No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Corn Poppy and Nifedipine 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 Nifedipine

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 Nifedipine 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 Nifedipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nifedipine is filed under 9 classifications — including calcium channel blockers, cytochrome p450 3a4 (cyp3a4) inhibitors, antihypertensive drugs. Corn Poppy has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Nifedipine’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 Nifedipine 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.

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 Nifedipine

What Is Nifedipine Used For?

Brand names: Procardia XL, Adalat PA, Adalat, Nifedin, Nifed PA, Nifed, Procardia, Adalat XL, Adalat CC, Adalat LA, Adalat Retard, Adipine MR, Adipine XL, Cardilate MR, Coracten SR, Coracten XL, Fortipine LA 40, Hypolar Retard 20, Nifedipress MR, Nifopress Retard, Tensipine MR

Nifedipine treats high blood pressure (hypertension), chronic stable angina (chest pain brought on by physical effort), and vasospastic angina (chest pain caused by spasm of the coronary arteries, sometimes called Prinzmetal's angina). Lowering blood pressure with nifedipine helps reduce the risk of strokes and heart attacks.

The capsule form is approved for vasospastic angina and chronic stable angina only — it is not approved for high blood pressure. The extended-release tablet (including Procardia) covers all three uses: vasospastic angina, chronic stable angina, and high blood pressure.

Taking Corn Poppy and Nifedipine Together: Common Questions

Is it safe to take Corn Poppy with Nifedipine?
We do not list a known interaction between Corn Poppy and Nifedipine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Corn Poppy and Nifedipine have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Corn Poppy and Nifedipine combination checked?
Interactions in our licensed database are recorded against drug classes. Nifedipine is filed under 9 classifications, and Corn Poppy has documented interactions with 1 drug class — none of Nifedipine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Corn Poppy interact with any other medications?
Yes. Corn Poppy has 248 documented drug interactions in our database — Nifedipine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Nifedipine interact with any supplements?
Yes. Nifedipine has documented interactions with 273 supplements in our database — Corn Poppy is not one of them. The Nifedipine interaction page linked on this page lists every one, ranked by severity.
