PTSD Nightmare Case Continued Alprazolam While Clonidine Was Interrupted and Resumed
A PTSD case linked nightmare recurrence and resolution to interruption and resumption of clonidine while alprazolam remained part of treatment. It does not establish that alprazolam caused or prevented the nightmares.

The medication sequence
Bange and Melvin described an inpatient with PTSD and bipolar disorder whose existing regimen included sertraline, lamotrigine, alprazolam, and clonidine. Clonidine was initially omitted because its home dose could not be confirmed after hours; the other home medications were continued.
Nightmares returned on the second hospital day. Clonidine was then resumed after dose confirmation, and the patient no longer reported nightmares from the next day onward. A later telephone contact described continued absence of nightmares while taking clonidine.
What the sequence supports
The interruption and resumption provide a temporal observation consistent with a clonidine effect in this patient. Continued alprazolam use is part of the background against which the change occurred, rather than the medication change singled out by the report.
This remains an uncontrolled single case. Inpatient circumstances, concurrent medications, self-report, and lack of standardized blinded comparisons limit causal certainty. The authors’ suggested sleep and memory mechanisms were not directly measured in the patient.
Why it matters to forensic review
A symptom appearing in a person prescribed a benzodiazepine is not automatically a benzodiazepine adverse effect. The chronology of omitted and restarted medications may provide a more specific hypothesis.
The case does not establish a general treatment preference, comparative efficacy against benzodiazepines, or a population response rate. Its useful lesson is the need to reconcile the complete regimen before attributing a changing symptom to one familiar drug class.
