The bottom line No known interaction

We found no known interaction between Phlorizin and Sucralfate 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. Additionally, although there is no interaction, the label for Sucralfate states a food rule worth keeping to.

Phlorizin and Sucralfate

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 Sucralfate 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.

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

How we checked

Why No Interaction Is Listed for Sucralfate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sucralfate is filed under a single classification — oral drugs. Phlorizin has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Sucralfate’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 Sucralfate’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 Sucralfate’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on
  • Shortness of breath Worth acting on
  • Hives Worth acting on
  • An allergic reaction Worth acting on
  • Bloating or gas
  • Dry mouth
  • Back pain
  • Drowsiness
  • Trouble sleeping
  • Stomach upset

From the ADVERSE REACTIONS section of the FDA label for Sucralfate. Read the label on DailyMed › 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.

How to take them

Some Sucralfate Products Have a Food Rule — Phlorizin Should Not Break It

At least one FDA label for a product containing Sucralfate says to take it on an empty stomach. Most supplements — Phlorizin included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Sucralfate on its own and move Phlorizin to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Sucralfate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

D O S A G E A N D A D M INI S T R A T I O N A cti v e D u oden a l Ulc e r : The recommended adult oral dosage for duodenal ulcer is 1 g four times per day on an empty stomach.

From the Dosage and Administration section of the FDA label we read for Sucralfate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Everything else you take

See Every Supplement That Interacts With Sucralfate

This page covers Phlorizin only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sucralfate page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Sucralfate page

“If you take sucralfate (Carafate) to heal an ulcer, keep activated charcoal well away from it. Charcoal carries the sole major rating on this list because it adsorbs drugs in the digestive tract, and sucralfate works entirely there, forming a protective coating over damaged stomach lining rather than circulating through the body.”

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.

Taking Phlorizin and Sucralfate Together: Common Questions

Is it safe to take Phlorizin with Sucralfate?
We do not list a known interaction between Phlorizin and Sucralfate. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Phlorizin and Sucralfate at the same time of day?
At least one FDA label for a product containing Sucralfate says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Sucralfate on its own and move Phlorizin to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Phlorizin and Sucralfate combination checked?
Interactions in our licensed database are recorded against drug classes. Sucralfate is filed under 1 classification, and Phlorizin has documented interactions with 1 drug class — none of Sucralfate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Phlorizin interact with any other medications?
Yes. Phlorizin has 86 documented drug interactions in our database — Sucralfate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Sucralfate interact with any supplements?
Yes. Sucralfate has documented interactions with 17 supplements in our database — Phlorizin is not one of them. The Sucralfate interaction page linked on this page lists every one, ranked by severity.
