Can Hidrasec (racecadotril) be administered to a 4‑month‑old infant?

Hidrasec (Racecadotril) Use in a 4-Month-Old Infant

Racecadotril can be safely administered to a 4-month-old infant as adjunctive therapy to oral rehydration solution for acute diarrhea, at a dose of 1.5 mg/kg three times daily. 1, 2

Evidence Supporting Use in Young Infants

The safety and efficacy of racecadotril has been established in infants as young as 3 months of age through multiple clinical trials. 2, 3

• Age range studied: Clinical trials have specifically included infants from 3 months to 5 years, with mean ages around 12-13 months, demonstrating safety in this vulnerable population. 2, 3

• Dosing: The standard dose is 1.5 mg/kg administered orally three times daily (every 8 hours) as an adjunct to oral rehydration therapy. 2, 3

Clinical Benefits in Young Infants

Racecadotril provides measurable clinical benefits when added to standard oral rehydration therapy:

• Stool output reduction: Studies show a 46-50% reduction in stool output during the first 48 hours of treatment compared to oral rehydration alone. 2, 3

• Duration of diarrhea: The median duration of diarrhea is significantly shortened to approximately 28 hours with racecadotril versus 52-72 hours with placebo. 3

• Reduced rehydration needs: Racecadotril may reduce the risk of rehydration failure and decreases the total intake of oral rehydration solution required. 4

Safety Profile

The drug has an excellent safety profile in young infants:

• Mechanism: Racecadotril works by inhibiting enkephalinase, providing antisecretory effects without affecting intestinal motility, which distinguishes it from loperamide and makes it safer in young children. 1, 5

• Adverse events: Only mild and transient adverse events have been reported, with no serious adverse events attributed to racecadotril in pediatric studies. 5, 2, 3

• Overall tolerability: The rate of adverse events is similar to placebo (RR 0.90,95% CI 0.66 to 1.22). 4

Important Contraindications and Caveats

Avoid racecadotril in specific clinical scenarios:

• Bloody diarrhea: Do not use if blood is present in stools, as it might worsen outcomes. 1

• Febrile diarrhea: Avoid in cases of diarrhea accompanied by fever, where bacterial or invasive pathogens are more likely. 1

Treatment Algorithm

1. Assess the infant: Confirm acute watery diarrhea without blood or fever
2. Initiate oral rehydration: Begin appropriate oral rehydration solution as the primary treatment per WHO recommendations 1
3. Add racecadotril: Administer 1.5 mg/kg orally every 8 hours as adjunctive therapy 2, 3
4. Monitor response: Expect reduction in stool output within 24-48 hours 2, 3
5. Continue treatment: Maintain therapy until diarrhea resolves, typically within 28-72 hours 3

Geographic Availability

Note that racecadotril is not available in North America but is widely used in many other countries including Europe, Latin America, Africa, and Asia. 1
