Used for vomiting and GI stasis. Higher sensitivity to CNS effects; frenzied behavior reported occasionally. Maropitant often preferred.

What is metoclopramide?

The IUPAC name is 4-amino-5-chloro-N-[2-(diethylamino)ethyl]-2-methoxybenzamide.

Also known as: Methochlopramide, Metochlopramide, Reliveran, Metaclopramide.

IUPAC name: 4-amino-5-chloro-N-[2-(diethylamino)ethyl]-2-methoxybenzamide
CAS number: 364-62-5
Molecular formula: C14H22ClN3O2
Molecular weight: 299.8 g/mol
SMILES: CCN(CC)CCNC(=O)c1cc(Cl)c(N)cc1OC

Risk for dogs

Low risk

First-line antiemetic and prokinetic agent. Generally well-tolerated; extrapyramidal signs at high doses. Used widely in chemo-induced nausea.

Risk for cats

Moderate risk

Used for vomiting and GI stasis. Higher sensitivity to CNS effects; frenzied behavior reported occasionally. Maropitant often preferred.

Regulatory consensus

2 regulatory and scientific bodies have classified Metoclopramide. The classifications differ — that's the data.

Agency	Year	Classification	Notes
FDA	2009	Approved human drug (NDA 017854); black box warning for tardive dyskinesia
EMA	2013	Approved; restricted to short-term use ≤5 days

Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.

Safer alternatives

Lower-risk approaches that achieve a similar outcome to Metoclopramide:

Ondansetron (fewer extrapyramidal effects)
Trade-offs: Removes 95-99% of dissolved contaminants including metals, PFAS, nitrates; wastes 2-4 gallons per gallon produced (improving with newer systems); removes beneficial minerals; $0.05-0.25/gallon; requires pre-treatment for longevity.

Relative cost: 1.2-2×
Maropitant / Cerenia (veterinary-specific)
Trade-offs: Removes 95-99% of dissolved contaminants including metals, PFAS, nitrates; wastes 2-4 gallons per gallon produced (improving with newer systems); removes beneficial minerals; $0.05-0.25/gallon; requires pre-treatment for longevity.

Relative cost: 1.2-2×
