Thanks for contacting HCM with your medical questions. You are wondering if clobetasol is a treatment for fungal infection. Actually clobetasol is a steroid cream or ointment used for eczema. If you use the clobetasol on a fungal infection it will actually make the infection worse. For fungal infections of the feet and groin area I recommend Lamisil or Tinactin. Jock itch is a fungal infection in the groin and can use the same medication for both feet and groin. I also recommend using a powder or a spray as this helps keep the toes and groin dry and allow for better healing. Hope this answered your question. Please contact HCM again with your medical concerns and questions
