HelloPharmacist Bottom Line
Our Pharmacist Explains
What is this? The interaction data in the HelloPharmacist supplement database is licensed from Natural Medicines Pro by TRC Healthcare (Therapeutic Research). HelloPharmacist pharmacists often add our own analysis and context on top of that licensed data — such as this Bottom Line summary and the notes on individual interaction pages — and any such commentary is noted as ours.

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, which raises the chance of a dangerous rhythm. Some of the worst offenders are ordinary items, including alcoholic drinks and large amounts of grapefruit.

There are no minor-rated entries on this page at all, just 41 moderates behind those nine majors, so nothing here is trivial. Siberian cocklebur stands out because it has been tied to actual cases of liver failure. Most of these problems show up on blood tests and heart tracings before you would feel a thing, so give your oncology team a complete list of everything you take before your next infusion.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. 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
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
  • Each entry links to a full report with the clinical detail, likelihood, evidence level, and citations for that exact combination.
  • Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.

How Does Our Interaction Checker Work?

Behind every verdict on this page is a category system. Our source database doesn’t document supplement interactions drug-by-drug — it documents them against groups of medications that behave the same way (for example, “drugs processed by the CYP3A4 liver enzyme” or “blood-thinning medications”).

So the check works in three steps: (1) Tebentafusp-tebn is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Tebentafusp-tebn, and (3) each ingredient keeps its own severity, likelihood, and evidence grades from the underlying record. That’s why one supplement can carry several records for one drug — it may interact through more than one category.

Tebentafusp-tebn sits in 2 interaction categories. Open any one to see what the group means:

Hepatotoxic Drugs 38 ingredients

Medications with known liver considerations. Supplements that can stress the liver add to the load.

38 of the supplement ingredients on this page reach Tebentafusp-tebn through this category.

Qt Interval-Prolonging Drugs 13 ingredients

Medications that can affect the heart's electrical rhythm (the QT interval). Supplements with similar effects can add to that risk.

13 of the supplement ingredients on this page reach Tebentafusp-tebn through this category.

Tebentafusp-tebn & Supplements: Common Questions

What supplements interact with Tebentafusp-tebn?
Our database currently documents 50 ingredients with a known Tebentafusp-tebn interaction (9 major, 41 moderate, 0 minor). The practical move: scan the major group first, then look up the exact supplements you take rather than reading all 50. The highest-ranked right now: Siberian Cocklebur, Arsenic, Beer.
Which Tebentafusp-tebn supplement interactions are the most serious?
The 9 major-rated combinations — led by Siberian Cocklebur, Arsenic, Beer, Cesium and Ephedra — deserve real caution: these are the ones generally best avoided, or used only with your prescriber watching. If you take any of them today, don't panic and don't stop anything abruptly — call your pharmacist first. Jump to the ranked list.
Can I take vitamins or supplements while on Tebentafusp-tebn?
Plenty of supplements coexist fine with Tebentafusp-tebn; a shorter list does not. Rather than memorizing it, check the specific ingredients on your labels — the ranked list above covers every one we've checked, and multi-ingredient products can be checked label-by-label with our scanner. Try the label scanner or the interaction checker.
Do brands like Kimmtrak have the same supplement interactions as Tebentafusp-tebn?
Yes — Kimmtrak all contain Tebentafusp-tebn, so everything on this page applies to them equally. Interactions belong to the active drug, never to the brand on the box; the same is true of generics.
Where do these interaction ratings come from?
Every rating comes from the Natural Medicines database — the same evidence-graded reference pharmacists and hospitals use — and each interaction carries three separate grades: severity (how bad it can be), likelihood (how well it's documented in studies and case reports), and an evidence level. Our pharmacists review the content; we never let an AI decide an interaction. See how to read the ratings and our editorial policy.
What about Tebentafusp-tebn and my other medications?
