Drug & supplement interaction

Greater Celandine + Sucralfate

Sucralfate brand names: Carafate, Antepsin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Greater Celandine 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, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Greater Celandine 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 Greater Celandine 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.

Greater Celandine safety at a glance

Greater Celandine overall Avoid Oral use has been linked to serious, sometimes severe liver damage.
Pregnancy Avoid Not enough safety data and known toxicity make it unsafe during pregnancy.
Breastfeeding Avoid No reliable safety information, so it is best avoided while breastfeeding.

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. Greater Celandine has documented interactions with 4 drug classes — the most serious being cytochrome p450 2d6 (cyp2d6) substrates (moderate), hepatotoxic drugs (moderate) and immunosuppressants (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 to actually watch for

No Interaction Found — But Data Suggests Greater Celandine and Sucralfate May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

    Sucralfate

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

Reported for Greater Celandine but not commonly for Sucralfate: a low platelet count, liver problems, kidney problems and bleeding or bruising.

Effects for Sucralfate come from the ADVERSE REACTIONS section of its FDA label; effects for Greater Celandine come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

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

At least one FDA label for a product containing Sucralfate says to take it on an empty stomach. Most supplements — Greater Celandine 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 Greater Celandine 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 Greater Celandine 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 Greater Celandine

What is Greater Celandine?

Greater Celandine
  • Digestive and gallbladder complaints
  • Stomach cramps and bloating
  • Topical use for warts and skin growths
  • Liver and gallbladder 'cleansing'
  • Mild pain relief

Greater celandine is a traditional herb most often promoted for digestive and gallbladder complaints, but solid human evidence for any use is lacking. More importantly, it has been linked to serious and sometimes severe liver injury, so most experts advise against taking it by mouth. If you are considering it, talk with your pharmacist or doctor first.

Chelidonium majus · Papaveraceae · Aerial parts (leaves, stems, flowers), root, and the yellow-orange latex (sap) · Capsules, tinctures, dried herb for tea, liquid extracts, and topical preparations

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

Greater Celandine: dosing

There is no well-established, standardized safe dose for greater celandine. Products vary widely in how they are made and how much alkaloid they contain, which makes consistent dosing difficult.Given the documented risk of liver injury, we do not recommend a specific dose. If you choose to use a product despite these concerns, follow the directions on the label and do not exceed them.

Sucralfate — available as tablets and oral suspension under brand names including Carafate — is used for the short-term treatment (up to 8 weeks) of active duodenal ulcers.

Carafate tablets and sucralfate tablets are also approved for maintenance therapy — meaning a lower dose taken after an ulcer heals to help keep it from coming back.

Most-Reported Side Effects for Sucralfate

From FAERS, the FDA’s public side-effect reporting system (23,819 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Greater Celandine and Sucralfate Together: Common Questions

Is it safe to take Greater Celandine with Sucralfate?
We do not list a known interaction between Greater Celandine 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.
Do Greater Celandine and Sucralfate have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Greater Celandine 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 Greater Celandine 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 Greater Celandine and Sucralfate combination checked?
Interactions in our licensed database are recorded against drug classes. Sucralfate is filed under 1 classification, and Greater Celandine has documented interactions with 4 drug classes — 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 Greater Celandine interact with any other medications?
Yes. Greater Celandine has 625 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 — Greater Celandine is not one of them. The Sucralfate interaction page linked on this page lists every one, ranked by severity.
