Recommendations

  • Consult with a healthcare provider before starting Omega-3 while on Sertraline.
  • Consider monitoring for any unusual side effects or interactions.

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.
  • If experiencing any unusual bleeding or bruising, consult a healthcare provider immediately.
