Krill Oil and Abrocitinib

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Abrocitinib

Abrocitinib falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Krill Oil interacts with.

Theoretically, krill oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Taking high doses of omega-3 fatty acids from fish oil can modestly decrease platelet aggregation. Since krill oil also contains these fatty acids, taking high doses of krill oil might also inhibit platelet aggregation. Theoretically, taking high doses of krill oil with antiplatelet or anticoagulant drugs might increase the risk of bleeding. However, the omega-3 content of krill oil is much lower than that of fish oil.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's something worth knowing about this pair. Abrocitinib (Cibinqo) can lower your platelet count, especially in the first few weeks of treatment, which on its own can nudge up your bleeding risk. Krill oil, in high doses, may slightly reduce how well platelets clump together to form clots. Put the two together and you could, in theory, see a bit more bruising, nosebleeds, or bleeding gums.

That said, this is a theoretical concern based on how these work, not strong proof. Krill oil also carries less omega-3 than fish oil, so normal doses are unlikely to cause trouble. Still, since abrocitinib already affects platelets, it's smart to mention your krill oil to your pharmacist or doctor and watch for any easy bruising or unusual bleeding.

From our pharmacist’s overview on the Abrocitinib page

“Bleeding is where I'd focus first with abrocitinib (Cibinqo), an eczema pill that can itself lower platelet counts. Of the 290 supplements and herbs with an interaction on file, 202 have blood-thinning or antiplatelet activity, and two of the three major-rated entries, danshen and piracetam, sit in that group.”

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.

About Abrocitinib

What Is Abrocitinib Used For?

Brand name: Cibinqo

Cibinqo (abrocitinib) is used to treat moderate-to-severe atopic dermatitis (eczema) in adults and children 12 years of age and older. It is specifically for people whose eczema has not been adequately controlled with other systemic (whole-body) treatments, including biologics, or when those treatments are not a safe option.

Cibinqo is not recommended to be used at the same time as other JAK inhibitors, biologic immunomodulators, or other immunosuppressants (medicines that reduce immune system activity).
