The bottom line No known interaction

We found no known interaction between Corn Poppy and Glycerol Phenylbutyrate 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 Glycerol Phenylbutyrate states a food rule worth keeping to.

Corn Poppy and Glycerol Phenylbutyrate

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 Glycerol Phenylbutyrate 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 Glycerol Phenylbutyrate

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

What to actually watch for

What Corn Poppy Itself Has Been Linked To

This is not an interaction — nothing below involves Glycerol Phenylbutyrate. It is the side-effect record for Corn Poppy on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Corn Poppy, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Hives Worth acting on Additional detail

    “Topically, corn poppy flowers may cause allergic contact urticaria.”

Everything above comes from the Natural Medicines adverse-effect record for Corn Poppy — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Glycerol Phenylbutyrate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Glycerol Phenylbutyrate column appears here.

How to take them

Some Glycerol Phenylbutyrate Products Have a Food Rule — Corn Poppy Should Not Break It

At least one FDA label for a product containing Glycerol Phenylbutyrate says to take it with food. If you take Corn Poppy on an empty stomach out of habit, keep them separate — and take Glycerol Phenylbutyrate 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 Glycerol Phenylbutyrate 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.

Instruct patients to take glycerol phenylbutyrate oral liquid with food or formula and to administer directly into the mouth via oral syringe.

From the Dosage and Administration section of the FDA label we read for Glycerol Phenylbutyrate — where that label names a specific product, the instruction is that product's. See the Glycerol Phenylbutyrate drug page ›

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 Glycerol Phenylbutyrate

This page covers Corn Poppy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Glycerol Phenylbutyrate page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Glycerol Phenylbutyrate page

“Ravicti (glycerol phenylbutyrate) pulls ammonia out of the blood in people with urea cycle disorders, so a dose that never gets absorbed is not a small problem, it can let ammonia climb toward dangerous levels. That is why this list deserves real attention even though it is short.”

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.

About Glycerol Phenylbutyrate

What Is Glycerol Phenylbutyrate Used For?

Brand name: Ravicti

Glycerol phenylbutyrate oral liquid — available as the brand Ravicti and as a generic — is used for the long-term (chronic) management of urea cycle disorders (UCDs). UCDs are rare inherited conditions where the body cannot properly convert ammonia into urea, causing toxic ammonia levels to build up in the blood and brain.

It is used in patients whose ammonia cannot be controlled by a low-protein diet and/or amino acid supplements alone. It must always be used alongside dietary protein restriction and, in some cases, additional dietary supplements such as essential amino acids, arginine, or citrulline. It is not for treating a sudden, severe spike in ammonia (acute hyperammonemia), and its safety and effectiveness for N-acetylglutamate synthase (NAGS) deficiency have not been established.

Is it safe to take Corn Poppy with Glycerol Phenylbutyrate?
