Breadfruit and dabigatran

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to dabigatran

dabigatran falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Breadfruit interacts with.

Theoretically, concomitant use with anticoagulant/antiplatelet drugs might increase the risk of bleeding. In vitro research shows that certain flavonoid constituents from breadfruit root extract can inhibit thromboxane formation and reduce platelet aggregation.
Some of these 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 plain version: dabigatran (Pradaxa) is already a blood thinner, so anything that nudges your blood toward bleeding in the same direction is worth thinking about. The concern here is that some compounds in concentrated breadfruit leaf extracts may make platelets a little less sticky. Stack that on top of dabigatran and, in theory, you could bleed more easily, think easy bruising, nosebleeds, bleeding gums, or blood that takes longer to stop.

That said, this is only a theoretical worry based on lab studies, not real people. Eating breadfruit as food is very unlikely to cause trouble. The bigger question is concentrated leaf teas or supplements. Since dabigatran needs careful handling, please run any breadfruit product by your pharmacist or doctor first.

About Breadfruit

What is Breadfruit?

  • Source of nutrition and energy
  • High blood pressure
  • Diabetes and blood sugar support
  • Inflammation and joint discomfort
  • Skin conditions

Breadfruit is a starchy tropical fruit eaten as a staple food, and its leaves are used in traditional medicine for conditions like high blood pressure and diabetes. As a food it is nutritious and generally safe, but the medicinal use of leaf teas or extracts has very little human research to back it up. Talk with your pharmacist or doctor before using breadfruit products for a health condition.

About Dabigatran

What Is Dabigatran Used For?

Brand names: Pradaxa, Pradax

Dabigatran etexilate capsules are used in adults to reduce the risk of stroke and dangerous blood clots in people with non-valvular atrial fibrillation (an irregular heart rhythm not caused by a heart valve problem). They are also used to treat deep venous thrombosis (DVT — a blood clot in a deep vein) and pulmonary embolism (PE — a blood clot in the lungs), to lower the risk of those clots coming back, and to prevent DVT and PE in adults who have had hip replacement surgery.

In children ages 8 to under 18, dabigatran etexilate capsules are used to treat venous thromboembolic events (VTE — blood clots in the veins) and to reduce the risk of those clots recurring. Pradaxa Oral Pellets — a separate formulation — are indicated for the treatment and prevention of recurrent VTE in younger children ages 3 months to under 12 years.
