Combretum Micranthum + Amivantamab-Vmjw

Amivantamab-Vmjw brand name: Rybrevant.

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 Combretum Micranthum and Amivantamab-Vmjw 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.

Interaction report

Combretum Micranthum and Amivantamab-Vmjw

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 Amivantamab-Vmjw and Combretum Micranthum 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

No Interaction Found — But Data Suggests Combretum Micranthum and Amivantamab-Vmjw 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.

About Combretum Micranthum

What is Combretum Micranthum?

Combretum Micranthum
  • Digestive upset
  • Liver and gallbladder support
  • Fever
  • Weight management
  • Mild urinary or fluid retention
  • Traditional opium withdrawal aid

Combretum micranthum (kinkeliba) is a West African shrub whose leaves are brewed into a traditional tea for digestion, liver complaints, and fever. Solid human studies are lacking, so its benefits remain unproven, and people who are pregnant, breastfeeding, or have liver or kidney problems should be cautious and talk to a healthcare professional first.

Combretum micranthum · Combretaceae · Leaves (mainly), and sometimes stems and roots · Tea (herbal infusion or decoction), dried leaf powder, capsules, liquid extracts

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

Combretum Micranthum: dosing

There is no established standardized dose for Combretum micranthum. Traditionally, a handful of dried leaves is steeped in hot water to make a tea, but the strength varies widely from one preparation to another.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.

About Amivantamab-vmjw Injection

What Is Amivantamab-vmjw Injection Used For?

Brand name: Rybrevant

Rybrevant (amivantamab-vmjw) is used to treat adults with locally advanced or metastatic non-small cell lung cancer (NSCLC) that carries specific changes (mutations) in the EGFR gene. The exact regimen depends on which mutation is present and whether prior treatment has been received.

Rybrevant is used: in combination with lazertinib as a first-line treatment for NSCLC with EGFR exon 19 deletions or exon 21 L858R mutations; in combination with carboplatin and pemetrexed for those same mutations when the cancer progressed after an EGFR tyrosine kinase inhibitor; in combination with carboplatin and pemetrexed as a first-line treatment for NSCLC with EGFR exon 20 insertion mutations; and as a single agent for NSCLC with exon 20 insertion mutations when the cancer progressed after platinum-based chemotherapy. In every case, patients must first be confirmed to carry the relevant mutation by an FDA-approved test.
