What is ketoconazole?

Ketoconazole is an antifungal medicine used to treat systemic fungal infections. It is available as oral tablets, shampoos, and creams. Ketoconazole works by inhibiting the synthesis of lanosterol, an important component of fungal membranes. This results in fungal death and infection clearance. Due to the possibility of developing adverse effects, the physician will recommend ketoconazole after a careful risk-benefit analysis. It is used only after all first-line alternatives fail to work.

What are the uses of ketoconazole?

Ketoconazole has very limited uses as an antifungal drug. It is used only when other alternative medicine options fail.

  • Ketoconazole is used to treat systemic fungal infections like blastomycosis, histoplasmosis, paracoccidioidomycosis, coccidioidomycosis, and chromomycosis.
  • It is also used to treat skin infections like tinea versicolor, seborrheic dermatitis, jock itch, athlete? foot, excessive dandruff, and baldness.
  • The tablets are also used (off-label) to treat patients with Cushing? syndrome and manage the hirsutism (excessive hair growth) caused by hormonal imbalance.
