Drug & supplement interaction

Javanese Turmeric + Fosaprepitant

Fosaprepitant brand names: Emend Injection, Focinvez.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Javanese Turmeric and Fosaprepitant 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.

Interaction report

Javanese Turmeric and Fosaprepitant

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 Fosaprepitant and Javanese Turmeric 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.

Javanese Turmeric safety at a glance

Javanese Turmeric overall Use caution Generally well tolerated in food-like amounts, but human safety data for concentrated supplements are limited.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoiding it is the safer choice.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Fosaprepitant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fosaprepitant is filed under 4 classifications — including cytochrome p450 2c9 (cyp2c9) inducers, cytochrome p450 3a4 (cyp3a4) inducers, cytochrome p450 3a4 (cyp3a4) inhibitors. Javanese Turmeric has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Fosaprepitant’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Javanese Turmeric and Fosaprepitant May Share Several of the Same Side Effects

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.

From our pharmacist’s overview on the Fosaprepitant page

“Fosaprepitant (Emend Injection, Focinvez) is the IV drug that keeps chemotherapy from making you sick, so anything that undercuts it costs you real comfort, and I would treat this list with genuine care before adding a supplement to it. Nearly all 141 entries hinge on one liver enzyme, CYP3A4, and the traffic runs both ways, since some…”

About Javanese Turmeric

What is Javanese Turmeric?

  • Digestive upset and bloating
  • Liver and gallbladder support
  • Loss of appetite
  • Joint and inflammation complaints
  • General wellness tonic

Javanese turmeric (Curcuma zanthorrhiza), known in Indonesia as temulawak, is a ginger-family root traditionally used for digestive and liver complaints. Early lab and animal studies are interesting, but strong human evidence is limited, so it should be viewed as a traditional remedy rather than a proven treatment. Talk to a pharmacist or doctor before using it, especially if you have a health condition or take medications.

Curcuma zanthorrhiza · Zingiberaceae · Rhizome (root) · Capsules, tablets, powder, dried root, tea, liquid extracts

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

Javanese Turmeric: dosing

There is no well-established standardized dose for Javanese turmeric. Products vary widely in strength and form, and the active compounds are absorbed differently from one preparation to another.The safest approach is to follow the directions on the product label and not exceed the recommended amount.
