Investigating the safety and tolerability of single-dose psilocybin for post-traumatic stress disorder: A nonrandomized open-label clinical trial
This Phase II, nonrandomized open-label trial (n=22) tested a single 25 mg dose of psilocybin with psychological support in adults with PTSD. It found the treatment to be safe and well-tolerated, with common side effects such as headache, nausea, crying, and fatigue resolving quickly. Clinically meaningful reductions in PTSD symptoms were observed at weeks 4 and 12, alongside improvements in functioning and quality of life.

Measures Used

Clinician-Administered PTSD Scale for DSM-5
The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) is often considered the gold standard in PTSD assessment. The 30-item structured interview was developed by staff at the U.S. Department of Veterans Affairs National Centre for PTSD. CAPS can be used to make a current diagnosis, lifetime diagnosis or assess PTSD symptoms over the past week in accordance with DSM-5 criteria.
