What the AI-written analysis says
Duloxetine is an antidepressant that may interact with Omega-3 fatty acids, particularly in terms of bleeding risk and serotonin levels. While both substances are commonly used, caution is advised when combining them due to potential interactions.
Duloxetine is a prescription medication. This page describes publicly documented interactions — it can't see your dose, your other prescriptions, or your labs. Discuss any supplement with the prescriber or pharmacist who manages this medication before combining.

Timing
No timing arrangement makes this combination safe — see the warnings above.
Watch out for
- SSRI and SNRI antidepressants lower the serotonin stored in platelets, which platelets need in order to clot. On its own this is linked to a modestly higher bleeding risk. Some supplements also slow clotting or reduce platelet function (for example ginkgo, high-dose fish oil/omega-3, vitamin E, garlic extract, nattokinase, turmeric and ginger), so the effects can add up. Watch for easy bruising, nosebleeds, bleeding gums, or unusually heavy periods, and mention this combination to the prescriber or pharmacist, especially before surgery or dental work, or if an NSAID or blood thinner is also being used.
- Monitor for signs of increased bleeding, especially if taking other medications that affect bleeding risk.
