Krill Oil and Lumiracoxib

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Lumiracoxib and Krill Oil in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Krill Oil safety at a glance

Krill Oil overall Use caution Generally well tolerated, but avoid if you have a shellfish allergy and use caution if you have a bleeding disorder.
Pregnancy Use caution Not enough reliable safety data; talk to your doctor before using during pregnancy.
Breastfeeding Use caution Not enough reliable safety data; talk to your doctor before using while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Lumiracoxib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lumiracoxib is filed under 7 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, organic anion transporter 3 (oat3) substrates. Krill Oil has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antidiabetes drugs (moderate) — and none of Lumiracoxib’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

“Lumiracoxib (Prexige) is a COX-2 anti-inflammatory that was withdrawn in several countries over liver injury, which makes the biggest theme on this page the one to respect: 38 ingredients with their own records of liver harm, ashwagandha among them, could stack on top of the drug's hepatic risk.

About Krill Oil

What is Krill Oil?

Krill Oil
  • Heart and cholesterol support
  • High triglycerides
  • Joint pain and inflammation
  • Brain and eye health
  • PMS symptoms
  • General omega-3 supplementation

Krill oil is a source of omega-3 fatty acids (EPA and DHA) bound to phospholipids, which may help absorption. It is most studied for lowering triglycerides and supporting heart health, but the evidence for many other uses is limited. It is generally well tolerated, but people with shellfish allergy should avoid it, and anyone pregnant, breastfeeding, or on blood thinners should check with a pharmacist or doctor first.

Euphausia superba · Euphausiidae · Oil extracted from the whole krill · Softgel capsules, liquid

An interaction check asks whether these two react with each other — it does not ask whether Krill Oil is a good idea for someone in your situation. Here is what our Krill Oil record says about it on its own.

Krill Oil: dosing

There is no single official or standardized dose of krill oil. Products vary in how much EPA and DHA they provide per capsule, so two products may not be equal even at the same number of capsules.The best approach is to follow the directions on the product label and to choose a reputable brand.
