Interaction report

American Ivy 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 American Ivy 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 Ivy safety at a glance

American Ivy overall Use caution Little safety data exists, and the berries are toxic, so use it cautiously and avoid eating any part of the plant.

Pregnancy Avoid There is not enough safety information, so it is best to avoid use during pregnancy.

Breastfeeding Avoid Safety while breastfeeding is unknown, so avoiding it is the safer choice.

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

About American Ivy

What is American Ivy?

Digestive upset
To stimulate sweating
Traditional tonic use
Skin and swelling complaints (topical folk use)

American Ivy (Virginia creeper) is mainly an ornamental climbing vine with a long history of folk use for digestion and sweating, but there is very little human evidence to support any health benefit. Its berries contain oxalic acid and are considered poisonous, and the plant can irritate the skin. Because safety data is limited, talk with your pharmacist or doctor before using it.

Parthenocissus quinquefolia · Vitaceae · Bark, leaves, and stems (berries are considered poisonous) · Dried bark, tinctures, teas; rarely sold as a standardized supplement

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

American Ivy: dosing

There is no established safe or effective dose for American Ivy. It is not a standardized supplement, so the strength of any product can vary a lot.If you choose to use a product that contains it, follow the directions on the label and do not exceed them. Never make a home preparation from the raw plant or its berries.

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 — called mutations — in a gene called EGFR. The particular mutation your tumor has determines which treatment regimen is used.

Rybrevant is approved for use in four situations: as a first-line treatment (with lazertinib) for NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations; in combination with carboplatin and pemetrexed for the same mutations when prior EGFR-targeted therapy has stopped working; 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 EGFR exon 20 insertion mutations after platinum-based chemotherapy has been tried.
