Lesser Celandine + Naloxegol
Naloxegol brand name: Movantik.
We found no known interaction between Lesser Celandine and Naloxegol 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 Naloxegol 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 Naloxegol
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 Naloxegol 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 Naloxegol, 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.

Some Naloxegol Products Have a Food Rule — Lesser Celandine Should Not Break It
At least one FDA label for a product containing Naloxegol 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 Naloxegol 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 Naloxegol 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.
(2.1) Take on an empty stomach at least 1 hour prior to the first meal of the day or 2 hours after the meal.
From the Dosage and Administration section of the FDA label we read for Naloxegol — 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.

From our pharmacist’s overview on the Naloxegol page
“Naloxegol (Movantik) relieves the constipation that opioids cause, and this is a list that deserves real care before you add anything from it. Nearly all of the trouble traces to a single enzyme, CYP3A4, which the body relies on to clear naloxegol.”

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.
