White Pepper 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 White Pepper interacts with.

In vitro evidence suggests that piperine, a constituent of white pepper, inhibits platelet aggregation. Theoretically, white pepper might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Some anticoagulant/antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
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 the wrinkle with this one: the interaction on file is really about bleeding risk, and abrocitinib (Cibinqo) isn't a blood thinner. It's a JAK inhibitor for eczema. That said, abrocitinib can lower your platelet count on its own, especially in the first few weeks. So the concern isn't that white pepper changes how abrocitinib is broken down. It's that both can nudge you toward easier bleeding or bruising at the same time.

Keep in mind this piperine-and-platelets finding comes only from lab studies, not real people, and the everyday pepper on your dinner is very unlikely to matter. Concentrated piperine supplements are a bigger question mark. If you notice unusual bruising, bleeding gums, or nosebleeds, loop in your pharmacist or doctor before changing anything.

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 White Pepper

What is White Pepper?

  • Digestive upset
  • Seasoning and appetite support
  • Cough and cold remedies (traditional)
  • Minor aches and pains (traditional)
  • Antimicrobial (traditional)

White pepper comes from the same plant as black pepper and is mostly used as a kitchen spice. In normal food amounts it is generally safe for most people, but there is little solid human research supporting its use as a medicine. Talk with your pharmacist or doctor before using concentrated supplements, especially if you are pregnant, breastfeeding, or have a health condition.

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).
