Serrapeptase + Metoclopramide Hydrochloride

Metoclopramide Hydrochloride brand name: Gimoti.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Serrapeptase 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.

Serrapeptase 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 Serrapeptase 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.

Serrapeptase safety at a glance

Serrapeptase overall Use caution Generally tolerated short-term, but long-term safety is not well studied.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid No reliable safety information, so avoid 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 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. Serrapeptase has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (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.

No Interaction Found — But Data Suggests Serrapeptase and Metoclopramide Hydrochloride 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.

Reported for Serrapeptase but not commonly for Metoclopramide Hydrochloride: stomach upset.

Effects for Metoclopramide Hydrochloride come from the ADVERSE REACTIONS section of its FDA label; effects for Serrapeptase come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 76,710 voluntary FDA FAERS reports for Metoclopramide Hydrochloride that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Metoclopramide Hydrochloride Is Prescribed For, and What Serrapeptase 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. Serrapeptase 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).

Serrapeptase has been studied for:

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

    Serrapeptase for diabetes

    Although there has been interest in using oral serrapeptase for diabetes, there is insufficient reliable information about the clinical effects of serrapeptase for this purpose.

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 Serrapeptase for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Serrapeptase

What is Serrapeptase?

  • Inflammation and swelling
  • Sinus and respiratory congestion
  • Pain after surgery or injury
  • Joint and back pain
  • Thinning mucus

Serrapeptase is an enzyme marketed to reduce inflammation, swelling, pain, and mucus, but the human evidence is limited and mostly low quality. If you want to try it, choose an enteric-coated product, follow the label, and check with your pharmacist or doctor first—especially if you are pregnant, breastfeeding, or take other medicines.

Enzyme produced by bacteria (Serratia species) found in silkworms · Tablets, capsules (often enteric-coated)

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

Serrapeptase: dosing

There is no official or well-established dose for serrapeptase. Products are often measured in enzyme "units" rather than simple milligrams, and these vary between brands.The best approach is to follow the directions on the product label and not exceed them.

Taking Serrapeptase and Metoclopramide Hydrochloride Together: Common Questions

Is it safe to take Serrapeptase with Metoclopramide Hydrochloride?
We do not list a known interaction between Serrapeptase 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 Serrapeptase and Metoclopramide Hydrochloride 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.
Are Serrapeptase 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 Serrapeptase in each. That is a conversation for your prescriber, especially if Metoclopramide Hydrochloride is being adjusted to a target.
How was the Serrapeptase and Metoclopramide Hydrochloride combination checked?
Interactions in our licensed database are recorded against drug classes. Metoclopramide Hydrochloride is filed under 5 classifications, and Serrapeptase has documented interactions with 1 drug class — 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 Serrapeptase interact with any other medications?
Yes. Serrapeptase has 122 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 — Serrapeptase is not one of them. The Metoclopramide Hydrochloride interaction page linked on this page lists every one, ranked by severity.
