What Is Metoclopramide? Uses, Dosage, and What You Need to Know in 2026

Metoclopramide is one of the most commonly prescribed medications for stomach motility problems and nausea. Whether you've just been prescribed it for the first time or want to understand more about a medication you've been taking, this guide covers everything you need to know — in plain language.

What Is Metoclopramide?

Metoclopramide is a prescription medication classified as a prokinetic agent and antiemetic (anti-nausea drug). It works by blocking dopamine receptors in the brain's nausea center and in the GI tract, which simultaneously reduces nausea and speeds up the movement of food through the stomach and into the intestines.

It has been FDA-approved since 1979 (injectable) and 1980 (oral), making it one of the older but still widely used GI medications. Generic versions have been available since 1985, which is why it is one of the most affordable prescription drugs in this category.

The most well-known brand name is

Reglan. Other brand names include Metozolv ODT (orally disintegrating tablet) and Gimoti (nasal spray formulation, for diabetic gastroparesis in adults who cannot take oral medications).

What Is Metoclopramide Used For?

Metoclopramide has several FDA-approved uses:

1. Diabetic gastroparesis: Metoclopramide is the only FDA-approved oral medication for this condition. Gastroparesis means the stomach empties too slowly, causing symptoms like nausea, vomiting, bloating, heartburn, and feeling full long after eating.
2. GERD (gastroesophageal reflux disease): For patients with heartburn and esophageal damage who haven't responded to other treatments like PPIs. Used for 4–12 weeks.
3. Chemotherapy-induced nausea and vomiting: Parenteral (IV) metoclopramide is FDA-approved for preventing and treating nausea from chemotherapy.
4. Small bowel intubation procedures: IV metoclopramide helps move tubes through the stomach during GI procedures.

Common off-label uses include: acute migraine with nausea (especially in ERs), post-surgical nausea, and nausea of pregnancy (though evidence is limited and use during pregnancy carries considerations).

What Forms Does Metoclopramide Come In?

• Tablets: 5 mg and 10 mg (most common outpatient form)
• Orally Disintegrating Tablets (ODT): Dissolve on the tongue; good for people who have difficulty swallowing pills
• Oral solution (liquid): 5 mg per 5 mL; useful for children (when used off-label) or patients with swallowing difficulties
• Injectable: 5 mg/mL; used in hospitals and clinics for IV or IM dosing
• Nasal spray (Gimoti): 15 mg per actuation; for diabetic gastroparesis patients who cannot take oral medications

Metoclopramide Dosage: How to Take It

The standard adult dose for both gastroparesis and GERD is:

• 10–15 mg four times daily, taken 30 minutes before each meal and at bedtime
• Maximum treatment duration: 12 weeks (to minimize the risk of tardive dyskinesia)
• Take on an empty stomach if possible — food can reduce absorption

For ODT tablets: place on the tongue and let it dissolve — you don't need water. Do not swallow it whole or chew it. Use dry hands to remove it from packaging.

Important Safety Warnings

• Do not take for longer than 12 weeks — increased risk of permanent tardive dyskinesia
• Do not drive or operate machinery until you know how metoclopramide affects you — it causes significant drowsiness in some patients
• Avoid alcohol — adds to CNS depression from metoclopramide
• Tell your doctor about all medications you take, especially antipsychotics, MAOIs, antidepressants like fluoxetine or paroxetine, and any sedatives
• Not recommended for patients with Parkinson's disease, epilepsy, pheochromocytoma, GI obstruction, or a history of tardive dyskinesia

Is Metoclopramide a Controlled Substance?

No. Metoclopramide is not a DEA-scheduled controlled substance. It can be prescribed by any licensed healthcare provider, including via telehealth, without special restrictions. It can be refilled more than once per prescription in most states.
