Calumba and Netupitant, Palonosetron (Oral)

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 Netupitant, Palonosetron (Oral) and Calumba 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.

What to actually watch for

What Calumba Itself Has Been Linked To

This is not an interaction — nothing below involves Netupitant, Palonosetron (Oral). It is the side-effect record for Calumba on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Calumba, this list is the first place to look.

  • Vomiting Additional detail

    “Orally, large doses of calumba may cause vomiting and epigastric pain (18).”

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

From our pharmacist’s overview on the Netupitant, Palonosetron (Oral) page

“Getting Akynzeo (netupitant and palonosetron) to work is the difference between finishing a chemotherapy cycle comfortably and losing days to nausea, so this list warrants genuine care. Most of it involves a liver enzyme, CYP3A4, that clears netupitant.”

About Calumba

What is Calumba?

  • Poor appetite
  • Digestive upset and indigestion
  • Nausea
  • Diarrhea
  • As a bitter tonic

Calumba is the dried root of an African climbing plant that has long been used as a bitter tonic to stimulate appetite and ease digestive complaints. Modern scientific evidence for these uses is very limited, and its safety has not been well studied, so it should be used cautiously and avoided during pregnancy and breastfeeding.

Jateorhiza palmata · Menispermaceae · Dried root · Dried root, powder, tincture, liquid extract, capsules

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

Calumba: dosing

There is no well-established standardized dose for Calumba. Traditional sources used the dried root, powder, tinctures, or liquid extracts, but reliable modern dosing guidelines do not exist.If you choose to use a Calumba product, follow the directions on the label and do not exceed them.

About Netupitant and Palonosetron

What Is Netupitant and Palonosetron Used For?

Brand name: Akynzeo

Akynzeo capsules are used in adults to prevent both the short-term (acute) and longer-lasting (delayed) nausea and vomiting that can follow cancer chemotherapy — including, but not limited to, highly emetogenic (strongly nausea-causing) chemotherapy regimens. It is always taken together with the steroid dexamethasone.

Akynzeo capsules cover a broad range of chemotherapy regimens, including anthracycline plus cyclophosphamide-based regimens. Each ingredient targets a different stage: palonosetron addresses nausea and vomiting in the first 24 hours, while netupitant covers both the early and the delayed phase that can last several days after treatment.
