Drug & supplement interaction

Lesser Celandine + Colestipol

Colestipol brand name: Colestid.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Lesser Celandine and Colestipol 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 Colestipol 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.

Lesser Celandine and Colestipol

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 Colestipol and Lesser 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Lesser Celandine at all — not against Colestipol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

No Interaction Found — But Data Suggests Lesser Celandine and Colestipol May Share a Side Effect

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.

  • Diarrhea Additional detail

    Lesser Celandine

    “Orally, lesser celandine may cause severe gastrointestinal irritation, colic, diarrhea, and irritation of the urinary tract (18). One report associates the use of lesser celandine with a case of recurrent, acute hepatitis.

    Topically, lesser celandine can cause mucous membrane and skin irritation (18). Extended contact with fresh, bruised plant can cause blisters (18).”

How to take them

Some Colestipol Products Have a Food Rule — Lesser Celandine Should Not Break It

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

Patients should take other drugs at least one hour before or four hours after colestipol hydrochloride tablets to minimize possible interference with their absorption.

From the Dosage and Administration section of the FDA label we read for Colestipol — 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 Colestipol

From our pharmacist’s overview on the Colestipol page

“Take colestipol (Colestid), a cholesterol drug that works by trapping bile acids in your gut, and nearly every one of the 18 supplement interactions on file comes down to absorption. Only one rates major, activated charcoal, and it belongs at the top of your reading.”

About Lesser Celandine

What is Lesser Celandine?

  • Hemorrhoids
  • Skin sores and itching
  • Scurvy (historically, as a spring green)
  • Minor wounds

Lesser Celandine is a small spring wildflower with a long folk reputation for treating hemorrhoids (one of its old names is 'pilewort'). There is very little modern scientific evidence that it works for any condition, and the fresh plant is irritating and can be toxic if used improperly. It is best avoided as an internal supplement, and you should talk to a pharmacist or doctor before using it.

Ficaria verna · Ranunculaceae · Aerial parts (leaves and flowers) and root · Traditional ointments, tinctures, and dried herb preparations

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

Lesser Celandine: dosing

There is no established or standardized dose for Lesser Celandine. It is not a common commercial supplement, and reliable dosing information from clinical research does not exist.If you are considering a traditional product that contains it, follow the product label exactly and do not use the fresh plant on your own.

About Colestipol

What Is Colestipol Used For?

Brand name: Colestid

Colestipol — available as oral suspension and tablets under brands including Colestid, Flavored Colestid, and Colestipol Hydrochloride — is used as part of a broader treatment plan (including diet) to lower elevated LDL cholesterol in adults with primary hypercholesterolemia (a condition where LDL cholesterol stays high despite dietary changes).

It is not a standalone fix. Diet, weight management, and other lifestyle changes come first, and colestipol is added when those steps alone aren't enough to reach target LDL levels.

Taking Lesser Celandine and Colestipol Together: Common Questions

Is it safe to take Lesser Celandine with Colestipol?
We do not list a known interaction between Lesser Celandine and Colestipol. 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 Lesser Celandine and Colestipol have any of the same side effects?
Yes — our sources link each of them separately to one 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 Lesser Celandine and Colestipol at the same time of day?
At least one FDA label for a product containing Colestipol 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 Colestipol on its own and move Lesser 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.
Does Colestipol interact with any supplements?
Yes. Colestipol has documented interactions with 18 supplements in our database — Lesser Celandine is not one of them. The Colestipol interaction page linked on this page lists every one, ranked by severity.
