Sertraline is indicated for a wide range of psychiatric and related conditions, leveraging its serotonin-modulating effects:

• Panic Disorder: Controls panic attacks and anticipatory anxiety in adults, improving daily functioning, with evidence from anxiety disorder studies.
• Post-Traumatic Stress Disorder (PTSD): Treats PTSD in adults, reducing flashbacks and hyperarousal, supported by trauma-focused research.
• Social Anxiety Disorder (SAD): Alleviates social phobia symptoms in adults, enhancing social interaction, per behavioral therapy studies.
• Premenstrual Dysphoric Disorder (PMDD): Manages PMDD symptoms (e.g., mood swings, irritability) in women, often with intermittent dosing, supported by gynecologic psychiatry data.
• Generalized Anxiety Disorder (GAD): Used off-label to treat GAD, reducing excessive worry, with emerging evidence from anxiety research.
• Eating Disorders: Investigated off-label for bulimia nervosa and binge-eating disorder, improving impulse control, with data from eating disorder cohorts.
• Chronic Pain with Depression: Employed off-label to manage depression associated with chronic pain (e.g., fibromyalgia), enhancing pain tolerance, supported by pain management studies.
• Autism Spectrum Disorder (ASD): Explored off-label in children with ASD to reduce repetitive behaviors and anxiety, with preliminary pediatric psychiatry findings.
