How can i treat tinea versicolor from the inside, without creams or shampoos?

Tinea versicolor: Oral antifungal can be used including ketoconazole or Fluconazole 400 mg in a single dose, or ketoconazole 200 mg daily for 7 days, or itraconazole 400 mg daily for 3–7 days. The single-dose regimens can be made more effective by exercising 1–2 hours after the dose, to induce sweating, which is allowed to evaporate, and showering is delayed for a day, leaving a film of the medication on the skin.

Nizoral (ketoconazole): Antifungal medication known as Nizoral or ketoconazole can be taken by mouth to clear t. Versicolor. It works well.
