Introduction
Sertraline (Zoloft) is one of the most prescribed antidepressants in the United States, used for depression, anxiety disorders, OCD, PTSD, and premenstrual dysphoric disorder.
How Sertraline Works
As a selective serotonin reuptake inhibitor (SSRI), sertraline increases serotonin availability in the brain by blocking its reabsorption into the presynaptic neuron.
What Conditions Does It Treat?
FDA-approved uses include major depressive disorder, panic disorder, social anxiety disorder, OCD, PTSD, and PMDD. Off-label uses include generalized anxiety and binge eating disorder.
Starting Sertraline
Typical starting dose is 25–50 mg daily. Allow 4–6 weeks to assess full therapeutic effect. Do not stop abruptly — taper under physician supervision.
Common Side Effects
Nausea, diarrhea, insomnia, sexual dysfunction, and dry mouth are most common, especially in the first 2 weeks of treatment.
What to Expect in the First 4 Weeks
Initial side effects often improve after 1–2 weeks. Mood improvement may begin around week 2–3, with full effect at 4–8 weeks.
Drug Interactions
Avoid concurrent use with MAO inhibitors, pimozide, and other serotonergic agents. Use with caution alongside NSAIDs and anticoagulants due to bleeding risk.
Stopping Sertraline Safely
Never stop sertraline abruptly. Gradually taper the dose over several weeks under medical supervision to avoid discontinuation syndrome.
Conclusion
Sertraline is a well-tolerated, effective first-line treatment for depression and several anxiety disorders. Consistent daily use and open communication with your provider are key to success.
