Sertraline, sold as Zoloft, is a widely used SSRI (selective serotonin reuptake inhibitor) for depression, anxiety, and related conditions. It works by raising serotonin activity in the brain, which is effective but also explains its main risk: combining it with other serotonin-raising medicines can cause serotonin syndrome. Knowing the key sertraline interactions and side effects helps you take it safely.
Key takeaways about sertraline
- Sertraline (Zoloft) is an SSRI used for depression and anxiety.
- Combining it with other serotonin-raising drugs can cause serotonin syndrome.
- It should never be taken with MAOI antidepressants.
- With blood thinners or NSAIDs it can raise the risk of bleeding.
- Do not stop it suddenly; a gradual taper avoids withdrawal-like symptoms.
Sertraline interactions to review
The most important interactions raise serotonin activity. These include MAOI antidepressants (never combined with sertraline), other antidepressants, the pain medicine tramadol, migraine triptans, and the herbal supplement St. John's wort. Sertraline can also increase bleeding risk when taken with blood thinners such as warfarin, antiplatelet drugs, or regular NSAIDs like ibuprofen. The exact risk depends on your full list and doses, so ask a pharmacist to check it before adding anything new.
Side effects and warning signs
- Nausea, diarrhea, or stomach upset, often easing over a few weeks.
- Trouble sleeping, drowsiness, dizziness, or headache.
- Sexual side effects such as reduced desire or difficulty.
- Warning signs of serotonin syndrome: agitation, fast heartbeat, sweating, shivering, muscle twitching — seek urgent care.
This is not a complete list. Antidepressants carry a warning about increased suicidal thoughts in young people, especially early in treatment, so watch for mood changes and keep in close contact with the prescriber at the start.
How MedSafeScan helps
MedSafeScan lets you keep sertraline alongside your other prescriptions, OTC products, and supplements — including pain relievers and St. John's wort — so overlapping serotonin or bleeding risks are easier to spot and discuss with a pharmacist. Treat any interaction result as a starting point for a professional conversation, not a final decision.

Quick answers
What should you not take with sertraline?
Avoid combining sertraline with MAOI antidepressants, and be cautious with other medicines that raise serotonin — such as other antidepressants, tramadol, triptans for migraine, and the supplement St. John's wort — because together they can cause serotonin syndrome. Blood thinners and regular NSAIDs can also raise bleeding risk. Have a pharmacist review your full list.
What is serotonin syndrome and what are the warning signs?
Serotonin syndrome is a potentially serious reaction from too much serotonin activity, usually when serotonin-raising drugs are combined. Warning signs include agitation, confusion, fast heartbeat, high blood pressure, heavy sweating, shivering, muscle twitching or stiffness, and diarrhea. Severe cases are a medical emergency — seek urgent care.
What are the common side effects of sertraline?
Common effects include nausea, diarrhea, trouble sleeping, drowsiness, dizziness, and sexual side effects. Many ease over the first few weeks. Do not stop sertraline suddenly, as that can cause withdrawal-like symptoms; your prescriber will usually taper the dose. Read your product's patient information for the full list.
