PRESCRIPTION DRUG
NIZORAL® (ketoconazole) 2% Shampoo is indicated for the treatment of tinea (pityriasis) versicolor caused by or presumed to be caused by Pityrosporum orbiculare (also known as Malassezia furfur or M. orbiculare ). Note: Tinea (pityriasis) versicolor may give rise to hyperpigmented or hypopigmented patches on the trunk which may extend to the neck, arms and upper thighs. Treatment of the infection may not immediately result in normalization of pigment to the affected sites. Normalization of pigment following successful therapy is variable and may take months, depending on individual skin type and incidental sun exposure. Although tinea versicolor is not contagious, it may recur because the organism that causes the disease is part of the normal skin flora. NIZORAL® (ketoconazole) 2% Shampoo is contraindicated in persons who have known hypersensitivity to the active ingredient or excipients of this formulation.
NIZORAL® (ketoconazole) 2% Shampoo is a red-orange liquid supplied in a 4-fluid ounce (120 mL) nonbreakable plastic bottle (NDC 50458-680-08). Storage conditions: Store at a temperature not above 25°C (77°F). Protect from light. Keep out of reach of children

This commensal organism is part of the normal skin flora. In susceptible individuals the condition is often recurrent and may give rise to hyperpigmented or hypopigmented patches on the trunk which may extend to the neck, arms and upper thighs. Treatment of the infection may not immediately result in restoration of pigment to the affected sites. Normalization of pigment following successful therapy is variable and may take months, depending on individual skin type and incidental skin exposure. The rate of recurrence of infection is variable. NIZORAL (ketoconazole) was not detected in plasma in 39 patients who shampooed 4–10 times per week for 6 months, or in 33 patients who shampooed 2–3 times per week for 3–26 months (mean: 16 months). An exaggerated use washing test on the sensitive antecubital skin of 10 subjects twice daily for five consecutive days showed that the irritancy potential of ketoconazole 2% shampoo was significantly less than that of 2.5% selenium sulfide shampoo.
