Fool's Parsley + Eluxadoline
Eluxadoline brand name: Viberzi.
We found no known interaction between Fool's Parsley and Eluxadoline 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 Eluxadoline states a food rule worth keeping to.
Fool's Parsley and Eluxadoline
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 Eluxadoline and Fool's Parsley 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 Fool's Parsley at all — not against Eluxadoline, 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 Eluxadoline Products Have a Food Rule — Fool's Parsley Should Not Break It
At least one FDA label for a product containing Eluxadoline says to take it with food. If you take Fool's Parsley on an empty stomach out of habit, keep them separate — and take Eluxadoline with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Eluxadoline 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 DOSAGE AND ADMINISTRATION The recommended dosage of VIBERZI is 100 mg taken orally twice daily with food.
From the Dosage and Administration section of the FDA label we read for Eluxadoline — 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 Eluxadoline page
“One supplement here can keep a dose of eluxadoline (Viberzi) from being fully absorbed. Activated charcoal soaks up oral medicines in the gut, and of the 23 supplements and herbs with an interaction on file, it is the only one rated major, reason enough to give this page a careful read.”

About Fool's Parsley
What is Fool's Parsley?
- Digestive complaints (traditional/homeopathic)
- Diarrhea in children (homeopathic tradition)
- Nausea and vomiting (homeopathic tradition)
- Restlessness (homeopathic tradition)
Fool's Parsley is a poisonous weed that closely resembles edible parsley and has no proven medicinal benefit. The raw plant is toxic and should never be eaten; the only modern use is in highly diluted homeopathic products, which lack reliable evidence of effectiveness. If you are looking for a culinary herb, do not gather wild plants that resemble parsley.
Aethusa cynapium · Apiaceae · Whole plant (aerial parts), occasionally used in homeopathic preparations · Homeopathic dilutions; rarely as crude plant material (not recommended)
An interaction check asks whether these two react with each other — it does not ask whether Fool's Parsley is a good idea for someone in your situation. Here is what our Fool's Parsley record says about it on its own.
Fool's Parsley: dosing
There is no established safe medicinal dose of Fool's Parsley. The crude plant is poisonous and should not be taken at any amount.For homeopathic products, dosing follows the directions on the specific product label, but these are not standardized medical doses and are not supported by strong evidence.
