Boldo and Elotuzumab

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Elotuzumab

Elotuzumab falls under HEPATOTOXIC DRUGS — the group Boldo interacts with.

Theoretically, taking boldo with hepatotoxic drugs might increase the risk of hepatic injury and disease.
Boldo leaf contains ascaridole, a known liver toxin. Many cases of hepatotoxicity, including elevated liver transaminase levels and jaundice, have been reported in patients taking boldo.
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: Boldo isn't changing how Elotuzumab (Empliciti) works against your myeloma. Elotuzumab is an antibody given by IV, and your immune system handles it, not your liver enzymes. So this isn't the usual "one speeds up or slows down the other" situation.

The real concern is that boldo leaf contains ascaridole, which can be hard on the liver. Cancer treatment can already stress your liver, and your team watches your liver labs closely. Stacking a supplement that may raise those numbers (think fatigue, belly pain, or yellowing of the skin or eyes) just adds avoidable risk. This is theoretical and based on scattered case reports, not strong studies. Still, please check with your oncology team or pharmacist before using any boldo product.

From our pharmacist’s overview on the Elotuzumab page

“Elotuzumab (Empliciti) is an infusion for multiple myeloma, and every one of the 38 supplement interactions on file for it comes down to the same organ: the liver. Each ingredient here can stress or injure the liver on its own, and stacking that risk on top of cancer treatment deserves genuine care.”

About Boldo

What is Boldo?

Boldo
  • Indigestion and bloating
  • Mild constipation
  • Liver and gallbladder support
  • Appetite stimulation
  • Urinary complaints

Boldo is a South American shrub whose leaves are traditionally used for digestive and gallbladder complaints, but good human evidence is very limited. The leaves and oil contain ascaridole, which can be toxic to the liver, so only ascaridole-free products should be used and only for short periods. Talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.
