Interaction report

Jequirity and Nintedanib Esylate

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Jequirity interacts with whole categories of medication. Nintedanib Esylate falls into 2 of those categories, so it can interact with Jequirity in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

1 of 2

Why this applies to Nintedanib Esylate

Nintedanib Esylate falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Jequirity interacts with.

Evidence from in vitro research suggests that constituents of jequirity beans can inhibit platelet aggregation. Theoretically, jequirity might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs. Some anticoagulant or 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 explains PharmD, Clinical Pharmacist

Here's the simple version. Lab studies hint that compounds in jequirity seeds may slow down platelets, the tiny cells that help your blood clot. Ofev (nintedanib) already carries its own bleeding risk on its own, so the worry is that stacking these two together could nudge that risk a little higher, meaning easier bruising, nosebleeds, bleeding gums, or longer bleeding from a cut.

I want to be honest with you though: this concern is theoretical, based only on test-tube research, not real patient cases. That said, jequirity is a genuinely poisonous plant (its abrin toxin is in the same family as ricin), so I would not take it at all, with or without Ofev. Please loop in your doctor or pharmacist before adding any supplement.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Nintedanib Esylate also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

In vitro research shows that jequirity extract inhibits CYP3A4 enzymes. Theoretically, taking jequirity may inhibit the metabolism of CYP3A4 substrates.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Let me be upfront about the biggest issue here: jequirity seeds are extremely poisonous and should never be taken at all. The abrin in them is in the same dangerous family as ricin, so this isn't something I'd ever recommend swallowing, period.

Setting the poison aside, the interaction itself is gentle on paper. Lab studies suggest jequirity might slow down CYP3A4, one of the enzymes that helps clear Ofev from your body. Ofev is an active drug (not a prodrug), so if that enzyme were blocked, levels could creep up and you might see more of its usual side effects, things like diarrhea, nausea, belly pain, or liver enzyme changes. But this is only a theoretical, test-tube finding rated unlikely. Please talk with your doctor or pharmacist before combining anything with Ofev.

From our pharmacist’s overview on the Nintedanib Esylate page

“You take Ofev (nintedanib) to slow lung scarring, and this page deserves a careful read before any supplement joins it. Of the 285 ingredients here, the biggest cluster, over 200, can add to bleeding risk, a real concern since nintedanib itself can make you bleed more easily.”

About Nintedanib

What Is Nintedanib Used For?

Brand name: Ofev

Nintedanib treats certain scarring lung diseases in adults. All the supported products are indicated for idiopathic pulmonary fibrosis (IPF) and for chronic fibrosing interstitial lung diseases (ILDs) with a progressive phenotype (scarring lung disease that keeps getting worse).

Ofev, nintedanib capsules (100 mg and 150 mg) and one other nintedanib capsule product are also indicated to slow the decline in lung function in systemic sclerosis-associated interstitial lung disease (SSc-ILD). The nintedanib esylate capsule label lists only IPF and progressive chronic fibrosing ILDs.
