The APA Practice Guideline also states that although the highest “usual therapeutic dose” for panic disorder is clonazepam 2 mg/d or alprazolam 4 mg/d, “higher doses are sometimes used for patients who do not respond to the usual therapeutic dose.”1
Presumably, an SSRI/benzodiazepine combination should be considered if an SSRI alleviates major depressive disorder but does not alleviate a comorbid panic disorder. However, the APA Practice Guideline does not include studies that investigated this clinical scenario.
Monitor carefully for dependency/abuse
Restricting benzodiazepine use to low doses over a short period of time may decrease the risk of dependence and abuse. However, this practice may also limit or prevent effective treatment for adherent patients with panic disorder who do not adequately respond to SSRI or SNRI monotherapy.
Therefore, clinicians need to carefully differentiate between patients who are adherent to their prescribed dosages and those who may be at risk for benzodiazepine dependence and abuse. Consider using prescription drug monitoring programs and drug screens to help detect patients who “doctor shop” for benzodiazepines, or who could be abusing opioids, alcohol, marijuana, or other substances while taking a benzodiazepine.
