Uses

This medication is used to control dandruff. Use of this medication may help to relieve the flaking, scaling and itching associated with dandruff. Ketoconazole is an azole antifungal that works by preventing the growth of fungus.

Ketoconazole 2% shampoo is also used to treat a skin condition known as pityriasis (tinea versicolor), a fungal infection that causes a lightening or darkening of the skin of the neck, chest, arms, or legs.

How to Use This Medication

Wet hair and scalp completely with water. Apply enough shampoo to produce enough lather to clean hair and scalp. Massage gently over entire scalp. Rinse hair with warm water. Repeat this process if directed to do so by your doctor. Dry hair thoroughly after the final rinse.

If using the over-the-counter strength of the shampoo (1%), apply the shampoo, lather, and rinse thoroughly. Repeat this process. Dry hair thoroughly after the second rinse.

If treating skin other than the scalp, wet the skin and apply the shampoo to affected area and the surrounding healthy skin. Lather and leave in place for 5 minutes, then rinse off with water.

The dosage, number of applications, and the length of treatment depends on the strength of the shampoo (2% or 1%) and the condition being treated. Carefully follow your doctor's instructions or the package directions.

Avoid contact with the eyes. If the shampoo gets into the eyes, rinse thoroughly with water.

Do not begin using the shampoo if your scalp/skin is broken or swollen.

Tell your doctor if your condition lasts after 2 to 4 weeks of treatment or gets worse at any time.
