Goa Powder + Abemaciclib

Abemaciclib brand name: Verzenio.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Goa Powder and Abemaciclib 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Goa Powder and Abemaciclib

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 Abemaciclib and Goa Powder 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 Goa Powder at all — not against Abemaciclib, 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.

No Interaction Found — But Data Suggests Goa Powder and Abemaciclib May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

From our pharmacist’s overview on the Abemaciclib page

“A daily pill for a common form of advanced breast cancer, abemaciclib (Verzenio) only helps when its blood level stays steady, so this list of 138 supplements deserves genuine care. Nearly all of them act on CYP3A4, the liver enzyme that clears abemaciclib, meaning a supplement can push its level up and intensify side effects, or drag…”

About Goa Powder

What is Goa Powder?

  • Psoriasis (topical)
  • Ringworm and other fungal skin infections
  • Scaly skin conditions
  • Eczema-like rashes

Goa powder (also called araroba) is a natural source of chrysarobin, a substance historically used on the skin for psoriasis and fungal infections. It is a harsh, irritating chemical that is mostly of historical interest today, and it should never be swallowed. If you are considering anything containing chrysarobin or anthralin, talk with a doctor or pharmacist first.

Andira araroba · Fabaceae · A yellow powder (chrysarobin) extracted from the wood and trunk cavities of the araroba tree · Topical ointments, pastes, and creams; historically a raw powder

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

Goa Powder: dosing

There is no established or standardized dose for Goa powder as a supplement. Historically it was mixed into ointments at concentrations chosen by a pharmacist or physician, and even then it had to be used carefully because of irritation and staining.If you encounter a product that contains chrysarobin or the related medicine anthralin, follow the product label exactly and do not apply more than directed. Because this is a potent and irritating substance, it is best to use it only under the guidance of a doctor or pharmacist.

About Abemaciclib

What Is Abemaciclib Used For?

Brand name: Verzenio

Verzenio (abemaciclib) is used to treat HR-positive, HER2-negative breast cancer in adults. For early breast cancer at high risk of recurrence, Verzenio is taken alongside endocrine therapy (tamoxifen or an aromatase inhibitor) after surgery to help prevent the cancer from coming back.

For advanced or metastatic breast cancer (cancer that has spread), Verzenio can be used in combination with an aromatase inhibitor as a first hormonal treatment, in combination with fulvestrant after the cancer has progressed on endocrine therapy, or alone after prior endocrine therapy and chemotherapy have stopped working.
