Cannabidiol (cbd) and Metoclopramide Hydrochloride

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Cannabidiol (cbd) interacts with whole categories of medication. Metoclopramide Hydrochloride falls into 2 of those categories, so it can interact with Cannabidiol (cbd) in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Metoclopramide Hydrochloride

Metoclopramide Hydrochloride falls under CNS DEPRESSANTS — the group Cannabidiol (cbd) interacts with.

Theoretically, cannabidiol might have additive effects if used with other CNS depressants.
Preliminary clinical research, case reports, and animal studies suggest that high dose cannabidiol has sedative and hypnotic effects. Theoretically, concomitant use of cannabidiol with drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with CBD and metoclopramide (Gimoti). Metoclopramide can already make some people feel drowsy, tired, or a bit foggy. CBD, especially at higher doses, may add its own calming, sleepy effect. Put the two together and you could feel more sluggish or sleepy than you would expect from either one alone.

I'll be honest, this concern is mostly theoretical. It comes from how these substances behave in the body, not from solid studies of this exact combo, so it may not happen to everyone. Still, it's worth watching for. If you notice extra drowsiness, dizziness, or trouble concentrating, go easy on driving and check in with your pharmacist or doctor before changing anything.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

2 of 2

Metoclopramide Hydrochloride also falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES.

Theoretically, cannabidiol might increase levels of drugs metabolized by CYP2D6.
In vitro research shows that cannabidiol inhibits CYP2D6. Theoretically, concomitant use of cannabidiol with CYP2D6 substrates might increase the risk for adverse effects from these substrates. However, a clinical crossover trial in healthy adults shows that cannabidiol does not inhibit dextromethorphan, a substrate of CYP2D6.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: your body uses a liver enzyme called CYP2D6 to help clear metoclopramide. In test-tube studies, CBD can slow that enzyme down. If that happened in real life, metoclopramide could build up a bit, which might make its side effects more noticeable. With this drug, that means things like drowsiness, restlessness, muscle twitching, or unusual movements of the face or limbs.

That said, this is mostly a theory based on lab work. A human study found CBD did not actually block CYP2D6 for another drug it processes, so the real-world risk looks low. Still, since metoclopramide can cause movement-related effects, it's worth a quick chat with your pharmacist or doctor before pairing the two.

About Cannabidiol (cbd)

What is Cannabidiol (cbd)?

  • Anxiety and stress
  • Sleep problems
  • Chronic pain
  • Certain seizure disorders
  • Inflammation

CBD is a compound from the cannabis (hemp) plant that does not cause a 'high.' It has strong evidence only for certain rare seizure disorders (as a prescription drug), while most other popular uses are still backed by limited or early research. Product quality varies a lot, so talk with your pharmacist or doctor before using it, especially if you take other medicines.

About Metoclopramide Nasal Spray

What Is Metoclopramide Nasal Spray Used For?

Brand name: Gimoti

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).
