ketoconazole 2% shampoo is indicated for the treatment and prophylaxis of infections in which the yeast Malassezia (previously called Pityrosporum) is involved, such as pityriasis versicolor (localized), seborrhoeic dermatitis and pityriasis capitis (dandruff).

The affected areas of the skin or the scalp should be washed with ketoconazole 2% shampoo, which should be left on the skin/scalp for 3 to 5 minutes before rinsing.

Treatment:

• Pityriasis versicolor: Once daily for 5 days.
• Seborrhoeic dermatitis and pityriasis capitis: Twice weekly for 2 to 4 weeks.

Prophylaxis:

• Pityriasis versicolor: Once daily for 3 days during a single treatment course before the summer.
• Seborrhoeic dermatitis and pityriasis capitis: Once every 1 or 2 weeks

Contraindicated in patients with known hypersensitivity to ketoconazole.

Topical treatment with ketoconazole shampoo 2% is generally well tolerated. As with other shampoos, a local burning sensation, itching or contact dermatitis (due to irritation or allergy) may occur on exposed areas. Oily and dry hair have been reported rarely with the use of ketoconazole shampoo 2%.

Overdose Effects

Not expected as ketoconazole shampoo 2% is intended for external use only. In the event of accidental ingestion, only supportive measures should be carried out. To avoid aspiration, emesis or gastric lavage should not be performed.

In patients who have been on prolonged treatment with topical corticosteroids, it is recommended that the steroid therapy be gradually withdrawn over a period of 2 to 3 weeks, while using ketoconazole shampoo 2%, to prevent any potential rebound effect. Increased hair shedding is often associated with seborrhoeic dermatitis and dandruff, and has been rarely reported with the use of ketoconazole shampoo 2%. Avoid contact with the eyes. If the shampoo should get into the eyes, they should be bathed with water.

Pregnancy & Lactation

Since ketoconazole is not absorbed through the skin after topical application, pregnancy and lactation are not a contraindication for the use of ketoconazole shampoo 2%.
