Syrian Rue 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 Syrian Rue interacts with.

Theoretically, high doses of Syrian rue might increase the risk of liver damage when taken with hepatotoxic drugs.
Cases of hepatotoxicity and hepatic failure have been reported in patients who ingested a large quantity (up to 100 grams) of Syrian rue seeds.
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 concern with combining Syrian Rue and Elotuzumab (Empliciti). This isn't about one changing how the other is processed. Elotuzumab is a monoclonal antibody, so it doesn't rely on liver enzymes the way many pills do. Instead, the worry is that both can be hard on the liver. Syrian Rue, especially in large or concentrated seed amounts, has been linked to serious liver injury, and cancer treatment regimens can already stress the liver.

I want to be honest that this is theoretical, based on how these things work rather than proven cases of the two together. Still, stacking two possible liver stressors isn't worth the gamble. Watch for yellowing skin or eyes, dark urine, belly pain, or unusual tiredness, and please talk with your oncology team before adding Syrian Rue.

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 Syrian Rue

What is Syrian Rue?

  • Traditional remedy for digestive complaints
  • Used as a sedative or for mood
  • Antimicrobial and antiparasitic folk use
  • Used as a dye and incense
  • Recreational psychoactive use

Syrian Rue (Peganum harmala) is a traditional plant whose seeds contain potent compounds called harmala alkaloids, including MAO-inhibiting harmine and harmaline. There is little reliable human evidence that it safely treats any condition, and it carries real risks of toxicity, so it is not recommended for self-treatment. Talk to a pharmacist or doctor before considering it.
