Black Hoof Mushroom 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 Black Hoof Mushroom 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.

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. Black Hoof Mushroom has documented interactions with 3 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate), cytochrome p450 2e1 (cyp2e1) substrates (moderate) and immunosuppressants (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.

From the ADVERSE REACTIONS section of the FDA label for Thiotepa.

About Black Hoof Mushroom

What is Black Hoof Mushroom?

Black Hoof Mushroom
  • Immune system support
  • Antioxidant support
  • General wellness
  • Traditional cancer-supportive use
  • Inflammation

Black Hoof Mushroom (Phellinus linteus) is a medicinal mushroom long used in East Asian traditional medicine, mainly for immune support. Most of the supporting evidence comes from laboratory and animal studies, and high-quality human research is limited. Talk to your pharmacist or doctor before using it, especially if you have a health condition or take other medicines.

Phellinus linteus · Hymenochaetaceae · Fruiting body (the woody mushroom that grows on tree trunks) · Capsules, tablets, powdered extracts, teas, and tinctures

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

Black Hoof Mushroom: dosing

There is no well-established standard dose for Black Hoof Mushroom.

Because formulations differ so much, it is a good idea to review the specific product with your pharmacist or doctor before starting.

What Is Thiotepa Injection Used For?

Brand names: Thioplex, Tepadina

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.

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.
