Can I take Vascepa (icosapent ethyl) and fish oil together?
Vascepa is a purified form of omega-3 (eicosapentaenoic acid, EPA). Many over-the-counter fish oil supplements also contain omega-3s (often a mix of EPA and DHA). Taking them together means you may be increasing your total omega-3 intake. In some cases that’s done intentionally, but it can also raise the risk of side effects that are dose-related.
What’s the main risk of combining them?
The most common concerns with higher omega-3 dosing are:
- Easy bruising or increased bleeding tendency, especially if you also take blood thinners (like warfarin) or antiplatelet medicines.
- GI side effects (like nausea, stomach upset, reflux) that can get worse as dose increases.
If you are on any anticoagulant/antiplatelet therapy, or you have a bleeding disorder, combining products should be coordinated with your clinician.
How do I know if I’m doubling too much?
Check the label of your fish oil for how much EPA (and DHA) it contains per serving. Vascepa’s EPA content is fixed by the prescription product, so adding fish oil can increase your total EPA (and possibly DHA). Ask your prescriber or pharmacist to compare your total EPA amount and set a safe target.
Is there ever a reason to use both?
Sometimes clinicians add an OTC omega-3 for reasons like broader omega-3 coverage, but Vascepa is already an omega-3 therapy with a specific dosing purpose. If your goal is triglyceride lowering, you usually want to avoid “stacking” omega-3 products without a plan, since more isn’t always better.
What should you do before starting or combining?
- Tell your clinician/pharmacist you’re taking Vascepa and the exact fish oil product (brand and label amounts).
- Don’t adjust your doses on your own.
- Get medical advice urgently if you develop unusual bleeding (nosebleeds, blood in urine/stool, heavy bruising) or severe GI symptoms.
What if you’re taking blood thinners?
Combining Vascepa with fish oil is especially important to review if you take warfarin, apixaban, rivaroxaban, clopidogrel, aspirin (or similar). The combined omega-3 intake can increase bleeding risk.

Bottom line
You can only decide safely after checking your fish oil’s EPA/DHA amounts and your other medications. Because Vascepa plus fish oil can increase total omega-3 dose and potentially bleeding risk, confirm the plan with your clinician or pharmacist rather than combining on your own.
If you tell me (1) the fish oil brand/label EPA amount per serving and (2) whether you take aspirin, clopidogrel, warfarin, or any other blood thinner, I can help you think through what to ask your doctor.
