Objective:
This study evaluated and compared the effectiveness and tolerability of klonopin against other benzodiazepines in patients diagnosed with anxiety disorders.
Methods:
Participants included individuals over 20 years old diagnosed with an anxiety disorder according to the DSM-IV-TR criteria. All participants were taking a single type of antidepressant and were prescribed one of three oral benzodiazepines: klonopin, alprazolam, or lorazepam. Clinical outcomes were assessed at baseline and week 6 using the Clinical Global Impression-Severity Scale (CGI-S), Clinical Global Impression-Anxiety Scale (CGI-anxiety), and Clinical Global Impression-Sleep Scale (CGI-sleep). The primary outcome was the mean change in CGI-S scores from baseline to week 6, while changes in CGI-anxiety and CGI-sleep scores served as secondary outcomes. Benzodiazepine doses were converted into lorazepam-equivalent doses based on established equivalency criteria (alprazolam 0.25 mg = klonopin 0.5 mg = lorazepam 1.0 mg). Adverse events were recorded using the National Cancer Institute Common Toxicity Criteria (version 3.0). The study adhered to the Declaration of Helsinki and good clinical practices and was approved by the institutional review board at each site.
Results:
A total of 180 patients participated in the study, with no significant differences in demographic or baseline clinical characteristics between the benzodiazepine groups. Although the klonopin online group had a slightly younger mean age (44.2 ± 16.3 years) compared to the alprazolam (49.4 ± 15.0 years) and lorazepam (50.3 ± 16.7 years) groups, this difference was not statistically significant. At the end of six weeks, all three benzodiazepine groups demonstrated significant improvements in CGI-S, CGI-anxiety, and CGI-sleep scores (p < 0.001), with no significant differences in the magnitude of improvement between the groups. However, klonopin had a significantly lower incidence of adverse events (26.7%) compared to alprazolam (48.4%) and lorazepam (43.9%).
Conclusion:
Klonopin was found to be as effective as alprazolam and lorazepam for treating anxiety disorders. Additionally, its safety profile was superior, with fewer reported adverse events compared to the other benzodiazepines.

The doses of the three benzodiazepines (BZDs) were compared using lorazepam-equivalent values. The alprazolam group required significantly higher baseline, maximum, week 6, and average doses compared to the klonopin and lorazepam groups, with no notable differences observed between the latter two (Table 4).
Table 5 outlines the adverse event rates across the BZD groups. The overall incidence of adverse events was significantly lower in the cheap klonopin group (26.7%) compared to the alprazolam (48.4%) and lorazepam groups (43.9%) (p < 0.05). Somnolence was significantly more frequent in the alprazolam group (35.9%) than in the klonopin (9.3%) and lorazepam (14.6%) groups (p < 0.001). All reported side effects were mild, with no serious adverse events observed.
Discussion:
This study aimed to compare the efficacy and safety of alprazolam, klonopin, and lorazepam in patients with anxiety disorders who were also on a concurrent antidepressant. Consistent with prior research, all three BZDs significantly reduced anxiety symptoms from baseline, with no differences in effectiveness between the agents. However, given the perception of BZDs as a “necessary evil,” it is advised to prescribe the lowest effective dose. Notably, buy klonopin overnight required significantly lower doses at baseline, at week 6, and overall compared to alprazolam and lorazepam. While lorazepam-equivalent conversions were based on widely recognized criteria (alprazolam 0.25 mg = klonopin 0.5 mg = lorazepam 1.0 mg), there remains some debate regarding these calculations, warranting cautious interpretation of the results.
The side effect profiles observed in this study align with prior findings. All side effects were mild, and no serious adverse events were reported. klonopin showed a significantly lower overall incidence of adverse events compared to the other BZDs. This may be attributed to klonopin’s lower lipid solubility and slower elimination half-life, which likely reduced side effects and interdose withdrawal symptoms, commonly seen with high-potency, short-acting BZDs like alprazolam. klonopin’s lack of interaction with antidepressants could also explain its superior tolerability, particularly since all participants were on concomitant antidepressants.
Somnolence was more frequently reported in the alprazolam group, likely due to the higher doses prescribed, as higher BZD doses are known to increase the risk of this side effect.
Study Limitations:
Several limitations should be considered. First, the naturalistic study design may have introduced biases, as treatment group assignments were non-random and ratings were unblinded. Second, the study included only two assessment points over a relatively short six-week period. klonopin’s long half-life raises concerns, as withdrawal symptoms can emerge and persist for months, which would require a longer-term study to assess. Additionally, although the difference was not statistically significant, the klonopin without prescription group had a younger mean age than the alprazolam and lorazepam groups, potentially introducing bias into the findings.
The unequal sample sizes across the three groups present a limitation in this study. Additionally, the lorazepam group had significantly fewer patients with panic disorder compared to the other groups, which could affect the results, as the effectiveness of benzodiazepines (BZDs) may vary based on the type of anxiety disorder. While demographic differences among the groups were not statistically significant, there was a trend toward an age difference (p=0.07), which could have reached statistical significance with a larger sample size. The study also lacked information on patients’ life events and somatic disorders in the demographic data. Moreover, psychological and physical dependence, which is not uncommon in patients using BZDs, was not addressed.
The inclusion of all anxiety-spectrum disorders and more than 10 types of antidepressants with varying doses further complicates the interpretation, as these medications have diverse anti-anxiety effects. The specific interactions between selective serotonin reuptake inhibitors (SSRIs) and the BZDs (alprazolam, clonazepam, and lorazepam) could not be excluded. Changes in Clinical Global Impression-Severity (CGI-S), CGI-Anxiety, and CGI-Sleep scores were used as primary measures of efficacy, but more detailed scales, such as the Hamilton Anxiety Rating Scale (HAMA) and Hamilton Depression Rating Scale (HAMD), could have provided additional insights. One notable omission was the lack of data on klonopin’s muscle relaxation effects, a known side effect. Furthermore, all participants were Korean, which limits the generalizability of the findings to other populations. Ethnicity-specific studies are needed, as benzodiazepine metabolism can vary due to cytochrome P450 polymorphisms.
Clinical Implications:
Despite these limitations, the study has notable clinical implications. To the best of our knowledge, no prior research has directly compared the efficacy and tolerability of these BZDs in patients taking newer antidepressants, such as SSRIs and SNRIs. While the uniform Korean sample is a limitation, it is also a strength, as evidence suggests that benzodiazepine metabolism can differ across ethnic groups. The comparable demographic characteristics, baseline anxiety severity, and types of concomitant antidepressants among the treatment groups reduce the risk of confounding factors.
Although order clonazepam was originally approved as an anti-epileptic, prior studies have demonstrated its efficacy in various psychiatric conditions, including social anxiety disorder and panic disorder. This study reaffirms that alprazolam, klonopin, and lorazepam are equally effective in treating anxiety disorders and extends previous findings by assessing their use alongside newer antidepressants. Notably, klonopin may offer unique benefits in specific conditions, such as social anxiety or panic disorder, warranting further research.
In conclusion, the study suggests that klonopin may be a suitable treatment option for anxiety disorders in patients using concomitant antidepressants. It is effective at lower doses and has a more favorable side effect profile compared to lorazepam and alprazolam.
