Buchu and Defibrotide Sodium

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Defibrotide Sodium

Defibrotide Sodium falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Buchu interacts with.

Buchu may have antiplatelet effects. Theoretically, buchu may enhance the effects of anticoagulant or antiplatelet drugs and increase the risk of bleeding in some patients. 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: defibrotide is a clot-preventing medicine given in the hospital to treat a serious liver complication after a stem-cell transplant. Buchu, on its side, is thought to have mild blood-thinning (antiplatelet) properties. Stack the two together and the worry is additive: more thinning, which can mean a higher chance of bruising or bleeding, like nosebleeds, bleeding gums, or harder-to-stop bleeding.

I'll be honest with you though, this concern is theoretical and rests on weak, anecdotal evidence for buchu, not solid studies. Also, defibrotide is only used in a closely monitored hospital setting, so your care team is already watching for bleeding. Still, don't add buchu (or any supplement) without telling your doctor or pharmacist first so they can keep you safe.

From our pharmacist’s overview on the Defibrotide Sodium page

“Defibrotide (Defitelio) is an intravenous drug for severe veno-occlusive disease of the liver after a stem cell transplant, and part of how it works is by reducing the blood's tendency to clot. That makes bleeding the single thread running through this entire list, and it deserves real care.”

About Buchu

What is Buchu?

Buchu
  • Urinary tract complaints
  • Diuretic (increasing urine flow)
  • Bloating and fluid retention
  • Mild digestive upset
  • Antimicrobial/antiseptic use
  • Flavoring and fragrance

Buchu is a fragrant South African shrub whose leaves are traditionally used for urinary and bladder complaints and as a diuretic. Solid human studies are lacking, so its benefits are largely unproven, and it should be avoided in pregnancy and breastfeeding. Talk to a pharmacist or doctor before using it, especially if you have kidney or liver problems.

About Defibrotide Injection

What Is Defibrotide Injection Used For?

Brand name: Defitelio

Defitelio (defibrotide injection) is used to treat hepatic veno-occlusive disease (VOD) — also called sinusoidal obstruction syndrome (SOS) — in adult and pediatric patients. This is a serious condition where small blood vessels in the liver become blocked, most often after a hematopoietic stem-cell transplant (HSCT).

Defitelio is specifically indicated when VOD is accompanied by kidney dysfunction or pulmonary (lung) dysfunction, making it a treatment for one of the most severe forms of this complication.
