Bugle 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 Bugle 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 Bugle 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.

What Larotrectinib’s Own FDA Label Lists

This is not an interaction — none of it involves Bugle. These are the most notable effects listed in the ADVERSE REACTIONS section of Larotrectinib’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Memory problems Worth acting on
  • Hallucinations Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Chest pain Worth acting on
  • Low mood Worth acting on
  • Anemia Worth acting on
  • Shortness of breath Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Larotrectinib. Read the label on DailyMed › Bugle’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Bugle side to compare — that is a limit of the record, not a statement that Bugle has no side effects.

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…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Bugle is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Bugle reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Bugle and Larotrectinib records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Bugle

What is Bugle?

  • Minor wounds and bruises
  • Sore throat and mouth irritation
  • Mild cough
  • Digestive complaints
  • Bleeding (traditional use)

Bugle (Ajuga reptans) is a traditional European herb once used to help wounds, bruises, and mouth or throat irritation. There is very little modern scientific research to confirm any of these uses, so its benefits remain unproven. If you want to try it, talk to a pharmacist or doctor first, and avoid it during pregnancy and breastfeeding because safety data are lacking.

Ajuga reptans · Lamiaceae · Aerial parts (leaves and flowering tops) · Dried herb, tea, tincture, topical preparations

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

Bugle: dosing

There is no established or standardized dose for bugle. Traditional use varied, and modern products are not common or well regulated.If you choose to use a bugle product, follow the directions on the label and do not exceed them.

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.
