Can domperidone be used as an anti‑emetic in a child under two years old?

Domperidone Use in Children Under Two Years

Domperidone should NOT be used as an antiemetic in children under two years old. The drug is not approved for use in this age group, lacks efficacy data in young children, and carries significant safety concerns including cardiac risks and other adverse effects.

Evidence Against Use in Young Children

Regulatory Status and Approval

• Domperidone is not approved for any indication in humans in the United States 1
• Current European authorization restricts use to children older than 12 years only, for relief of nausea and vomiting, and only for short periods 2
• The 2014 European Medicines Agency restrictions specifically limit use to patients ≤60 years with daily doses ≤30 mg/day for ≤7 days duration 3

Lack of Efficacy in Pediatric Gastroenteritis

• A large randomized controlled trial (2019) in children aged 6 months to 12 years with acute gastroenteritis found no significant difference between low-dose domperidone and placebo in reducing vomiting episodes (32.0% vs 33.8% with no vomiting) 4
• The study was terminated early following futility analysis, demonstrating domperidone with oral rehydration therapy did not differ from placebo 4
• A 2019 comparative study showed ondansetron was significantly more effective than domperidone at 24 hours (95% vs 85% improvement, p=0.01) 5

Safety Concerns in Young Children

Cardiac Risks:

• QT interval prolongation has been documented in infants receiving oral domperidone 6
• Domperidone is listed among QT-interval-prolonging medications in pediatrics 7
• Risk of cardiac arrhythmias including torsades de pointes, particularly when combined with other QT-prolonging drugs 7

Other Adverse Effects:

• Urinary retention has been reported in children as young as 2 years receiving domperidone for acute gastroenteritis 8
• Anti-dopaminergic antiemetic agents should be prescribed with caution, especially in young children 8

Recommended Alternatives

For Children >4 Years with Gastroenteritis

• Ondansetron is the preferred antiemetic for children >4 years of age with acute gastroenteritis associated with vomiting 7
• Ondansetron facilitates tolerance of oral rehydration and reduces immediate need for hospitalization 7

For Children <4 Years with Gastroenteritis

• No routine antiemetic use is recommended for acute gastroenteritis in children <4 years of age 7
• Focus should be on adequate hydration with oral rehydration solution 7

For Migraine-Associated Nausea in Adolescents

• Domperidone can be used for nausea in adolescents aged 12-17 years only, though oral administration is unlikely to prevent vomiting 7
• Metoclopramide is an alternative option for nausea in pregnancy when needed 7

Clinical Pitfalls to Avoid

• Do not use domperidone in children under 12 years for any indication, as it lacks both regulatory approval and demonstrated efficacy 2, 4
• Avoid combining domperidone with other QT-prolonging medications including macrolides, fluoroquinolones, and other antiemetics like ondansetron 7
• Monitor for extrapyramidal symptoms and urinary retention if domperidone is used in older children 8
• The primary treatment for pediatric gastroenteritis remains oral rehydration therapy, not antiemetics 7
