Fluconazole (Diflucan) for Ringworm

Dermatophytosis (Ringworm)

Ringworm is a skin infection with a dermatophyte fungus. Depending on which part of the body is affected, ringworm is given a specific name:

  • Tinea corporis is a ringworm of the body, which affects the glabrous (relatively hairless) skin.
  • Tinea capitis is a ringworm of the scalp.
  • Tinea cruris (also called "jock itch" or ringworm of the groin) affect the groin, perineum, and perianal region.
  • Tinea pedis (also called "athlete's foot") affects foot.

Dosage for ringworm:

  • Tinea corporis, tinea cruris, or tinea pedis: 150 mg once weekly for 2–6 weeks.
  • Tinea capitis (children 1.5–16 years of age): 3–6 mg/kg daily for 2–6 weeks.

How long does it take for fluconazole to work? It usually takes 4-6 week for fluconazole to cure ringworm1.

Tinea versicolor

Tinea versicolor (also known as Pityriasis versicolor) is caused by Malassezia furfur and is not a classic ringworm. Tinea versicolor is relatively harmless fungal infection that results in patches of different pigmentation on the skin. Oral fluconazole may be suitable for extensive or severe infections or when topical antifungals don't work2.

Dosage for tinea versicolor: 300 mg once weekly for 2 weeks.
