A 22-year-old client is starting sertraline for major depressive disorder. Which statement shows correct understanding of the teaching?
1I will take sertraline only on days when my symptoms are severe and skip it when my mood improves.
2I will take it daily, report worsening mood or suicidal thoughts promptly, and not stop it abruptly.✓ Correct answer
3If I develop agitation, fever, or diarrhea after using dextromethorphan, I will take the next dose early.
4If I do not feel better after three days, I will double the dose until the antidepressant effect begins.
Explanation
Sertraline is taken consistently, and antidepressant benefit is not immediate. New or worsening suicidal thoughts, unusual agitation, or clinical deterioration require prompt reporting, especially early in treatment or after a dose change. Abrupt discontinuation can cause a discontinuation syndrome. Agitation, fever, diarrhea, or neuromuscular changes after another serotonergic drug may signal serotonin syndrome and require urgent assessment rather than another dose.
Clinical reasoning Sertraline increases serotonergic activity. Early monitoring focuses on clinical worsening or suicidality, while combinations with other serotonergic agents can produce serotonin syndrome.
Decision rule Take sertraline every day as prescribed, report dangerous mood or behavior changes promptly, and taper only with prescriber guidance. Agitation plus autonomic or neuromuscular symptoms requires urgent evaluation.
