Drug & supplement interaction

Corn Poppy + Vedolizumab

Vedolizumab brand name: Entyvio.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Corn Poppy and Vedolizumab 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 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.

Corn Poppy and Vedolizumab

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 Vedolizumab and Corn Poppy 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.

Corn Poppy safety at a glance

Corn Poppy overall Use caution Generally low in strong alkaloids, but human safety data are limited and it should be used cautiously.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough 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 Vedolizumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Vedolizumab is filed under a single classification — hepatotoxic drugs. Corn Poppy has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Vedolizumab’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.

No Interaction Found — But Data Suggests Corn Poppy and Vedolizumab 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. One of them is worth acting on rather than waiting out — marked below.

From our pharmacist’s overview on the Vedolizumab page

“Every entry on this page points at the same organ, the liver. Vedolizumab (Entyvio) is a gut-selective biologic for ulcerative colitis and Crohn's disease, and though it does most of its work in the intestine, it has been linked to liver injury in rare cases.”

About Corn Poppy

What is Corn Poppy?

Corn Poppy
  • Cough and sore throat
  • Sleep and restlessness
  • Mild pain
  • Anxiety and nervousness
  • Digestive complaints

Corn poppy is a red-flowered plant traditionally used in teas and syrups for cough, sleep, and mild pain. Solid human research is very limited, so its benefits are not well proven, and unlike its relative the opium poppy, it contains only small amounts of weak alkaloids. Talk to a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Papaver rhoeas · Papaveraceae · Flowers (petals) and leaves · Tea, syrup, dried petals, tincture, capsules

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

Corn Poppy: dosing

There is no well-established or standardized dose for corn poppy. Traditional use generally involves small amounts of the dried petals made into a tea or syrup.Because products vary widely in strength, follow the directions on the product label and do not exceed the suggested amount. Avoid giving it to infants or young children.

Vedolizumab is filed under 1 classification, and Corn Poppy has documented interactions with 1 drug class — none of Vedolizumab's classifications are among them.
