Pao Pereira and Bendamustine

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 Bendamustine and Pao Pereira 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 Pao Pereira at all — not against Bendamustine, 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.

Overlapping uses

What Bendamustine Is Prescribed For, and What Pao Pereira Has Been Studied For

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

Bendamustine is prescribed for: Bendamustine hydrochloride injection is used to treat adults with chronic lymphocytic leukemia (CLL). It is also used for adults with indolent B-cell non-Hodgkin lymphoma (NHL) — a slow-growing type of blood cancer — when the disease has continued to progress during or within six months of treatment with rituximab or a rituximab-containing regimen. For CLL, how well bendamustine works compared to other first-line treatments (aside from chlorambucil) has not been fully established.

Pao Pereira has been studied for:

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

    Pao Pereira for cancer

    Although there has been interest in using oral pao pereira for cancer, there is insufficient reliable information about the clinical effects of pao pereira for this purpose.

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

From our pharmacist’s overview on the Bendamustine page

“Bendamustine (Treanda, Belrapzo, Vivimusta) is IV chemotherapy for chronic lymphocytic leukemia and certain lymphomas, and the liver clears it through an enzyme called CYP1A2. That enzyme is why nearly all 87 supplements on this page appear here, since about 80 of them can push CYP1A2 up or down, which could either raise side effects o…”

About Pao Pereira

What is Pao Pereira?

  • Immune support
  • Cancer support (complementary use)
  • Antimalarial/fever (traditional)
  • Digestive complaints (traditional)
  • General tonic

Pao Pereira is a bark extract from a South American tree that is marketed mainly as a complementary cancer and immune-support supplement. Human evidence is very limited, and most research comes from laboratory and animal studies, so it should not be used in place of proven medical care. Talk with your pharmacist or doctor before trying it, especially if you have a serious health condition.

Geissospermum laeve · Apocynaceae · Bark (and bark extract) · Capsules, tinctures, liquid extracts, powdered bark

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

Pao Pereira: dosing

There is no established or standardized dose for Pao Pereira. Different products contain different amounts and strengths of bark extract.If you choose to use it, follow the directions on the product label and do not exceed the recommended amount.
