📚 Sertraline — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Sertraline is a selective serotonin reuptake inhibitor (SSRI) used first-line for depression, panic disorder, OCD, PTSD, and social anxiety. It boosts available serotonin in the synapse and is preferred for its relatively favorable safety profile compared to TCAs and MAOIs. Therapeutic effect takes 2-4 weeks, but suicide risk can rise early as energy returns before mood lifts.
🔑
Key points
Understand these first
Full antidepressant effect takes 2-4 weeks; do not stop early just because mood seems unchanged.
Suicide risk increases in the first weeks of therapy, especially in patients under 25 (black box warning).
Common side effects include nausea, headache, insomnia/somnolence, and sexual dysfunction.
Combining with MAOIs, triptans, St. John's wort, or other serotonergic drugs can cause serotonin syndrome.
May cause hyponatremia (SIADH), particularly in older adults.
✅
Nursing priorities
What to do, in order
Assess suicidal ideation at each visit, especially during the first weeks and after dose changes.
Monitor for serotonin syndrome (agitation, hyperthermia, tremor, hyperreflexia, diarrhea).
Teach the 2-4 week delay so the patient does not stop prematurely.
Instruct to take with food to reduce nausea and at a consistent time daily.
Reinforce never to abruptly discontinue; coordinate a taper with the provider.
🚩
Red flags — report now
Escalate immediately
Serotonin syndrome: high fever, muscle rigidity, agitation, autonomic instability - hold drug and report immediately.
New or worsening suicidal thoughts or behavior - report now.
Never give within 14 days of an MAOI (before or after).
Signs of hyponatremia: confusion, headache, weakness, seizures.

Patient teaching
What patients must know
Expect 2-4 weeks before mood improves; keep taking it daily.
Do not stop suddenly; report worsening mood or suicidal thoughts immediately.
Avoid alcohol and other serotonergic agents including OTC St. John's wort.
Sexual side effects are common and reversible; discuss with the provider rather than stopping.

What are the priority nursing interventions for Sertraline?

What do I need to know about Sertraline for the NCLEX?
Full antidepressant effect takes 2-4 weeks; do not stop early just because mood seems unchanged. Suicide risk increases in the first weeks of therapy, especially in patients under 25 (black box warning). Common side effects include nausea, headache, insomnia/somnolence, and sexual dysfunction. Abrupt discontinuation causes withdrawal/discontinuation syndrome (dizziness, flu-like symptoms, irritability); taper to stop.
What patient teaching is important for Sertraline?
Expect 2-4 weeks before mood improves; keep taking it daily. Do not stop suddenly; report worsening mood or suicidal thoughts immediately. Avoid alcohol and other serotonergic agents including OTC St. John's wort. Sexual side effects are common and reversible; discuss with the provider rather than stopping.
