American Ivy and Ipilimumab

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 Ipilimumab 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.

What to actually watch for

What Ipilimumab’s Own FDA Label Lists

This is not an interaction — none of it involves American Ivy. These are the most notable effects listed in the ADVERSE REACTIONS section of Ipilimumab’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • A change in thyroid levels Worth acting on
  • A bowel blockage Worth acting on
  • Severe muscle breakdown Worth acting on
  • Dehydration Worth acting on
  • Trouble swallowing Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low blood sugar Worth acting on
  • Low potassium Worth acting on

Showing the 10 most notable of 61 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Ipilimumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 42,912 voluntary FDA FAERS reports for Ipilimumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. American Ivy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no American Ivy side to compare — that is a limit of the record, not a statement that American Ivy has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. American Ivy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every American Ivy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The American Ivy and Ipilimumab records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About American Ivy

What is American Ivy?

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 Ipilimumab Injection

What Is Ipilimumab Injection Used For?

Brand name: Yervoy

Yervoy (ipilimumab) is used to treat a range of advanced cancers. As a single agent, Yervoy treats unresectable (cannot be surgically removed) or metastatic melanoma in adults and children 12 and older, and is also used as adjuvant (after-surgery) treatment in adults with melanoma that has spread to nearby lymph nodes. Most of its other uses are in combination with nivolumab.

In combination with nivolumab, Yervoy is indicated for advanced renal cell carcinoma (kidney cancer), MSI-H or dMMR metastatic colorectal cancer (in adults and children 12+), unresectable or metastatic hepatocellular carcinoma (liver cancer), metastatic non-small cell lung cancer, unresectable malignant pleural mesothelioma, and unresectable advanced or metastatic esophageal squamous cell carcinoma. Some of these uses require tumor testing for specific markers (such as PD-L1 expression or MSI-H/dMMR status) before treatment begins.

Most-Reported Side Effects for Ipilimumab

From FAERS, the FDA’s public side-effect reporting system (42,912 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
