Drug class: Selective Serotonin Reuptake Inhibitor (SSRI) antidepressant

Overview

Prozac (fluoxetine) is a prescription medication used to treat depression, obsessive-compulsive disorder (OCD), bulimia nervosa, panic disorder, and premenstrual dysphoric disorder (PMDD). It belongs to a class of medicines called selective serotonin reuptake inhibitors (SSRIs), which help to increase the levels of serotonin, a natural substance in the brain that helps maintain mental balance. Prozac works by blocking the reabsorption (reuptake) of serotonin in the brain, making more serotonin available to improve mood and reduce symptoms of anxiety and depression. It may take several weeks to feel the full benefit of this medication. Key points for patients: Take Prozac exactly as prescribed, do not stop suddenly without consulting your doctor, and report any unusual mood changes or side effects.
