Jackfruit and Sorafenib

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Sorafenib

Sorafenib falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Jackfruit interacts with.

Theoretically, jackfruit latex might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Jackfruit latex, which is the sap from jackfruit bark, contains chemicals that might increase the risk of bleeding. In vitro research shows that jackfruit latex contains a glycoprotein constituent that prolongs the activated partial thrombin time (aPTT) and reduces the activity of blood coagulation factors XIa and alpha-XIIa. Jackfruit latex also contains a protease constituent that has been shown to have fibrinolytic activity in vitro. Other parts of jackfruit, including the fruit and leaves, have not been shown to contain chemicals with fibrinolytic and anticoagulant activity.
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 honest picture for Sorafenib (Nexavar). The concern on file isn't really about how your body processes the drug. Instead, it's about an added bleeding risk. Sorafenib itself can raise the chance of bleeding and bruising, and the worry is that jackfruit latex (the sticky sap from the bark, not the fruit you eat) contains compounds shown in lab studies to thin the blood and slow clotting. Stacked together, these two could in theory make bleeding more likely.

One reassuring point: this is based only on test-tube research, and the plain fruit and leaves haven't shown this clotting effect. So eating jackfruit as a food is very unlikely to be a problem. Concentrated latex-based products are a different story. Before using any such product, please check with your oncologist or pharmacist.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is

From our pharmacist’s overview on the Sorafenib page

“If you're on sorafenib (Nexavar) for cancer, be genuinely careful here, and learn the five major-rated entries first. Most of the 285 ingredients listed either have blood-thinning effects that stack onto sorafenib's bleeding risk (more than 200 do) or affect CYP3A4, the liver enzyme that clears the drug, pushing its level too high or t…”

About Jackfruit

What is Jackfruit?

Jackfruit
  • General nutrition
  • Blood sugar support
  • Digestive health (fiber)
  • Antioxidant support
  • Wound care (traditional, latex/leaves)

Jackfruit is a large tropical fruit that is nutritious and safe to eat as a food, offering fiber, vitamin C, potassium, and antioxidants. While its leaves, seeds, and other parts are used in traditional medicine for things like blood sugar and digestion, strong human evidence for these supplement uses is limited. Talk to your pharmacist or doctor before using concentrated jackfruit products for a health condition.

About Sorafenib

What Is Sorafenib Used For?

Brand name: Nexavar

Sorafenib tablets are approved to treat three types of cancer. The first is unresectable hepatocellular carcinoma (HCC) — liver cancer that cannot be removed with surgery. The second is advanced renal cell carcinoma (RCC) — kidney cancer that has spread or progressed. Both the brand Nexavar and generic sorafenib tablets are approved for these two uses.

The third use is for locally recurrent or metastatic, progressive differentiated thyroid carcinoma (DTC) — thyroid cancer that has spread or worsened and no longer responds to radioactive iodine treatment. Nexavar and sorafenib tablets are both approved for this use as well.
