Topical treatment of tinea versicolor

Topical treatment includes special cleansers including some shampoos, creams, or lotions applied directly to the skin.

The shampoo is left on the skin overnight and washed off in the morning. To be effective, the shampoo treatment may be required for few nights.
Tinea versicolor usually recurs, requiring additional treatments. Your physician may also prescribe topical creams or oral antifungal medications.
It is also important to know that improvement in the skin may only be temporary, and a recurrence of the condition is possible. Your physician may also recommend using the shampoo monthly to help prevent recurrences.
The treatment will not bring the normal color back to the skin immediately. This will occur naturally and may take few months.
Treatment with a single 400-mg dose of ketaconazole is also effective.
