Which agent is generally avoided in PTSD due to the risk of dependence?

• A. Prazosin
• B. Benzodiazepines
• C. SSRIs
• D. SNRIs

Answer: (B)

In PTSD, the goal is to choose medications that support long-term recovery without introducing new risks that can complicate treatment. Benzodiazepines fit poorly for this, because they carry a real risk of dependence and withdrawal, can cause sedation and cognitive slowing, and may be misused in populations with trauma and possible substance use histories. More importantly for PTSD care, they can blunt emotional processing and interfere with exposure-based therapies that rely on patients engaging fully with feared memories and cues. This makes benzodiazepines less desirable as a routine pharmacologic option.

By contrast, selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors are favored as first-line treatments because they help reduce a broad range of PTSD symptoms over time and are safer for long-term use. Prazosin is often used specifically for PTSD-related sleep disturbances and nightmares, addressing a targeted symptom cluster without the same risk of dependence.
