Treatment for Scalp Ringworm (Tinea Capitis) in Children

First-Line Treatment Options

The British Journal of Dermatology recommends oral antifungal therapy as the standard of care for tinea capitis in children, with the choice of medication depending on the causative organism and local epidemiology 1, 2
Griseofulvin is recommended at a dosage of 15-20 mg/kg/day for 6-8 weeks, and is the only antifungal agent licensed specifically for tinea capitis in young children in many countries 1, 2, 3
Griseofulvin is more effective against Microsporum species (88.5% response rate) compared to Trichophyton species (67.9% response rate) 2, 3
Terbinafine is recommended at a dosage of 62.5 mg per day for 2-4 weeks for children under 20 kg, and is more effective against Trichophyton species than Microsporum species 1, 2, 5

The British Journal of Dermatology recommends obtaining a proper diagnosis through scalp lesions sampling via scraping, hair pluck, brush or swab for microscopy and culture when possible 1
Treatment should be started based on clinical presentation, and the antifungal should be selected based on the suspected organism, with Terbinafine preferred for Trichophyton species and Griseofulvin preferred for Microsporum species 1, 2

Children receiving appropriate therapy can attend school or nursery, and family members and close contacts should be screened if T. tonsurans is identified 5
The endpoint of treatment is mycological rather than clinical cure, and repeat mycology sampling is recommended until clearance is achieved 5

Topical therapy alone is not effective for tinea capitis and should not be used as monotherapy, and treatment failure may be due to poor compliance, suboptimal absorption, or relative insensitivity of the organism 1, 5
If clinical improvement occurs but mycology remains positive, current therapy should be continued for an additional 2-4 weeks 5
Terbinafine is less effective for Microsporum infections and may lead to treatment failures if used as first-line therapy for these infections 1, 2
