American Ivy and Ravulizumab-Cwvz

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 Ravulizumab-Cwvz 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.

Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.

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 October 4, 2026. The American Ivy and Ravulizumab-Cwvz 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 Ravulizumab-cwvz Injection

What Is Ravulizumab-cwvz Injection Used For?

Brand name: Ultomiris

  • Ravulizumab-cwvz injection is used in adults and children 1 month of age and older to treat paroxysmal nocturnal hemoglobinuria (PNH: a type of anemia in which too many red blood cells are broken down in the body, so there are not enough healthy cells to bring oxygen to all parts of the body). Ravulizumab-cwvz injection is also used in adults and children 1 month of age and older to treat atypical hemolytic uremic syndrome (aHUS; an inherited condition in which small blood clots form in the body and may cause damage to the blood vessels, blood cells, kidneys, and other parts of the body). Ravulizumab-cwvz injection is also used in adults to treat a certain form of myasthenia gravis (MG; a disorder of the nervous system that causes muscle weakness). Ravulizumab-cwvz is in a class of medications called monoclonal antibodies. It works by blocking the activity of the part of the immune system that may damage blood cells in people with PNH and that causes clots to form in people with aHUS. It works by disrupting communication between nerves and muscles in people with MG.
