Cramp Bark 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 Cramp Bark 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Cramp Bark at all — not against Metoclopramide Hydrochloride, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What Metoclopramide Hydrochloride’s Own FDA Label Lists

This is not an interaction — none of it involves Cramp Bark. These are the most notable effects listed in the ADVERSE REACTIONS section of Metoclopramide Hydrochloride’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Serotonin syndrome Worth acting on
  • Thoughts of self-harm Worth acting on
  • A slow heartbeat Worth acting on
  • Hallucinations Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on
  • Wheezing Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on

Showing the 10 most notable of 35 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Metoclopramide Hydrochloride. Read the label on DailyMed › 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. Cramp Bark’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cramp Bark side to compare — that is a limit of the record, not a statement that Cramp Bark has no side effects.

Overlapping uses

What Metoclopramide Hydrochloride Is Prescribed For, and What Cramp Bark 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. Cramp Bark 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).

Cramp Bark has been studied for:

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

    Cramp Bark for diabetes

    Although there has been interest in using oral Viburnum opulus for diabetes, there is insufficient reliable information about the clinical effects of Viburnum opulus 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 Cramp Bark for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Metoclopramide Hydrochloride page

“Metoclopramide (Gimoti, also sold as Reglan) calms nausea and speeds a slow stomach by acting on the brain, and that is exactly where most of these 135 supplements and herbs collide with it. This is a list to treat with genuine care.”

About Cramp Bark

What is Cramp Bark?

  • Menstrual cramps
  • Muscle spasms
  • General cramping pain
  • Stomach or digestive cramps
  • Easing tension

Cramp Bark is the dried bark of Viburnum opulus, traditionally used to ease muscle and menstrual cramps. Modern, high-quality human studies are very limited, so its effectiveness is not well proven. If you want to try it, talk with your pharmacist or doctor first, and avoid it during pregnancy because safety is unclear.

Viburnum opulus · Adoxaceae · Dried bark · Tea (decoction), tincture, liquid extract, capsules

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

Cramp Bark: dosing

There is no well-established or standardized dose for Cramp Bark. Products vary widely in strength, especially between teas, tinctures, and capsules.The safest approach is to follow the directions on the product label and not exceed them. Because quality and concentration differ between brands, and because little is known about safe long-term use, it is a good idea to review the product with your pharmacist before starting.
