Drug & supplement interaction

Evodia + Trastuzumab-Anns

Trastuzumab-Anns brand name: Kanjinti.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Evodia and Trastuzumab-Anns in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Evodia and Trastuzumab-Anns

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 Trastuzumab-Anns and Evodia 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.

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 to actually watch for

No Interaction Found — But Data Suggests Evodia and Trastuzumab-Anns May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

Effects for Trastuzumab-Anns come from the ADVERSE REACTIONS section of its FDA label; effects for Evodia come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,490 voluntary FDA FAERS reports for Trastuzumab-Anns that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About Evodia

What is Evodia?

  • Digestive upset and nausea
  • Headaches
  • Menstrual cramps
  • Abdominal pain
  • Diarrhea

Evodia is a fruit used in traditional Chinese medicine, most often for digestive complaints, headaches, and menstrual pain. Human evidence for these uses is very limited, and it is mostly studied in laboratory and animal research. Talk with a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Tetradium ruticarpum · Rutaceae · Dried unripe fruit · Dried fruit, powder, capsules, tablets, teas, and traditional herbal formulas

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

Evodia: dosing

There is no well-established standard dose for evodia. Traditional use often relies on combination formulas prepared by trained practitioners, and modern supplement products vary widely in strength and ingredients.If you choose to use evodia, follow the directions on the product label and do not exceed the recommended amount.

Taking Evodia and Trastuzumab-Anns Together: Common Questions

Is it safe to take Evodia with Trastuzumab-Anns?
We do not list a known interaction between Evodia and Trastuzumab-Anns. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Evodia and Trastuzumab-Anns have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Evodia interact with any other medications?
Yes. Evodia has 950 documented drug interactions in our database — Trastuzumab-Anns is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
