No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between American Pawpaw and Encorafenib 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.

American Pawpaw and Encorafenib

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 Encorafenib and American Pawpaw 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.

American Pawpaw safety at a glance

American Pawpaw overall Use caution The ripe fruit is generally eaten as food, but concentrated leaf, twig, and seed extracts may be toxic and lack good safety data.
Pregnancy Avoid There is not enough safety information, and concentrated extracts may be harmful, so avoid during pregnancy.
Breastfeeding Avoid Safety has not been studied, so avoid concentrated pawpaw supplements while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Encorafenib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Encorafenib is filed under 4 classifications — including qt interval-prolonging drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates. American Pawpaw has documented interactions with 1 drug class — the most serious being antineoplastics (minor) — and none of Encorafenib’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.

No Interaction Found — But Data Suggests American Pawpaw and Encorafenib 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 Encorafenib page

“Grapefruit is the first thing I would take off the table for anyone on encorafenib (Braftovi), a targeted cancer medicine, because it blocks the enzyme (CYP3A4) that clears the drug, pushing levels and side effects higher. St.”

About American Pawpaw

What is American Pawpaw?

American Pawpaw
  • Anticancer interest
  • Lice and head lice treatment (topical)
  • Traditional digestive remedy
  • General wellness/antioxidant
  • Insecticide (historical seed use)

American pawpaw is a North American fruit tree whose leaves, twigs, and seeds contain compounds called acetogenins that have shown cancer-cell-killing activity in laboratory studies. However, strong human evidence for any health benefit is lacking, and the seeds, bark, and unripe parts can be toxic, so supplements should be used cautiously and only under professional guidance.

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

American Pawpaw: dosing

There is no established standardized dose for American pawpaw supplements. Products vary widely in strength and which part of the plant they use, which makes safe dosing hard to determine.If you choose to use a pawpaw product, follow the directions on the label and do not exceed them.

About Encorafenib

What Is Encorafenib Used For?

Brand name: Braftovi

Braftovi is used to treat cancers that have a specific change (mutation) in a gene called BRAF — specifically the V600E or V600K mutation, which must be confirmed by an FDA-authorized test before starting treatment. It is always used in combination with other medicines, never alone as standard therapy.

Braftovi (in combination with binimetinib) treats unresectable or metastatic melanoma with a BRAF V600E or V600K mutation. For metastatic colorectal cancer (mCRC) with a BRAF V600E mutation, Braftovi is used either with cetuximab and fluorouracil-based chemotherapy, or with cetuximab alone after prior therapy. Braftovi (in combination with binimetinib) also treats metastatic non-small cell lung cancer (NSCLC) with a BRAF V600E mutation.

Most-Reported Side Effects for Encorafenib

From FAERS, the FDA’s public side-effect reporting system (9,844 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 842 reports
Fatigue 770 reports
Diarrhea 634 reports

Do American Pawpaw and Encorafenib have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the American Pawpaw and Encorafenib combination checked?
Interactions in our licensed database are recorded against drug classes. Encorafenib is filed under 4 classifications, and American Pawpaw has documented interactions with 1 drug class — none of Encorafenib'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.
