The bottom line No known interaction

We found no known interaction between Cnidium 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.

Cnidium 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 Cnidium 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 Pemigatinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pemigatinib is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Cnidium has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and cns depressants (moderate) — and none of Pemigatinib’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 Pemigatinib’s Own FDA Label Lists

This is not an interaction — none of it involves Cnidium. These are the most notable effects listed in the ADVERSE REACTIONS section of Pemigatinib’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • A bowel blockage Worth acting on
  • Dehydration Worth acting on
  • Low sodium Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on

Showing the 10 most notable of 40 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Pemigatinib. Read the label on DailyMed › Where a percentage is shown, it is the share of 788 voluntary FDA FAERS reports for Pemigatinib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Cnidium’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cnidium side to compare — that is a limit of the record, not a statement that Cnidium has no side effects.

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.”

About Cnidium

What is Cnidium?

Cnidium
  • Skin conditions and itching
  • Erectile dysfunction and low libido
  • Eczema and dermatitis
  • Antifungal or antimicrobial washes
  • Athletic performance
  • General antioxidant support

Cnidium is the dried fruit of an Asian plant long used in traditional Chinese medicine, mostly for skin problems and sexual health. Modern human evidence for these uses is very limited, with most research coming from laboratory and animal studies. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Cnidium monnieri · Apiaceae (Umbelliferae) · Dried ripe fruit (seeds); sometimes the rhizome · Capsules, powdered extract, tinctures, topical creams and ointments, and as an ingredient in traditional Chinese herbal formulas

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

Cnidium: dosing

There is no well-established, standardized dose for Cnidium. Traditional formulas and modern products vary widely in strength and form.If you choose to use a Cnidium product, follow the directions on the label and do not exceed the recommended amount.

About Pemigatinib

What Is Pemigatinib Used For?

Brand name: Pemazyre

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.

Disease progression 140 reports
