Nizoral cream is a topical antifungal medication indicated for the treatment of superficial fungal infections. This article provides an overview of its uses, dosage, potential side effects, and precautions for safe application.
1. Uses of Nizoral Cream 10g
Nizoral cream is a topical antifungal medication containing Ketoconazole 2% (each gram of cream contains 20 mg of ketoconazole). It is available in 10g and 5g formulations.
Ketoconazole is a synthetic imidazole dioxolane derivative with fungicidal or fungistatic activity. At lower concentrations, it inhibits fungal growth, whereas at higher doses, it eliminates fungal cells. Its mechanism of action involves inhibiting ergosterol biosynthesis, which alters the lipid composition of the fungal cell membrane, ultimately preventing fungal proliferation.
Nizoral cream 10g is used in the following conditions:
- Topical treatment of fungal infections: Applied externally for fungal infections of the body, groin, hands, and feet caused by Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum canis, and Epidermophyton floccosum.
- Treatment of cutaneous candidiasis and pityriasis versicolor (tinea versicolor).
- Management of seborrheic dermatitis, a skin disorder associated with Malassezia furfur overgrowth.
2. Dosage and Administration
How to apply: Before application, cleanse and dry the affected area. Apply a thin layer of the antifungal cream to the infected skin and the surrounding areas, then wash hands thoroughly to prevent spreading the infection to other body parts or other individuals.
Dosage for Adults:
- Fungal infections of the body, groin, hands, and pityriasis versicolor: Apply once daily to the affected area and surrounding skin. The usual treatment duration is 3 to 4 weeks for body infections and 2 to 3 weeks for groin, hand, and pityriasis versicolor infections.
- Tinea pedis (athlete’s foot): Apply once a day to the fungal infection area and surrounding skin areas for 4 to 6 weeks, or apply twice a day for 1 week.
- Seborrheic dermatitis: Apply once or twice daily to the affected area, depending on the severity. The typical treatment duration is 2 to 4 weeks, with maintenance therapy once or twice weekly.
Treatment should continue for a few days after symptoms have completely resolved to prevent recurrence.

- Do not use it in individuals with a known hypersensitivity to any ingredient in Nizoral cream.
