The bottom line No known interaction

We found no known interaction between Phlorizin 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.

Phlorizin 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 Phlorizin 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.

Phlorizin overall Not established Human safety data for phlorizin supplements are very limited.

Breastfeeding Avoid No safety information exists for nursing, so avoid use.

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. Phlorizin has documented interactions with 1 drug class — the most serious being antidiabetes drugs (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 Phlorizin. 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. Phlorizin’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Phlorizin side to compare — that is a limit of the record, not a statement that Phlorizin 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.”

About Phlorizin

What is Phlorizin?

  • Blood sugar support
  • Diabetes research
  • Antioxidant
  • Weight management interest

Phlorizin is a natural plant compound (a dihydrochalcone) found in apple tree bark and other plants that has been studied mostly in the laboratory for its effects on blood sugar handling. There is no good human evidence that taking it as a supplement is safe or effective, and it is poorly absorbed when swallowed. Talk with your pharmacist or doctor before using any product containing it.

Root bark, bark, and leaves of apple trees and related Rosaceae plants · Purified compound (research chemical), capsules, powders

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

Phlorizin: dosing

There is no established or standardized dose of phlorizin for supplement use in humans. It has mainly been used in research settings at carefully controlled amounts, not as a routine oral supplement.If you choose to use a product that contains phlorizin or apple bark extract, follow the directions on the product label and do not exceed the recommended amount.

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.
