We found no known interaction between American Ivy and Ranitidine 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.

American Ivy and Ranitidine

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 Ranitidine 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.

How we checked

Why No Interaction Is Listed for Ranitidine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ranitidine is filed under 6 classifications — including h2-blockers, cytochrome p450 2d6 (cyp2d6) inhibitors, organic anion transporter 3 (oat3) substrates. American Ivy has documented interactions with 1 drug class — the most serious being thiazide diuretics (moderate) — and none of Ranitidine’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.

What Ranitidine’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 Ranitidine’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.

  • A slow heartbeat Worth acting on
  • Hallucinations Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • An irregular heartbeat Worth acting on
  • Wheezing Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on

Showing the 10 most notable of 37 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 Ranitidine. Read the label on DailyMed › Where a percentage is shown, it is the share of 230,801 voluntary FDA FAERS reports for Ranitidine 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.

From our pharmacist’s overview on the Ranitidine page

“Ranitidine (Zantac) is a heartburn and ulcer medicine gentle enough to have sold over the counter, but two of the 74 supplements and herbs on file with it earn real caution and are worth understanding first. Activated charcoal can soak up ranitidine in the gut and blunt the dose, and St.”

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 Ranitidine 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 Ranitidine

What Is Ranitidine Used For?

Brand names: Zantac 150 EFFER, Zantac 150 GEL, Zantac 150, Zantac Geldose, Zantac, Ranit, Zantac Efferdose, Zantac 300, Zantac 300 GEL, Ranitidine injection

Ranitidine treats a range of stomach acid–related conditions. Prescription-strength ranitidine (capsules, tablets, and oral solution) is used for active duodenal ulcers (ulcers in the small intestine), active benign gastric ulcers (stomach ulcers), GERD (acid reflux disease), erosive esophagitis (acid damage to the esophagus), and pathological hypersecretory conditions — rare disorders where the stomach makes far too much acid, such as Zollinger-Ellison syndrome. It is also used as maintenance therapy to keep duodenal and gastric ulcers from coming back after they have healed.

Over-the-counter products — including Acid Reducer and Acid Reducer 150 tablets — are approved to relieve heartburn associated with acid indigestion and sour stomach, and to prevent that heartburn when taken before eating or drinking foods that trigger it.

Most-Reported Side Effects for Ranitidine

From FAERS, the FDA’s public side-effect reporting system (230,801 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
