Ginger and Larotrectinib

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Larotrectinib

Larotrectinib falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Ginger interacts with.

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

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.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: your body uses an enzyme called CYP3A4 to break down larotrectinib (Vitrakvi), and ginger may nudge that enzyme either up or down. If ginger slows CYP3A4 down, larotrectinib could build up and you might notice more of its usual side effects, like dizziness, tiredness, nausea, or numbness and tingling in the hands and feet. If ginger speeds the enzyme up instead, your levels could drop and the drug may not fight your cancer as well.

Honestly, this is mostly lab-based evidence with only a few unclear case reports involving other cancer drugs, not larotrectinib itself. Cooking with ginger is unlikely to matter much, but concentrated supplements are worth a quick chat with your oncology pharmacist or doctor before starting.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction 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.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

“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…”

  • Menstrual cramps
  • Joint pain and inflammation

Ginger is a widely used culinary spice with a long history in traditional medicine, and it has the strongest evidence for helping with nausea and vomiting, including from motion sickness, pregnancy, and chemotherapy. It is generally safe in food and supplement amounts for most people, though it may cause mild stomach upset. Talk with your pharmacist or doctor before using ginger supplements, especially if you are pregnant, have a bleeding disorder, or take other medicines.

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 — without a known acquired resistance mutation. It is used when the tumor has spread (is metastatic) or when surgery would likely cause severe harm, and when there are no satisfactory alternative treatments or the cancer has continued to grow after prior treatment.

Patients are selected for Vitrakvi based on an FDA-approved test that confirms the NTRK gene fusion in tumor tissue. This approval was granted under the FDA's accelerated approval pathway, based on overall response rate and duration of response; continued approval may depend on results from confirmatory trials.
