Red Sandalwood and Tebentafusp-tebn

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Tebentafusp-tebn and Red Sandalwood in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Tebentafusp-tebn

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tebentafusp-tebn is filed under 2 classifications — qt interval-prolonging drugs, hepatotoxic drugs. Red Sandalwood has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and lithium (moderate) — and none of Tebentafusp-tebn’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Tebentafusp-tebn page

“If you are receiving tebentafusp-tebn (Kimmtrak) for uveal melanoma, its supplement interactions deserve genuine caution, and the nine major-rated ones deserve it most. Every one of the 50 flagged ingredients does one of two things: 38 can add stress to the liver, and 13 can prolong the QT interval, the heart's electrical recovery time…”

About Red Sandalwood

What is Red Sandalwood?

  • Skin care and complexion
  • Acne and skin blemishes
  • Inflammation and minor wounds
  • Digestive complaints (traditional use)
  • Coloring and flavoring agent

Red Sandalwood (Pterocarpus santalinus) is a hardwood used in traditional medicine and in skin and cosmetic preparations, valued for its red pigment and astringent properties. Solid human evidence for its health benefits is very limited, and most claims come from traditional use or laboratory studies. If you want to try it, talk with your pharmacist or doctor first, especially before taking it internally.

Pterocarpus santalinus · Fabaceae · Heartwood (and wood powder/extract) · Wood powder, paste, decoctions, extracts, and as an ingredient in skin and cosmetic preparations

An interaction check asks whether these two react with each other — it does not ask whether Red Sandalwood is a good idea for someone in your situation. Here is what our Red Sandalwood record says about it on its own.
