Ketoconazole 2% soap is a medicated soap used to treat fungal skin infections. It works by damaging the outer layer of the fungus, which stops the fungus from growing and spreading. As the fungus dies, symptoms like itching, redness, and scaling improve. This makes it helpful for conditions like dandruff (seborrheic dermatitis), ringworm, athlete’s foot, jock itch, and tinea versicolor (discolored patches on the skin).  

To use this soap, wet the affected area, apply and lather the soap, leave it for a few minutes, then rinse with water. Use it regularly as advised by your doctor for the best results. Some people may feel mild irritation, dryness, or itching, which usually goes away. Avoid using it on open wounds, broken skin, or near eyes. People with allergies to ketoconazole or very sensitive skin should avoid this soap. Regular use clears infection and helps prevent it from coming back.
