Olanzapine in the treatment-resistant, combat-related PTSD--a series of case reports

Nightmares and insomnia in combat-related post-traumatic stress disorder (PTSD) might be resistant to treatment with selective serotonin reuptake inhibitors (SSRIs) and benzodiazepines.

We describe five case reports of patients suffering from long-lasting and intractable nightmares and insomnia. They were given different psychotropic agents in past few years, with no improvement in their sleep disturbance. Olanzapine was added to the current treatment regimen.

Both nightmares and insomnia improved rapidly after olanzapine institution in all of five patients. No adverse events of olanzapine were reported.

Olanzapine augmentation might be useful in alleviating treatment-resistant nightmares and insomnia in patients with combat-related PTSD.
