Additionally, it can be prescribed to reduce nightmares and other sleep disturbances associated with post-traumatic stress disorder (PTSD) [4].
How does Prazosin work?
Prazosin belongs to a class of drugs called alpha-blockers [2]. It works by relaxing blood vessels, which lowers blood pressure and improves blood flow [2][3].

In PTSD, its exact mechanism for reducing nightmares is not fully understood but is believed to involve blocking the effects of stress hormones in the brain [4].
