Selective serotonin reuptake inhibitor
Fluoxetine (Prozac) and paroxetine (Paxil) are the only medications the United States Food and Drug Administration has approved for treating post-traumatic stress disorder (PTSD).  Medications alone usually will not cure PTSD; they need to be combined with counseling.  Except for Prozac and Paxil, most other SSRIs do not seem to help PTSD.
