Burning Bush and Larotrectinib

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 Larotrectinib and Burning Bush 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Burning Bush at all — not against Larotrectinib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

From our pharmacist’s overview on the Larotrectinib page

“Nearly everything on this page interacts with larotrectinib (Vitrakvi) in one of two directions, raising or lowering how much of the drug ends up in your blood. Larotrectinib treats cancers driven by an NTRK gene fusion, and it is cleared by a liver enzyme called CYP3A4, so herbs that speed that enzyme up can drain the drug's effect wh…”

About Burning Bush

What is Burning Bush?

  • Constipation
  • Liver and gallbladder complaints
  • Fluid retention
  • Skin conditions
  • Traditional 'blood cleansing'

Burning Bush (Euonymus atropurpureus), also called wahoo, is a traditional North American remedy historically used as a laxative and 'liver tonic.' There is very little modern scientific evidence to support these uses, and the plant contains compounds that can be toxic, so it is generally not recommended for self-treatment.

Euonymus atropurpureus · Celastraceae · Bark (root bark and stem bark) · Dried bark, powder, tincture, capsules, tea

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

Burning Bush: dosing

There is no established, standardized safe dose for Burning Bush. It is not a well-studied modern supplement, and the strength of bark products can vary widely.Because of the risk of toxicity, we do not provide specific amounts. For common problems like constipation, there are safer and better-studied options available.

About Larotrectinib

What Is Larotrectinib Used For?

Brand name: Vitrakvi

Vitrakvi is used to treat adult and pediatric patients with solid tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion — a specific genetic alteration that can drive tumor growth. It is used when the tumor is metastatic (has spread) or when surgery to remove it would likely cause serious harm, and when there are no satisfactory alternative treatments or the cancer has continued to grow after prior treatment.

Patients must be selected for Vitrakvi therapy based on an FDA-approved test that confirms the NTRK gene fusion in their tumor. This approval is under the FDA's accelerated approval pathway, based on how many patients responded to treatment and how long those responses lasted. Continued approval may depend on results from follow-up clinical trials.
