No Known Interaction

The bottom line No known interaction

We found no known interaction between Corn Silk and Metoclopramide Hydrochloride 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.

Interaction report

Corn Silk and Metoclopramide Hydrochloride

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 Metoclopramide Hydrochloride and Corn Silk 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 Silk safety at a glance

Corn Silk overall Use caution Generally well tolerated for short-term use, but human safety data are limited.

Pregnancy Avoid Not enough reliable safety data, so it is best avoided during pregnancy.

Breastfeeding Possibly Safe When consumed in food amounts. Insufficient reliable information available when used as medicine; avoid using. Read the full breastfeeding detail

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Metoclopramide Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Metoclopramide Hydrochloride is filed under 5 classifications — including serotonergic drugs, serotonergic drugs, cytochrome p450 2d6 (cyp2d6) substrates. Corn Silk has documented interactions with 5 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and corticosteroids (moderate) — and none of Metoclopramide Hydrochloride’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

No Interaction Found — But Data Suggests Corn Silk and Metoclopramide Hydrochloride May Share Several of the Same Side Effects

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.

Overlapping uses

What Metoclopramide Hydrochloride Is Prescribed For, and What Corn Silk Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Metoclopramide Hydrochloride is a prescription medicine with approved uses on its FDA label. Corn Silk is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Metoclopramide Hydrochloride is prescribed for: Gimoti (metoclopramide nasal spray) is approved for adults with acute and recurrent diabetic gastroparesis — a condition where diabetes damages the nerves controlling stomach emptying, causing nausea, vomiting, and bloating. It works to relieve those symptoms by helping the stomach empty more normally. Gimoti is not recommended for children, or for adults with moderate to severe kidney or liver disease. It is also not recommended for adults taking strong CYP2D6 inhibitor medications (certain antidepressants and other drugs that slow how the body breaks down metoclopramide).

Corn Silk has been studied for:

Diabetes studied, not established Corn Silk has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Corn Silk for diabetes

It is unclear if oral corn silk is beneficial in patients with diabetes.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Metoclopramide Hydrochloride on your own; if you are taking Corn Silk for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Corn Silk

What is Corn Silk?

Urinary tract and bladder problems
Mild fluid retention (diuretic)
Kidney and prostate concerns
Bedwetting in children
Soothing urinary irritation

Corn silk is a traditional herbal remedy taken as a tea or extract, mostly for urinary and mild fluid-related complaints. High-quality human evidence for these uses is limited, so it should not replace proven treatments. It is generally considered low-risk for short-term use in healthy adults, but talk with your pharmacist or doctor before trying it.

Zea mays · Poaceae · Stigmas and styles (the silky strands) of the corn ear · Tea, dried herb, liquid extract/tincture, capsules

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

Corn Silk: dosing

There is no official, standardized dose for corn silk. It has traditionally been taken as a tea made by steeping dried corn silk in hot water, or as a liquid extract or capsule.Because product strengths vary widely, the best advice is to follow the directions on the product label and not exceed them.

Taking Corn Silk and Metoclopramide Hydrochloride Together: Common Questions

Is it safe to take Corn Silk with Metoclopramide Hydrochloride?

We do not list a known interaction between Corn Silk and Metoclopramide Hydrochloride. 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 Silk and Metoclopramide Hydrochloride have any of the same side effects?

Yes — our sources link each of them separately to 2 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.

Are Corn Silk and Metoclopramide Hydrochloride used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Corn Silk in each. That is a conversation for your prescriber, especially if Metoclopramide Hydrochloride is being adjusted to a target.

How was the Corn Silk and Metoclopramide Hydrochloride combination checked?

Interactions in our licensed database are recorded against drug classes. Metoclopramide Hydrochloride is filed under 5 classifications, and Corn Silk has documented interactions with 5 drug classes — none of Metoclopramide Hydrochloride'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 Silk interact with any other medications?

Yes. Corn Silk has 290 documented drug interactions in our database — Metoclopramide Hydrochloride 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 Metoclopramide Hydrochloride interact with any supplements?

Yes. Metoclopramide Hydrochloride has documented interactions with 135 supplements in our database — Corn Silk is not one of them. The Metoclopramide Hydrochloride interaction page linked on this page lists every one, ranked by severity.
