Flaxseed 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 Flaxseed Oil interacts with.

Theoretically, using flaxseed oil in combination with anticoagulant or antiplatelet drugs might have additive effects and increase the risk of bleeding.
Small clinical studies show that consuming flaxseed oil might decrease platelet aggregation and increase bleeding time.
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 explains PharmD, Clinical Pharmacist

Here's the thing to keep in mind with this pairing. Flaxseed oil isn't changing how your body processes abrocitinib, and abrocitinib isn't a prodrug, so we're not talking about the medication getting stronger or weaker. The concern is something simpler: both can nudge you toward easier bleeding. Some small studies suggest flaxseed oil may make platelets a little less sticky, and abrocitinib (a JAK inhibitor) can lower platelet counts, especially in the first weeks of treatment.

Stacked together, that theoretically means a slightly higher chance of bruising, nosebleeds, or bleeding that takes longer to stop. This is based on pharmacology, not strong proof, and food amounts of flax matter less than concentrated supplements. Still, mention it to your pharmacist or doctor before combining them.

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 Flaxseed Oil

What is Flaxseed Oil?

  • Source of omega-3 (ALA) fatty acids
  • Heart and cholesterol health
  • Dry skin and inflammation
  • Constipation
  • General wellness

Flaxseed oil is a plant-based source of the omega-3 fatty acid ALA, which the body can partly convert to the omega-3s found in fish oil. It may help support heart health and provide healthy fats, but evidence for most specific health claims is limited or mixed. It is generally well tolerated, but talk to your pharmacist or doctor before starting, especially if you are pregnant or have a bleeding risk.

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).
