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.

The supplement list for tepotinib (Tepmetko), a targeted lung cancer drug, is one I would treat carefully rather than skim. Nearly everything on it touches the same liver enzyme, CYP3A4, that clears tepotinib from the body, so some products can raise its level and its side effects while others quietly lower it and weaken the treatment itself. Grapefruit and St. John's wort are the clearest examples of each direction, and activated charcoal can trap the drug in the gut before it is ever absorbed.

Most of the remaining entries repeat that enzyme story on thinner evidence, lab findings more than human studies, and a smaller cluster of fiber and charcoal-like products can blunt absorption of any oral medicine, so space those well apart from the tepotinib dose. Only three of the 144 ingredients here carry a major rating, with 103 moderate and 38 minor behind them, but none of the rest matters as much as those three.

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) Tepotinib is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Tepotinib, 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.

Tepotinib sits in 3 interaction categories. Open any one to see what the group means:

Cytochrome P450 3A4 (Cyp3A4) Substrates 121 ingredients

A drug-metabolism group: these medications are processed by the named liver enzyme (a cytochrome P450). Supplements that speed this enzyme up or slow it down can lower or raise the medication's levels in your body.

121 of the supplement ingredients on this page reach Tepotinib through this category.

P-Glycoprotein Substrates 37 ingredients

A drug-transport group: these medications are moved in and out of cells by the P-glycoprotein pump. Supplements that affect the pump can change how much of the drug is absorbed or kept in the body.

37 of the supplement ingredients on this page reach Tepotinib through this category.

Oral Drugs 17 ingredients

A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.

17 of the supplement ingredients on this page reach Tepotinib through this category.

Tepotinib & Supplements: Common Questions

What supplements interact with Tepotinib?
In our interaction database, 144 supplement and herbal ingredients have an interaction with Tepotinib on file — 3 rated major, 103 moderate, and 38 minor. That number sounds scarier than it is: severity matters far more than the count, which is why the list on this page is ranked instead of alphabetical. Start at the top. The highest-ranked right now: Grapefruit, Activated Charcoal, St. John's Wort.
Which Tepotinib supplement interactions are the most serious?
The 3 major-rated combinations — led by Grapefruit, Activated Charcoal and St. John's Wort — 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 Tepotinib?
That depends entirely on which supplement. The honest answer for Tepotinib is in the ranked list above — and if what you take is a combination product with a dozen ingredients, don't check them one by one: photograph the label with our scanner and we'll check the whole thing at once. Try the label scanner or the interaction checker.
Do brands like Tepmetko have the same supplement interactions as Tepotinib?
Yes — Tepmetko all contain Tepotinib, 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 Tepotinib and my other medications?
This page covers Tepotinib against supplements and herbal ingredients. Checking Tepotinib against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side. Head to the drug–drug interaction checker, or read the full Tepotinib drug information.
