Mebendazole Dosing for a 50 kg Child
For a child weighing 50 kg, administer mebendazole 100 mg twice daily for 3 consecutive days, regardless of the specific helminth infection being treated. 1
Standard Pediatric Dosing
The recommended dose is 100 mg twice daily for 3 days for all children, independent of weight or age, as this regimen has been validated across multiple studies and guideline recommendations 1, 2, 3
This dosing applies uniformly to common soil-transmitted helminth infections including:
Critical Administration Details
Tablets should be chewed for optimal absorption, not swallowed whole 1
The full 3-day course must be completed even if symptoms improve before completion 1
Efficacy Considerations by Parasite Type
For hookworm infections specifically, the multiple-dose regimen (100 mg twice daily for 3 days) achieves 98% cure rates, vastly superior to single-dose therapy which only achieves 13% cure rates 4
For severe or symptomatic trichuriasis, some children may require a 6-day course (100 mg twice daily for 6 days) or repeat treatment cycles to achieve complete parasite eradication 5, 6
Ascariasis shows excellent response with standard 3-day therapy, achieving >99% egg reduction rates 2, 3
Re-treatment Protocol
Re-treatment may be necessary in areas with high reinfection rates, particularly for hookworm and whipworm infections 1
For treatment failures in trichuriasis, consider extending therapy to 6 days or administering a repeat 3-6 day course 5, 6
