Tinea capitis: diagnostic criteria and treatment options.

Tinea capitis is a fungal infection involving the hair shaft of the scalp. It is commonly referred to as ringworm and occurs primarily in children. Treatment with a systemic anti-fungal rather than topical treatment is required. Currently, two medications, griseofulvin (Grifulvin) and terbinafine (Lamisil Granules), are FDA-approved to treat tinea capitis. Treatment with griseofulvin is usually 6 to 8 weeks, while treatment with terbinafine requires 6 weeks. There are other medications currently not FDA-approved to treat tinea capitis that have similar cure rates and shorter durations of treatment for tinea capitis, and as a result, are being used off-label. This article reviews the research-based literature related to the treatment of tinea capitis with various pharmacologic agents.
