The study looks at how well a medicine called **fluoxetine** works for people with PTSD (Post-Traumatic Stress Disorder). PTSD is a condition that can happen after experiencing something very scary or traumatic. Fluoxetine is a type of drug known as an **antidepressant**, which is often used to help people feel better when they are sad or anxious. This study is called a **Phase 2 randomized, double-blinded, placebo-controlled trial**. This means some people will get the real medicine, and some will get a fake pill, but neither the participants nor the researchers will know who gets which until the study ends.

The study lasts for about *16 weeks*, including time for safety checks. Participants must not have used fluoxetine for PTSD recently. If interested in participating, complete a form on the study website.
