What is Ketoconazole Shampoo?

Ketoconazole shampoo is also prescribed for a skin condition called pityriasis Versicolor. Pityriasis Versicolor is a skin rash that is also caused by a yeast-like germ. Although small numbers of this germ commonly live on the skin and do no harm, some people are prone to it multiplying on their skin more than usual, which leads to small pale or brown patches of skin developing. In some people, hot, sunny or humid weather seems to trigger the germ to multiply on the skin.

Ketoconazole shampoo is available on prescription, and you can also buy some brands without a prescription at pharmacies and other retail outlets. It can be used by adults and children over 12 years of age.
