Black 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 Black Pepper interacts with.

Theoretically, black pepper might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit platelet aggregation. This has not been reported in humans.
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 connection worth knowing. Lab studies suggest piperine, the active part of black pepper, may make platelets a little less sticky, which could nudge up the chance of bleeding. Abrocitinib (Cibinqo) can already lower your platelet counts on its own, so the worry is that the two together might add up and make bleeding or bruising a bit more likely.

I want to be honest about the strength of this, though. It's purely theoretical, based on test-tube work, and hasn't actually been seen in people. The pinch of pepper on your dinner is very unlikely to matter. Concentrated piperine supplements are where I'd be more thoughtful. Watch for easy bruising, nosebleeds, or bleeding gums, and check with your pharmacist before adding a supplement.

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 Black Pepper

What is Black Pepper?

Black Pepper
  • Flavoring and culinary use
  • Digestive complaints like bloating and indigestion
  • Boosting absorption of other supplements
  • Antioxidant and anti-inflammatory support
  • Cold and congestion remedies

Black pepper is a common kitchen spice that is generally safe in the amounts used in food. Its extract, piperine, is mostly added to supplements to help the body absorb other ingredients (like curcumin from turmeric). Strong human evidence for black pepper treating specific health conditions is limited, so use supplement-strength products with care and check with your pharmacist.
