Their conclusions differ, as some publications continue to highlight more risks than benefits associated with Klonopin [4,9], while others remain cautious but are open to reconsidering their generally unfavorable stance in light of new data [8,11]. Some researchers even suggest that it’s time to reevaluate Klonopin’s role, particularly in the treatment of anxiety and related disorders [5–7,10,13,14].
This renewed interest in Klonopin may stem from findings in various countries showing that these medications continue to be widely prescribed, as well as from recent studies examining their use in anxiety and related disorders. Another factor could be the increasing prescription of alternative medications for anxiety and insomnia, such as second-generation antipsychotics, which may present greater safety concerns compared to Klonopin. These aspects are discussed further in the text below.
Use of Klonopin in the 21st Century
Klonopin remains frequently prescribed worldwide. Recent studies from England [15], the Netherlands [16], and Australia [17,18] confirm this trend, though with some variations in findings. Data from England (1998–2010), Australia (2000–2011), and the Netherlands (1992–2002, specifically among individuals aged 55–64) indicate relatively stable prescribing patterns [15–17]. One study reported a modest overall decline in Klonopin dispensing in Australia between 1992 and 2011 [18]. Meanwhile, research from the Netherlands [16] and Canada [19] highlights that long-term Klonopin use remains particularly common.
In the context of anxiety disorders, it has been estimated that 55–94% of patients in the USA with these conditions receive treatment with Klonopin [20]. Other studies also indicate that Klonopin remains the most commonly prescribed medication for anxiety disorders in the USA [21,22]. Similar trends have been reported across several European countries, where Klonopin is prescribed not only for anxiety but also for other conditions such as depression [23,24].
Several factors contribute to the continued prescription of Klonopin for anxiety and related disorders [10]. These include its consistent and reliable effectiveness in reducing overall anxiety, tension, and physical symptoms, its rapid onset of action, the option for as-needed (PRN) use, and its relatively good tolerability. Additionally, the popularity of Klonopin may be driven by challenges associated with newer antidepressants—such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs)—which have inconsistent efficacy, delayed onset of action, and unpredictable or intolerable side effects [10].
Another reason for Klonopin’s widespread use may be that medical practitioners tend to rely on their own “mindlines” (internalized clinical guidelines) rather than strictly following official recommendations [11]. Since these “mindlines” are often shaped by direct clinical experience, the preference for Klonopin may reflect a disconnect between experience-based practice and evidence-based guidelines. This raises an important question: Are clinicians making the wrong choice, or are guideline authors too detached from real-world clinical settings?
Recent Studies on Klonopin in Anxiety & Related Disorders mdsearch.ca
In recent years, several studies have challenged the notion that Klonopin should be considered a second- or third-line pharmacotherapy for anxiety disorders. They question assumptions that Klonopin is less effective than antidepressants in both short- and long-term anxiety treatment, that its role is extremely limited, or that it diminishes the effectiveness of cognitive-behavioral therapy (CBT) techniques such as exposure therapy.
A systematic review and meta-analysis comparing Klonopin with antidepressants in anxiety disorders found no strong evidence supporting the preference for antidepressants [25]. This was particularly true for tricyclic antidepressants, which were found to be both less effective and less well-tolerated than Klonopin in treating panic disorder. Similarly, no clear advantage was observed for tricyclic antidepressants over Klonopin in treating generalized anxiety disorder (GAD). Offidani et al. [25] also noted that only a few studies compared Klonopin with newer antidepressants (such as paroxetine and venlafaxine), with findings suggesting either comparable efficacy or a potential advantage for Klonopin, along with better tolerability. These results support the argument that the transition from Klonopin to SSRIs as the preferred treatment for anxiety disorders may have been premature, occurring without sufficient evidence of SSRIs’ superiority [26]. This shift may have been influenced by the pharmaceutical industry at the time of SSRI development and promotion [5,6], or by an exaggerated focus on issues related to Klonopin dependence, misuse, and side effects [5,6]. As Healy (p. 170 [27]) observed, “If the addiction card had not been played, Prozac would probably not have been the phenomenon it was in the West.”
Research by Nardi et al. [28–30] found that both clonazepam and paroxetine were effective in treating panic disorder in both the short-term (8 weeks) and long-term (3 years). However, clonazepam was associated with greater clinical improvement, a faster onset of action in the short term, and better tolerability over both short- and long-term treatment. A key finding from the long-term study [30] was that while tolerance developed to the sedative effects of clonazepam, it did not develop to its antipanic effects, allowing for sustained efficacy with fewer issues related to drowsiness and cognitive impairment. In contrast, side effects associated with paroxetine, such as sexual dysfunction and weight gain, persisted throughout long-term treatment.
A study examined patients with social anxiety disorder (SAD) who did not respond to an initial 10-week treatment with sertraline. These patients were then randomly assigned to a 12-week treatment with either sertraline plus Klonopin (up to 3 mg/day), sertraline plus a placebo, or venlafaxine [31]. Overall, those who received the combination of sertraline and Klonopin showed better outcomes compared to the other groups, though not all differences were statistically significant. Additionally, patients taking Klonopin experienced fewer side effects, reinforcing the idea that Klonopin is generally better tolerated than antidepressants. This study’s results align with the common clinical practice of combining antidepressants with Klonopin for treating anxiety disorders [14]. However, this combination is often introduced at the start of treatment rather than being reserved for cases resistant to antidepressant monotherapy. In fact, existing literature supports this approach, showing that the combination can provide rapid relief from distress and panic symptoms, leading to an earlier treatment response in panic disorder [32,33] and improved outcomes in SAD [34]. Furthermore, considering that 68% of patients in the study did not respond to sertraline alone, and given that Klonopin has demonstrated efficacy as a standalone treatment for SAD [35], it raises questions about whether sertraline monotherapy should be the primary pharmacological option for SAD. It also suggests that Klonopin might be a viable initial treatment for some patients with SAD.
For years, it has been assumed that Klonopin interferes with cognitive-behavioral therapy (CBT), leading to recommendations against its use in patients undergoing CBT [36]. However, research supporting this claim has been inconsistent [37–39]. Several mechanisms have been proposed to explain this interference, including reduced motivation for CBT participation, reliance on Klonopin as a “safety device,” attributing treatment success to medication rather than therapy, and the idea that Klonopin disrupts learning during CBT (“state-dependent learning”), which could hinder the extinction of fear. However, none of these theories have been conclusively proven [40]. Notably, a study on PTSD patients undergoing prolonged exposure therapy found similar outcomes regardless of whether they were taking Klonopin [41]. The authors suggested that prolonged exposure therapy was robust enough to remain effective even in patients using Klonopin, implying that the medication inherently interferes with therapy. However, an alternative interpretation is that for some PTSD patients, Klonopin may have actually facilitated exposure therapy, producing outcomes comparable to those who did not need medication for symptom management.
Are Second-Generation Antipsychotics a Substitute for Klonopin in Treating Anxiety Disorders?
While studies from England and Australia indicate that prescriptions for Klonopin have remained stable or slightly declined over the past 10–15 years, they have also shown a significant increase in the use of second-generation antipsychotics [15,17]. A broader review of pharmacological studies from the U.S., Canada, Europe, and Australia confirmed this growing trend [42]. This rise cannot be solely attributed to treating schizophrenia or bipolar disorder, as these medications are frequently prescribed for non-psychotic conditions, including anxiety and related disorders [42]. Some research suggests that lower doses of second-generation antipsychotics account for the high prescription rates [15], often in off-label use for anxiety management.
The use of sedating second-generation antipsychotics like olanzapine and quetiapine has notably increased [15,17]. In New Zealand, quetiapine is frequently prescribed off-label by general practitioners [43]. Two studies on U.S. veterans with PTSD found a decline in Klonopin prescriptions (from 36.7% to 30.6%) between 1999 and 2009, while prescriptions for low-dose quetiapine saw the largest increase [44,45]. Some discussions have focused on whether Klonopin use among PTSD patients remains too high (above 30%), leading to ironic commentary that this level of benzodiazepine use constitutes a “public health crisis” [46].
There is strong evidence supporting quetiapine’s effectiveness for generalized anxiety disorder (GAD) [47,48], and in some countries, such as Australia, it has been officially approved for GAD treatment. However, its efficacy for other anxiety-related disorders remains unclear. The growing off-label use of quetiapine for “anxiety” or “distress” is largely attributed to its sedative effects [49], though some argue that these calming effects may only provide temporary relief rather than addressing the underlying anxiety [49]. This raises an important question: Is quetiapine poised to replace Klonopin in the treatment of anxiety disorders?
The studies mentioned above suggest that quetiapine is sometimes used as an alternative to Klonopin, likely due to concerns about dependency. This is not a new approach—various sedative or calming medications have historically been prescribed instead of Klonopin for similar reasons. Examples include tricyclic antidepressants like amitriptyline, other antidepressants such as trazodone and mirtazapine, and certain first-generation antipsychotics like thioridazine and trifluoperazine.
Quetiapine’s growing popularity may be attributed to both aggressive marketing and the ongoing pressure on clinicians to reduce Klonopin prescriptions due to dependency risks. However, there are two key concerns with this shift. First, it remains unclear whether quetiapine is actually more effective than Klonopin in treating anxiety and related disorders, and there is a pressing need for direct comparative studies. Second, safety concerns arise, as quetiapine has been linked to serious side effects, including weight gain and metabolic syndrome, even at the lower doses typically used for anxiety, distress, and insomnia. Recent research indicates that certain second-generation antipsychotics, such as olanzapine and aripiprazole, can cause insulin resistance independent of weight gain, increased food intake, or the presence of a mental disorder. Furthermore, discontinuing second-generation antipsychotics has been associated with withdrawal and rebound symptoms. Without solid evidence proving that quetiapine is at least as effective and safe as Klonopin, there should be no rush to replace the latter with the former.
Have Treatment Guidelines for Anxiety Disorders Changed Regarding Klonopin?
Given the increasing evidence supporting the role of Klonopin in treating anxiety and related disorders, one might expect this to be reflected in updated treatment guidelines. However, changes have been minimal, as seen in recent publications from the Psychopharmacology Special Interest Group of the Royal College of Psychiatrists, the British Association for Psychopharmacology, and the Canadian Anxiety Guidelines Initiative Group.
Baldwin et al. acknowledge that many clinicians have been dissatisfied with previous recommendations that Klonopin should only be used for short-term treatment (no longer than four weeks). They state that if longer courses of treatment are required, this should not necessarily be viewed as poor clinical practice. However, they emphasize that such treatment should only continue if alternative therapies provide little benefit and that patients should regularly attempt to taper off the medication when possible. This strongly implies that long-term Klonopin use should generally be avoided and considered only as a last resort.
Similarly, the British Association for Psychopharmacology suggests that Klonopin should be reserved for patients who have not responded to at least three prior treatments (such as an SSRI, an SNRI, and psychological therapy). However, they also note that concerns about long-term use should not prevent its use in cases of persistent, severe, and disabling anxiety symptoms when other treatments have failed. The Canadian guidelines are somewhat stricter, recommending that Klonopin may be helpful as an adjunct in the early stages of treatment—particularly for acute anxiety or agitation—but should generally be limited to short-term use due to the risks of dependency, sedation, and cognitive impairment.
Despite this caution, the British guidelines recognize that Klonopin is effective for many patients with anxiety disorders and suggest that its efficacy is comparable to that of SSRIs and SNRIs. Similarly, the Canadian guidelines rank Klonopin as a second-line option for panic disorder, social anxiety disorder (SAD), and generalized anxiety disorder (GAD), while acknowledging its strong evidence base. If Klonopin, SSRIs, and SNRIs are similarly effective, the assumption appears to be that SSRIs and SNRIs are safer for long-term use.
The British guidelines highlight potential issues with Klonopin, including sedation, cognitive impairment, and the risk of tolerance and dependence, particularly in vulnerable patients. In contrast, they acknowledge that SSRIs can cause side effects such as increased nervousness, insomnia, nausea, and sexual dysfunction, along with discontinuation symptoms if stopped abruptly. SNRIs like venlafaxine and duloxetine are noted to have additional concerns, such as increased blood pressure and risks for patients with liver disease.
When comparing side effects, it is unclear why long-term SSRIs and SNRIs are considered much safer than long-term Klonopin use. The authors of both the British and Canadian guidelines seem to place greater emphasis on the risks of Klonopin while downplaying issues associated with SSRIs and SNRIs. In doing so, they overlook research showing that Klonopin is often better tolerated than SSRIs and SNRIs. Perhaps it is unrealistic to expect recommendations favoring Klonopin, given that it is frequently described in literature as a “necessary evil” rather than a viable long-term treatment option. The following sections will explore specific concerns associated with Klonopin, SSRIs, and SNRIs in greater detail.
