Interaction report

Jequirity and Ticagrelor

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. Ticagrelor 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 Ticagrelor

Ticagrelor 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

First things first: jequirity seeds are genuinely poisonous (they contain abrin, a toxin in the same family as ricin), so this isn't something you should be taking at all. Please don't use it. That said, here's the interaction with Brilinta (ticagrelor) in plain terms.

Ticagrelor is a blood thinner that keeps your platelets from clumping together to form clots. In lab studies, compounds from jequirity also appear to slow platelet clumping. Stacking the two could, in theory, push your bleeding risk higher, think easy bruising, nosebleeds, bleeding gums, or harder-to-stop cuts. This is a theoretical concern based on test-tube research, not strong human evidence, so it's not a reason to panic. The real safety issue here is the seed's toxicity. Please talk with your pharmacist or doctor before combining anything new with ticagrelor.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Ticagrelor 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 explains PharmD, Clinical Pharmacist

First, the big picture: jequirity seeds are genuinely poisonous (they contain abrin, a toxin similar to ricin) and should never be taken at all. So my honest advice has nothing to do with your heart medicine. Please don't use this plant in any form.

That said, here's the lab finding on file. Ticagrelor (Brilinta) is cleared by a liver enzyme called CYP3A4, and test-tube studies suggest jequirity may slow that enzyme down. In theory, that could let ticagrelor build up a bit, which might raise its blood-thinning effect and the chance of bruising, nosebleeds, or other bleeding. This is only weak, lab-based evidence rated as unlikely and minor, so I wouldn't lose sleep over it. The real concern here is the plant's toxicity. If you have any questions about Brilinta, your pharmacist or doctor is the right person to ask.

See Every Supplement That Interacts With Ticagrelor

This page covers Jequirity only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ticagrelor page lists 286 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Grapefruit (major), Piracetam (major) and St. John's Wort (major).

By severity: 5 major · 241 moderate · 40 minor.

From our pharmacist’s overview on the Ticagrelor page

“Grapefruit sits at the top of this list for good reason. Ticagrelor (Brilinta) is cleared by the CYP3A4 enzyme, and grapefruit blocks that enzyme, so drug levels can climb and bleeding becomes more likely.”

Jequirity (Abrus precatorius) is a tropical plant whose bright red, black-tipped seeds contain abrin, one of the most toxic plant proteins known. Despite a long history in traditional medicine, the seeds are dangerously poisonous and there is no reliable evidence that it is safe or effective. It should not be used as a supplement or medicine.

About Ticagrelor

What Is Ticagrelor Used For?

Brand name: Brilinta

Ticagrelor tablets are used to lower the risk of cardiovascular death, heart attack (myocardial infarction), and stroke in adults who have had acute coronary syndrome (ACS) — a group of conditions including unstable angina and heart attack — or who have a history of heart attack. It also reduces the risk of stent thrombosis (a blood clot forming in a coronary stent) in people who have been stented for ACS treatment.

Ticagrelor tablets are also used in people with coronary artery disease (CAD) who are at high risk for a first heart attack or stroke, particularly those with type 2 diabetes. Additionally, Brilinta is approved to reduce the risk of stroke in adults with a mild acute ischemic stroke or a high-risk transient ischemic attack (TIA, or "mini-stroke").
