Abstract
Ivermectin, an effective treatment for scabies, is not licensed for children weighing <15 kg. Pharmacokinetic modelling has shown a 3 mg dose in young children (2-4 years, weighing 10-14 kg) achieves comparable drug exposure to a 200 μg/kg dose in children aged ≥5 years. This trial evaluated a 3 mg dose in young children.
) after the first dose (compared to a historical control of Indigenous Australian children aged ≥5 years weighing ≥15 kg receiving 200 μg/kg). Secondary outcomes were clinical improvement and adverse effects.
was comparable to the historical control group aged 5-11 years (815 μg h/L vs 953 μg h/L, p = 0.256). Complete resolution of scabies occurred in 90/99 children by day 14. Adverse effects were mild, occurring in 7/99.
comparable to older children, was highly effective in treating scabies and well tolerated. This study supports extending ivermectin treatment to younger children improving global efforts to control this neglected disease.
