The newer antifungal agents are increasingly being used for the treatment of onychomycosis. Tinea unguium is uncommon in children. In young children who are unable or unwilling to swallow capsules, the alternative to itraconazole capsules may be the oral solution. The pharmacokinetics of the itraconazole capsule when it is broken open and the contents sprinkled onto food has not been reported. Two sisters, ages 8 and 11 years, presented with fingernail dystrophy that was confirmed to be onychomycosis due to Trichophyton rubrum and T. soudanense, respectively. The patients were reluctant to swallow capsules and were treated with itraconazole pulse therapy using the oral solution, 3 mg/kg/day. The treatment regimen consisted of two pulses, each 1 week long, with a 3-week period between pulses. Both patients were clinically and mycologically cured with no adverse effects. Itraconazole oral solution (3 mg/kg/day) given as pulse therapy may be a consideration in the treatment of onychomycosis in some children.
