Sertraline + St. Johns Wort
STOP — Contraindicated
🔴 STOP — Contraindicated. Do not take St. Johns Wort with Sertraline. This combination can cause serious harm or death.
Evidence level: STRONG
What this interaction means
NEVER take St. John's Wort with Zoloft. Both boost serotonin, risking potentially fatal Serotonin Syndrome — confusion, rapid heart rate, seizures.
How it works (mechanism)
St. John's Wort increases serotonin via MAO inhibition and reuptake inhibition. Combined with SSRI → Serotonin Syndrome risk.
Practical advice
Do NOT take St. Johns Wort and Sertraline together under any circumstances. If you are currently taking both, contact your doctor or pharmacist immediately — do not stop either medication abruptly without medical guidance.
Timing
Take Sertraline at the same time each day as prescribed. St. Johns Wort can be taken at any convenient time — morning with breakfast is most common. Some botanicals (St. John's Wort especially) have serotonergic activity and must NOT be combined with SSRIs. If you notice increased drowsiness or agitation, shift the botanical to a different time or discuss discontinuation with your prescriber.
Risk factors
Risk increases with higher doses of either substance, older age, liver or kidney impairment, and concurrent use of other serotonergic or CNS-depressant substances.
Symptoms to watch for
Agitation, confusion, rapid heartbeat, high blood pressure, dilated pupils, muscle twitching, diarrhea, high body temperature, seizures. Seek emergency care immediately.
