Sertraline (Zoloft) is a selective serotonin reuptake inhibitor (SSRI) and a first-line treatment for major depressive disorder, anxiety disorders, OCD, PTSD, panic, and PMDD. Key teaching: (1) it must be taken consistently, with full antidepressant effect taking 4 to 6 weeks; partial improvement may begin in 1 to 2 weeks; (2) FDA boxed warning for increased suicidal ideation in patients under age 25 — monitor mood and report new or worsening depression, suicidal thoughts, agitation, panic, hostility, akathisia, or impulsivity especially in the first weeks and after dose changes; have a safety plan; (3) serotonin syndrome with combinations such as triptans, MAOIs, tramadol, meperidine, dextromethorphan, ondansetron, linezolid, methylene blue, St John wort, recreational MDMA, other SSRIs/SNRIs/TCAs; recognize hyperreflexia, clonus, agitation, autonomic instability; (4) common side effects — nausea, headache, insomnia or somnolence, sexual dysfunction (decreased libido, anorgasmia), GI upset, weight changes; (5) discontinuation syndrome with abrupt stop especially short-half-life agents (paroxetine) — flu-like, dizziness, brain zaps, anxiety, insomnia; taper gradually; (6) avoid alcohol; (7) hyponatremia (SIADH) and bleeding risk especially with NSAIDs/anticoagulants; (8) report pregnancy because of risk-benefit reassessment. Doubling, PRN use, and stopping early are unsafe.
