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 Ellagic Acid and Thiotepa 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.

Ellagic Acid and Thiotepa

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 Thiotepa and Ellagic Acid 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.

Ellagic Acid safety at a glance

Ellagic Acid overall Use caution Generally considered safe in foods, but concentrated supplements are not well studied in humans.
Pregnancy Avoid Not enough safety data on supplement doses; food amounts are fine but avoid concentrated supplements.
Breastfeeding Avoid There is not enough safety information, so concentrated supplements are best avoided.

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

How we checked

Why No Interaction Is Listed for Thiotepa

Interactions in our licensed database are recorded against drug classes, not just single drug names. Thiotepa is filed under 5 classifications — including alkylating agents, antineoplastics, cytochrome p450 2b6 (cyp2b6) substrates. Ellagic Acid has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Thiotepa’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 Ellagic Acid and Thiotepa 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.

  • Diarrhea / Nausea Additional detail

    Ellagic Acid

    “Orally, a combination of ellagic acid and graviola was associated with nausea and diarrhea in 2 out of 30 patients in one clinical trial, leading to discontinuation. It is unclear if these effects are due to ellagic acid, graviola, or the combination.”

Overlapping uses

What Thiotepa Is Prescribed For, and What Ellagic Acid Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Thiotepa is a prescription medicine with approved uses on its FDA label. Ellagic Acid is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Thiotepa is prescribed for: Tepadina (thiotepa) injection is used for several purposes. It treats adenocarcinoma (a type of cancer) of the breast or ovary. It is also used to control malignant effusions — abnormal fluid buildup in body cavities caused by cancer spreading to those areas. For bladder cancer, Tepadina treats superficial papillary carcinoma of the urinary bladder.

Read the rest of what Thiotepa is prescribed for

Tepadina is also used in pediatric patients with class 3 beta-thalassemia (a severe inherited blood disorder). In those patients, it is given as part of a preparative regimen — a conditioning treatment to reduce the risk of graft rejection before an allogeneic stem cell transplant (a transplant using donor stem cells), alongside the chemotherapy drugs busulfan and cyclophosphamide.

Ellagic Acid has been studied for:

  • Bladder cancer studied, not established Ellagic Acid has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Ellagic Acid for bladder cancer

    Low-quality, observational research in adults with intermediate- to high-risk non-muscular invasive bladder cancer has found that taking ellagic acid 100 mg and graviola 100 mg daily for 6 months following an induction cycle is associated with 83% higher recurrence-free survival when compared with no intervention.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Thiotepa on your own; if you are taking Ellagic Acid for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Thiotepa

This page covers Ellagic Acid only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Thiotepa page lists 146 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Acerola (moderate).

By severity: 3 major · 102 moderate · 41 minor.

From our pharmacist’s overview on the Thiotepa page

“Thiotepa (Thioplex, Tepadina) is chemotherapy, given for several cancers and to prepare patients for stem cell transplant, so its 146 supplement interactions make up a list to respect rather than skim. Three carry a major rating: grapefruit, St.”

About Ellagic Acid

What is Ellagic Acid?

  • Antioxidant support
  • General anti-aging or 'cleanse' products
  • Cancer prevention interest
  • Skin and beauty products
  • Heart and metabolic health

Ellagic acid is a natural plant compound (a polyphenol) found in foods like pomegranates, raspberries, strawberries, and walnuts. It is studied mostly in laboratory and animal research for antioxidant and possible anti-cancer effects, but strong human evidence is lacking. Eating ellagic-acid-rich foods is healthy, but supplements are not proven to treat any disease, so check with a pharmacist or doctor before using them.

Naturally found in the fruit, seeds, and skins of many plants · Capsules, tablets, powders, and as part of fruit extracts (such as pomegranate or red raspberry seed extract)

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

Ellagic Acid: dosing

There is no well-established standard dose of ellagic acid as a supplement. Research studies have used different amounts and different forms, so it is hard to recommend a specific milligram amount.If you choose to use a product, follow the directions on the label and do not exceed the recommended dose.

Taking Ellagic Acid and Thiotepa Together: Common Questions

Is it safe to take Ellagic Acid with Thiotepa?
We do not list a known interaction between Ellagic Acid and Thiotepa. 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 Ellagic Acid and Thiotepa have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Are Ellagic Acid and Thiotepa used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Ellagic Acid in each. That is a conversation for your prescriber, especially if Thiotepa is being adjusted to a target.
How was the Ellagic Acid and Thiotepa combination checked?
Interactions in our licensed database are recorded against drug classes. Thiotepa is filed under 5 classifications, and Ellagic Acid has documented interactions with 1 drug class — none of Thiotepa's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Ellagic Acid interact with any other medications?
Yes. Ellagic Acid has 86 documented drug interactions in our database — Thiotepa is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Thiotepa interact with any supplements?
Yes. Thiotepa has documented interactions with 146 supplements in our database — Ellagic Acid is not one of them. The Thiotepa interaction page linked on this page lists every one, ranked by severity.
