Black Rice + Pemigatinib
Pemigatinib brand name: Pemazyre.
We found no known interaction between Black Rice and Pemigatinib 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.
Black Rice and Pemigatinib
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 Pemigatinib and Black Rice 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Black Rice at all — not against Pemigatinib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.

From our pharmacist’s overview on the Pemigatinib page
“Pemigatinib (Pemazyre) is a targeted therapy for bile duct cancer, and it only works if its blood level stays where it should. Of the 138 supplements and herbs on file, 121 affect the liver enzyme (CYP3A4) that clears pemigatinib, which can push levels up toward worse side effects or pull them down until the cancer goes undertreated.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Black Rice is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Black Rice reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Black Rice and Pemigatinib records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Black Rice
What is Black Rice?
- Heart health support
- Antioxidant intake
- Digestive and gut health
- Blood sugar and weight management
- General nutrition
Black rice is a nutritious whole-grain food that is rich in fiber, plant protein, and antioxidant pigments called anthocyanins. Eaten as part of a balanced diet it is a healthy choice, but strong human evidence that black rice or its extracts treat or prevent specific diseases is still limited. Talk with your pharmacist or doctor before using concentrated black rice supplements.

An interaction check asks whether these two react with each other — it does not ask whether Black Rice is a good idea for someone in your situation. Here is what our Black Rice record says about it on its own.
Black Rice: dosing
There is no established medicinal dose for black rice. As a food, a typical serving is a cooked portion similar to other rice, included as part of a balanced diet.For supplements or extracts, follow the directions on the product label, since amounts vary by product and have not been standardized.

About Pemigatinib
What Is Pemigatinib Used For?

Pemazyre (pemigatinib) is used to treat adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma (bile duct cancer) whose tumors have a specific genetic change called an FGFR2 fusion or rearrangement, confirmed by an FDA-approved test. This approval is based on tumor response rates; continued approval may depend on results from further confirmatory studies.
Pemazyre is also approved to treat adults with relapsed or refractory myeloid/lymphoid neoplasms (MLNs) — certain blood and bone marrow cancers — that carry an FGFR1 rearrangement and have come back or stopped responding to prior treatment.
Most-Reported Side Effects for Pemigatinib
From FAERS, the FDA’s public side-effect reporting system (821 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
