What it is and what it is used for

for The name of your medicine is Nizoral 2% shampoo. It is called 'Nizoral Shampoo' or just 'shampoo' in this leaflet. Nizoral shampoo contains a medicine called ketoconazole. This belongs to a group of medicines called 'antifungals'. Like other shampoos, it also contains ingredients to clean your hair.

These conditions can be itchy. They are caused by a fungus (yeast) called 'Malassezia'. This fungus is found on everyone's skin, but sometimes it can overgrow and cause problems. Nizoral shampoo works by killing the fungus and stopping it from coming back.

Nizoral shampoo is used for fungal infections on the scalp and body such as:

  • Dandruff
  • Dry or greasy scaling of the scalp and other parts of the body called 'seborrhoeic dermatitis'
  • White to brown patches on the body that sometimes appear after being in the sun called 'tinea versicolor' or 'pityriasis versicolor'
