The bottom line No known interaction

We found no known interaction between Codonopsis and Pacritinib 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.

Codonopsis and Pacritinib

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 Pacritinib and Codonopsis 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.

Codonopsis safety at a glance

Codonopsis overall Use caution Generally considered well tolerated in traditional food-like amounts, but high-quality safety data are limited.
Pregnancy Avoid Not enough reliable safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid it unless your doctor advises otherwise.

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

How we checked

Why No Interaction Is Listed for Pacritinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pacritinib is filed under 5 classifications — including cytochrome p450 1a2 (cyp1a2) inhibitors, qt interval-prolonging drugs, cytochrome p450 3a4 (cyp3a4) inhibitors. Codonopsis has documented interactions with 3 drug classes — the most serious being abiraterone (zytiga) (moderate), anticoagulant/antiplatelet drugs (moderate) and antidiabetes drugs (moderate) — and none of Pacritinib’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

What Codonopsis Itself Has Been Linked To

This is not an interaction — nothing below involves Pacritinib. It is the side-effect record for Codonopsis on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Codonopsis, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

  • Unsteadiness / Confusion Worth acting on Additional detail

    “Orally, very large doses of codonopsis (30-60 grams) may cause vision problems, dizziness, loss of balance, leg spasms, and confusion (12).”

    “Orally, codonopsis can cause allergic reactions including anaphylaxis and urticaria. In one case report, an 18-year-old male developed anaphylaxis after ingesting codonopsis roots. In an oral re-challenge test, he developed anaphylaxis and urticaria again 30 minutes after consuming 20 grams of codonopsis root.”

Everything above comes from the Natural Medicines adverse-effect record for Codonopsis — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Pacritinib’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Pacritinib column appears here.

Overlapping uses

What Pacritinib Is Prescribed For, and What Codonopsis Has Been Studied For

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

Pacritinib is prescribed for: Vonjo (pacritinib) is used to treat adults with intermediate or high-risk myelofibrosis (MF) — a serious bone marrow disease — including primary MF and secondary MF that developed after polycythemia vera or essential thrombocythemia (other blood disorders). It is specifically approved for patients whose platelet count is below 50 × 10⁹/L (very low platelets), a group that has limited treatment options. This approval is based on demonstrated reductions in spleen size. Continued approval may depend on results from confirmatory trials showing broader clinical benefit.

Codonopsis has been studied for:

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

    Codonopsis for cancer

    Although there is interest in using oral Codonopsis lanceolata for cancer, there is insufficient reliable information about the clinical effects of codonopsis for this condition.

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 Pacritinib on your own; if you are taking Codonopsis for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Pacritinib

This page covers Codonopsis only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pacritinib page lists 158 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Cesium (major) and Ephedra (major).

By severity: 8 major · 110 moderate · 40 minor.

From our pharmacist’s overview on the Pacritinib page

“Someone on pacritinib (Vonjo) is usually fighting myelofibrosis, and the supplements people reach for during cancer treatment, herbal blends, immune boosters, St. John's wort for mood, are where this list gets serious.”

About Codonopsis

What is Codonopsis?

  • Fatigue and low energy
  • Digestive support and poor appetite
  • Immune support
  • General tonic ('qi' tonic in Traditional Chinese Medicine)
  • Cough and weakness during recovery from illness

Codonopsis (often called 'dang shen') is a root long used in Traditional Chinese Medicine as a gentle energy and digestive tonic, frequently as a milder substitute for ginseng. Human research is very limited, so its benefits are not well proven. It appears reasonably well tolerated in food-like amounts, but you should talk with a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a health condition.

Codonopsis pilosula · Campanulaceae · Dried root · Dried root, slices, decoctions (teas/soups), powders, capsules, tinctures, and herbal formulas

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

Codonopsis: dosing

There is no official, standardized dose of Codonopsis. Traditional preparations often use the dried root in soups or decoctions, while commercial products come as capsules, powders, and tinctures in widely varying strengths.Follow the directions on your specific product label, and do not assume more is better. A pharmacist or doctor can help you decide whether it is appropriate for you and what amount may be reasonable.

Taking Codonopsis and Pacritinib Together: Common Questions

Is it safe to take Codonopsis with Pacritinib?
We do not list a known interaction between Codonopsis and Pacritinib. 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.
Are Codonopsis and Pacritinib 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 Codonopsis in each. That is a conversation for your prescriber, especially if Pacritinib is being adjusted to a target.
How was the Codonopsis and Pacritinib combination checked?
Interactions in our licensed database are recorded against drug classes. Pacritinib is filed under 5 classifications, and Codonopsis has documented interactions with 3 drug classes — none of Pacritinib'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 Codonopsis interact with any other medications?
Yes. Codonopsis has 211 documented drug interactions in our database — Pacritinib 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 Pacritinib interact with any supplements?
Yes. Pacritinib has documented interactions with 158 supplements in our database — Codonopsis is not one of them. The Pacritinib interaction page linked on this page lists every one, ranked by severity.
