Camphor 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 Camphor interacts with.

Theoretically, concomitant use of camphor with other hepatotoxic drugs might increase the risk of liver damage.
There have been a few case reports of transient elevations in liver enzymes in adults after oral or topical use of camphor. There has also been one case of hepatotoxicity in an infant after topical camphor use.
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 short version: this is a theoretical concern, not something proven to happen with Empliciti. The worry is simply that camphor has been linked, in a handful of case reports, to mild and usually temporary bumps in liver enzymes. Elotuzumab itself can occasionally stress the liver too, so the idea is that piling two liver-taxing things together might add up.

What this means for you: camphor in normal rub-on amounts is unlikely to cause real trouble, and elotuzumab isn't activated or changed by camphor, so this isn't a strong chemical clash. The bigger rule still stands: never swallow camphor, since it's toxic by mouth. Since your team already tracks your liver labs during treatment, just mention any camphor products you use so they can keep an eye out.

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 Camphor

What is Camphor?

  • Muscle and joint aches
  • Cough and chest congestion
  • Itching and skin irritation
  • Cold sores or minor wounds
  • Counterirritant for pain

Camphor is a strong-smelling compound from the camphor tree (or made synthetically) that is used in many topical rub-on products for muscle aches, itching, and chest congestion. It can be helpful for these uses when applied to the skin in small, regulated amounts, but it is toxic and potentially deadly if swallowed, so it should never be taken by mouth. Keep camphor products away from children and check with a pharmacist before use.
