Domperidone is a medication widely used outside the United States to relieve nausea and vomiting and to improve symptoms linked to delayed gastric emptying, such as early satiety, postprandial fullness, upper abdominal discomfort, and reflux. Pharmacologically, domperidone works as a selective dopamine D2/D3 receptor antagonist that acts primarily outside the blood–brain barrier, which can reduce the risk of central nervous system side effects observed with some other antiemetics and prokinetics.

Important U.S. regulatory note: Domperidone is not approved by the U.S. Food and Drug Administration (FDA) for any human use. In the USA, lawful patient access generally occurs through an FDA Expanded Access Investigational New Drug (IND) program when a licensed clinician determines that potential benefits justify potential risks for qualifying conditions, such as severe gastrointestinal motility disorders. Outside the USA, domperidone can be available by prescription or, in some jurisdictions, as a pharmacy medication according to local laws. Always consult a qualified healthcare professional before use and follow the regulations of your country or state.

Domperidone cost and typical pricing

Prices for domperidone vary widely by manufacturer, dosage strength, country of origin, and pack size. In many international markets, the most common strength is 10 mg tablets. While prices are subject to change, typical retail figures from licensed international pharmacies often fall into the following ranges:

• 30 tablets (10 mg): approximately $15–$35 USD (about $0.50–$1.15 per tablet)
• 60 tablets (10 mg): approximately $25–$55 USD (about $0.42–$0.92 per tablet)
• 100–120 tablets (10 mg): approximately $40–$95 USD (about $0.33–$0.95 per tablet)

Bulk packs generally deliver a lower per‑tablet cost. However, oversight by a healthcare professional is essential to confirm a medically appropriate dose and duration. U.S. patients seeking domperidone via the FDA Expanded Access IND route should discuss anticipated costs, physician fees, and pharmacy/compounding charges with their care team in advance.

Note: Pricing estimates are for informational purposes, based on publicly available international pharmacy data. They do not constitute an offer, and actual prices, availability, and shipping timelines may differ.

Where can I buy domperidone in the USA?

In the United States, domperidone is not FDA‑approved for human use and is not available over the counter. U.S. patients typically access domperidone—when clinically justified—through an FDA Expanded Access IND pathway managed by a licensed prescriber. Under this program, a physician submits an application to the FDA and a review board, outlining the rationale, dosing plan, and monitoring protocols, especially with respect to cardiac safety. If approved, a specialty pharmacy or compounding pharmacy authorized under the IND may dispense the medication.

Some patients explore international pharmacy options in countries where domperidone is licensed. While many reputable pharmacies operate globally, U.S. residents should be aware of potential customs limitations, import rules, and the legal requirement for a valid prescription in the destination country. Always confirm that a pharmacy is legitimate, requires appropriate prescriptions when mandated, and sources from licensed manufacturers.

Our platform connects patients with established pharmacy partners that operate in jurisdictions where domperidone is lawfully available. We encourage all U.S. visitors to speak with their healthcare provider regarding the FDA Expanded Access IND route and to follow all federal and state regulations.

Domperidone in the USA: key regulatory facts

Domperidone’s regulatory status in the U.S. reflects concerns about rare but serious cardiac adverse events, including QT prolongation, ventricular arrhythmias, and very rare cases of sudden cardiac death—most often associated with higher doses, in older patients, or when combined with medicines that strongly inhibit CYP3A4 or prolong the QT interval. Because of these risks, U.S. access is restricted to the IND framework, which incorporates specific risk mitigation strategies such as careful patient selection, ECG monitoring when indicated, and dose limitations.

What is domperidone?

Domperidone is a dopamine D2/D3 receptor antagonist that exerts most of its clinical effects outside the central nervous system. By blocking peripheral dopamine receptors in the gastrointestinal tract and the chemoreceptor trigger zone (CTZ) located outside the blood–brain barrier, domperidone can:

• increase lower esophageal sphincter (LES) tone,
• enhance gastric emptying, and
• reduce nausea and vomiting.

Because domperidone has limited penetration into the brain, it generally has a lower risk of central nervous system adverse effects (such as sedation or extrapyramidal symptoms) compared with some centrally acting antiemetics. Nonetheless, individual responses vary, and serious risks—particularly cardiac—must be considered before treatment.

Common uses of domperidone

Outside the United States, clinicians may prescribe domperidone for:

• Short‑term treatment of nausea and vomiting from various causes
• Symptomatic management of gastroparesis (e.g., in diabetic gastroparesis) under specialist supervision
• Functional dyspepsia symptoms, including postprandial fullness and early satiety
• Adjunctive treatment for gastroesophageal reflux in selected cases

Important: The above indications refer to international practice where domperidone is licensed. In the USA, any human use occurs under FDA Expanded Access IND oversight. For lactation enhancement (galactagogue use), the FDA has explicitly advised against domperidone due to safety concerns; U.S. patients should not use domperidone for this purpose.

How domperidone works (mechanism of action)

Domperidone antagonizes dopamine D2/D3 receptors in the gastrointestinal tract, promoting cholinergic activity in the enteric nervous system. The result is improved gastric motility and increased LES pressure in many patients. At the same time, domperidone’s action on dopamine receptors in the chemoreceptor trigger zone helps reduce the sensation of nausea and the reflex of vomiting.

Pharmacokinetics at a glance (may vary by product and patient):

• Onset: often within 30–60 minutes
• Half‑life: approximately 7–9 hours (may be prolonged in renal impairment)
• Metabolism: primarily hepatic via CYP3A4
• Elimination: fecal and urinary routes

Domperidone dosage and administration

Dosing must be individualized by a healthcare professional. Internationally, common adult regimens for nausea or delayed gastric emptying include:

• 10 mg taken three times daily, 15–30 minutes before meals;
• some patients may be advised an additional 10 mg at bedtime.

Regulatory authorities in several countries recommend using the lowest effective dose for the shortest possible time, often limiting the maximum daily dose to 30 mg. In select situations and under specialist care, higher doses may be used in non‑U.S. jurisdictions; however, higher doses may increase cardiac risk. Always follow medical advice specific to your case and locale.

Special populations:

• Older adults (≥60 years): increased risk of QT prolongation and arrhythmia; extra caution and ECG monitoring may be warranted.
• Hepatic impairment: domperidone is not recommended in moderate to severe liver dysfunction.
• Renal impairment: consider extending dosing intervals in significant renal dysfunction.
• Pediatrics: use is restricted or not recommended in many regions; pediatric dosing requires specialist oversight.

How to take domperidone

Take domperidone tablets before meals with a glass of water. Swallow whole; do not crush or chew unless your pharmacist confirms a crushable formulation. If you miss a dose, take it when remembered unless it’s close to the time for your next scheduled dose—do not double up. Avoid grapefruit or grapefruit juice during therapy due to potential interaction with CYP3A4 metabolism.

Safety, risks, and boxed‑warning style cautions

Domperidone has been associated with rare but serious cardiac side effects, including QT interval prolongation, torsades de pointes, and sudden cardiac death. The risk appears higher in patients older than 60 years, at doses above 30 mg/day, and when taken with potent CYP3A4 inhibitors or other QT‑prolonging medications. The decision to use domperidone should always weigh potential benefits against these risks.

Do not use domperidone if you have

• Known prolonged QT interval or underlying significant cardiac disease
• Moderate to severe hepatic impairment
• Uncorrected electrolyte abnormalities (e.g., low potassium or magnesium)
• Known hypersensitivity to domperidone or any excipients

Discuss a baseline and follow-up ECG with your clinician if you are at increased risk for QT prolongation or have cardiac symptoms (e.g., palpitations, syncope). Seek urgent medical attention for fainting, severe dizziness, chest pain, or irregular heartbeat while taking domperidone.

Domperidone side effects

Like all medicines, domperidone can cause side effects. Most are mild and transient, but serious events may occur. Possible side effects include:

• Common: dry mouth, headache, abdominal cramps, diarrhea, constipation, dizziness
• Less common: agitation, insomnia, rash, pruritus
• Hormonal: increases in prolactin may produce galactorrhea, gynecomastia, or menstrual irregularities (report symptoms to your clinician)
• Serious: QT prolongation, ventricular arrhythmias, syncope, sudden cardiac death (seek immediate care for worrisome symptoms)

This is not an exhaustive list. Contact a healthcare professional if you experience side effects, especially anything severe or unusual.

Drug interactions: what to avoid with domperidone

Domperidone is metabolized mainly by CYP3A4. Combining domperidone with strong CYP3A4 inhibitors or medications that prolong the QT interval can substantially raise the risk of serious cardiac events. Always give your clinician and pharmacist a complete list of all prescriptions, OTC drugs, vitamins, and herbal supplements you use.

Medications that may interact with domperidone

• Strong CYP3A4 inhibitors: ketoconazole, itraconazole, fluconazole (high doses), clarithromycin, erythromycin, telithromycin, ritonavir, cobicistat, nefazodone
• QT‑prolonging agents: certain antiarrhythmics (amiodarone, sotalol), some fluoroquinolones (e.g., moxifloxacin), select antipsychotics, methadone, ondansetron, some antidepressants
• Grapefruit products: may increase domperidone exposure; avoid during treatment
• Other pro‑arrhythmic combinations or electrolyte‑depleting drugs without monitoring

Interaction risks vary by dose, patient factors, and concurrent therapies. Your clinician may recommend ECG monitoring, dose adjustments, or selecting an alternative therapy if interactions cannot be safely managed.

Domperidone vs. metoclopramide: a brief comparison

Both domperidone and metoclopramide are used as prokinetics and antiemetics, but they differ in pharmacology and side effect profiles:

• Central effects: Domperidone has limited central nervous system penetration, often reducing the risk of extrapyramidal symptoms compared to metoclopramide.
• Hormonal effects: Domperidone may raise prolactin more often, which can cause galactorrhea or menstrual irregularities.
• Cardiac risk: Domperidone carries specific warnings about QT prolongation and arrhythmias; careful screening and dosing limits are critical.

Choice of therapy depends on the individual’s clinical scenario, comorbidities, and risk factors. Always consult a healthcare professional for tailored advice.

Pregnancy, fertility, and breastfeeding

Domperidone is generally not recommended during pregnancy due to limited safety data and potential risks. In breastfeeding, small amounts may pass into breast milk; however, the FDA advises against domperidone use to increase milk production in the USA because of safety concerns. Discuss family planning, pregnancy status, and lactation with your clinician before starting any therapy.

Practical tips for taking domperidone safely

• Use the lowest effective dose for the shortest duration recommended by your clinician.
• Take doses before meals with water; avoid grapefruit and its juice.
• Report symptoms like palpitations, fainting, severe dizziness, chest pain, or shortness of breath immediately.
• Ask whether an ECG is appropriate before and during treatment—especially if you have cardiac risk factors or are over 60.
• Review all prescription and nonprescription medications with your pharmacist to screen for interactions.

Storage, missed doses, and overdose

Store domperidone tablets at room temperature away from moisture and heat, and keep out of reach of children and pets. If you miss a dose, take it when remembered unless the next dose is due soon. Do not double the dose to catch up. In case of suspected overdose—especially with symptoms such as severe dizziness, fainting, or irregular heartbeat—seek emergency medical care immediately.
