Buttercup + Loperamide, Simethicone
Loperamide, Simethicone brand name: Imodium Advanced.
We found no known interaction between Buttercup and Loperamide, Simethicone 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 Loperamide, Simethicone states a food rule worth keeping to.
Buttercup and Loperamide, Simethicone
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 Loperamide, Simethicone and Buttercup 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 Buttercup at all — not against Loperamide, Simethicone, 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 Loperamide, Simethicone Products Have a Food Rule — Buttercup Should Not Break It
At least one FDA label for a product containing Loperamide, Simethicone says to take it on an empty stomach. Most supplements — Buttercup included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Loperamide, Simethicone on its own and move Buttercup 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 Loperamide, Simethicone 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.
Directions drink plenty of clear fluids to help prevent dehydration caused by diarrhea take only on an empty stomach (1 hour before or 2 hours after a meal) take with a full (8 oz.) glass of water find right dose on chart below.
From the Dosage and Administration section of the FDA label we read for Loperamide, Simethicone — where that label names a specific product, the instruction is that product's.
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 Loperamide, Simethicone page
“Imodium Advanced combines loperamide, an anti-diarrheal opioid that normally stays out of the brain thanks to a transporter called P-glycoprotein, with simethicone for gas, and I treat its interaction list with more respect than most over-the-counter medicines warrant. Thirty-seven of the 82 interacting ingredients on file affect that…”

About Buttercup
What is Buttercup?
- Joint and muscle pain (traditional topical use)
- Skin conditions and blisters
- Nerve pain (traditional folk use)
- Rheumatic complaints
Buttercup refers to plants in the Ranunculus family, which contain an irritating compound that makes the fresh plant toxic to eat and harsh on skin. There is no good scientific evidence that it safely treats any health condition, and it can cause serious irritation and poisoning. We do not recommend using fresh buttercup as a supplement.
Ranunculus spp. · Ranunculaceae · Whole plant, leaves, and flowers (fresh or dried) · Topical preparations, homeopathic remedies, traditional poultices, and dried herb
An interaction check asks whether these two react with each other — it does not ask whether Buttercup is a good idea for someone in your situation. Here is what our Buttercup record says about it on its own.
Buttercup: dosing
There is no established safe dose of buttercup for internal use, and we do not recommend taking it by mouth. The plant is toxic in its fresh form, and standardized supplement products are not available from reputable sources.Any homeopathic preparations are extremely diluted and are a different category of product.
