domperidone use in children dose contraindications age 12 years FDA EMA

Short answer: Yes, domperidone tablets can be used in a 13-year-old boy for nausea/vomiting, but only if he weighs 35 kg or more, only under medical supervision, at the lowest effective dose for the shortest time (usually not more than a week), and only after ruling out cardiac risk factors and drug interactions.

Why age 13 is on the "allowed" side of the cutoff

Following EMA and UK MHRA safety reviews, domperidone's licensed indication was narrowed:
  • Approved use: adults and adolescents 12 years and older, weighing 35 kg or more, for relief of nausea and vomiting.
  • Below 12 years or under 35 kg: no longer approved, because a randomized placebo-controlled trial in children under 12 with acute gastroenteritis showed no efficacy benefit over placebo (MHRA/GOV.UK drug safety update).
So a 13-year-old technically meets the age criterion - but the 35 kg weight threshold must also be met. If he weighs less than 35 kg, it falls outside the licensed use and an alternative should be considered with the treating doctor.
Note: in the US, domperidone is not FDA-approved at all (marketed use is essentially unavailable due to cardiac arrhythmia risk); this age/weight-based approval applies to EMA/UK/many Asian and other markets. Check what applies in your country.

Dosing (if appropriate to use)

  • 10 mg up to 3 times daily, maximum 30 mg/day
  • Lowest effective dose, for the shortest duration possible (guideline default: not usually beyond ~1 week) (FAMHP flash safety update)

Before giving it, check for contraindications/cautions

Domperidone carries a boxed cardiac warning - it can cause QT prolongation, ventricular arrhythmia, and rarely sudden cardiac death, which is why its use has been restricted in Europe to short durations ("Domperidone," Yamada's Textbook of Gastroenterology, 7th ed.). Avoid or use with extra caution if the child has:
  • Known heart disease, arrhythmia, or prolonged QT interval
  • Significant electrolyte disturbances (e.g., hypokalemia)
  • Is on other QT-prolonging drugs or potent CYP3A4 inhibitors (azole antifungals, some macrolides like erythromycin/clarithromycin, certain antivirals) - these raise domperidone levels and arrhythmia risk, since it's metabolized via CYP3A4 (Goldman-Cecil Medicine)
  • Moderate-to-severe liver impairment
  • A prolactin-secreting pituitary tumor
  • GI obstruction, perforation, or active GI bleeding

Bottom line

A 13-year-old is in the approved age bracket only if he also weighs ≥35 kg, and even then domperidone should be prescribed by a doctor who has checked for cardiac risk factors and interacting medications, used at the lowest dose, and stopped once symptoms resolve (ideally within a week). This isn't a drug to self-administer or continue long-term without medical follow-up - please have his pediatrician confirm the indication, weight-based eligibility, and screen for the cautions above before giving it.
Recent literature check: a 2023 pediatric review ("Drugs in Focus: Domperidone," J Pediatr Gastroenterol Nutr, PMID 37159421) reinforces this same age/weight-restricted, short-course approach and cardiac safety caveat - consistent with the textbook and regulatory guidance above, no contradicting recent evidence found.
