How Prozac Works
Prozac, or fluoxetine (the generic term for the brand name), works by increasing the activity of a chemical called serotonin in the brain.
Prozac side effects have included violent behavior, either harming themselves or others. Some users developed a serious side effect known as akathisia, which could lead to violent or suicidal behavior among a small percentage of users.
Hundreds of lawsuits alleging Prozac has caused suicide and violent behavior have been filed against Eli Lilly.
