ s
to newer ADs and antipsychotics.

ebutt ls
Should the Prescription of BDZs Be
Based on an Act of Faith?
My esteemed colleagues and I agree that BDZs are a useful
group of medications, and we do not seem to differ as to their
short-term use. Dr Sareen and Dr Stein advocate for the
long-term use of BDZs in treating mood and anxiety disor-
ders, and, in support of their argument, they note that a reduc-
tion in the dose of BDZs may lead to symptomatic relapse, a
small sample subset will develop dose escalation (tolerance or
dependence?), and that BDZs are often better tolerated than
SSRls. So far, so good
absence of recent evidence on the clinical usefulness
of BDZs does not equal ineffectiveness . . .
clinicians need to carefully consider the use of BDZs
in the long-term management of mood and anxiety
symptoms and researchers need to eonduct
large-scale RCTs.
Is the latter to be considered before the studies?
In the case of panic disorder, where standard professional
guidelines consistently recommend the prescription of SSR ls
over BDZs, Roy-Byrne et al' state that BDZs work rapidly
but are restricted by their narrow range of efficacy across dis-
orders, the risk of physiological dep endence and w ithdrawal,
and the risk of abuse. While the co-prescription of BDZs to
anxious patients treated with ADs is common, "no placebo-
controlled studies have yet been done ... [on] the effective-
ness of augmenting SSRls with ben zod iazepin es."'' '
'°^^
Th e
same could be said about the treatment of comorbid anxiety
and depression. Therefore, in summary, while there is evi-
dence to support initial select co-prescription of BDZs with
SSRls, the wide open questions remain: For how long? And
at what cost?
My second surprise is that in an argument about long-term
treatment and, presumably, treatment resistance, the role of
psychotherapy, and CBT in particular, is not mentioned.
Surely, the long-term treatment of mood and anxiety disor-
ders is not solely adequate pharmacology. Is not combined
psychotherapeu tic connection w ith the patient as important?
Lastly, as an addiction specialist, I am taken aback with the
suggestion that anxiety could be a "BDZ-deficiency syn-
drome" similar
to
"diabetes and its insulin deficiency." W hile
the incidence of dose escalation is relatively small in samp les
at low risk for addiction, this in no way negates the higher
biopsychosocial risks of BDZ dependence and other sub-
stance misuses in anxious and (or) depressed patients, as evi-
denced by the recent large-scale epidemiologic studies of
comorbidities. The vicious cycle between the misuse of
drugs, including BDZs, and the occurrence of anxiety and
(or) mood disorders is a common clinical presentation.
In summary, at issue is the risk-benefit analysis of the
long-term prescription of BDZ s in mood or anxiety disorders
in the absence of adeq uate research.
fully support the search
for newer medication with improved safety profiles. A care-
ful risk analysis before the prescription of BD Zs is required.
CBT, as a widely studied and validated psychotherapeutic
treatment, should also be considered as a first-line augmenta-
tion strategy or alternative to limited pharmacological
response. The complexity of the withdrawal syndrome
resulting from BDZ dependence precludes me to advocate
their long-term prescription in the absence of adequate

Emerging Evidence That Risk of
Fractures Is Not Only Associated
With BDZs But Also Other
Psychotropic Medications in the
Elderly
W
e thank Dr el-Guebaly for his thoughtful com ments on
the risks of BDZ use and his recommendations for
methods to reduce these risks. We agree with many of his
comments.
Specifically, we agree with Dr el-Guebaly that the risk of dose
escalation and tolerance with BDZ s is low. Noneth eless, phy-
sicians should prescribe these m edications judiciou sly and in
a responsible mann er. There is also a need for further rese arch
to guide clinicians in understanding wh ich patients are specif
ically at risk of dose escalation and abuse of BDZs,
Anecdotally, we often have patients who are struggling with
severe anxiety and report worry about becoming addicted to
medications. In our experience, these patients are at low risk
of abusing BDZ s, Conversely, patients with anxiety disorders
who have comorbid Cluster B personality traits, impulsivity,
aggression, or somatization problems often do not do well
with BDZs, in our experiences. In such patients, we prefer
AD s and, if necessary, small doses of antipsyehotics for man-
agement of anxiety symptoms.
We disagree with 2 specific points made by Dr el-Guebaly,
First, Dr el-Guebaly mentions one of the common concerns
about BD Zs' is that they are associated with increased risk of
falls in the elderly. W e point to recent emerging data that show
an association between SSRIs and risk for fractures. Also, a
recent metaanalysis^ examining the impact of 9 medication
classes on falls in the elderly also shows that the increased risk
for falls is not only associated with BDZs but also ADs and
neuroleptics. Interestingly, in 1989 the state of New York
changed po licies such that BDZs would require triplicate pre-
scriptions. This policy had a substantial impact on reducing
the prescription of BD Zs in New Y ork, How ever, this reduc-
tion in prescriptions did not have an impact on the prevalence
of hip f rac tures , - ' Al though the la t te r s tudy^ used
quasiexperimental data, and causal inferences cannot be
inferred, these findings are interesting and sugg est that BD
may not b e a strong contributor to falls in the elderly.
Second, Dr el-Guebaly com ments that the APA gu idelines
panic disorder, first edition, do not recommend the use
BDZ s for the treatment of panic disorder. Please note that
updated guidelines published by the APA in 2009 * reco
mend the use of BDZs in certain patients with panic disord
These guidelines suggest that monotherapy with BDZs
panic disorder can be used when com orbid depression is no
major issue.
In summary, we believe that BD Zs, when prescribed with
awareness of their risks and benefits, have an important r
to play in the treatment of patients with mood and anxi
disorders.
