Nizoral (Ketoconazole)

Ketoconazole, the active ingredient in Nizoral, is an azole antifungal presented as a topical formulation for skin use. It treats fungal skin infections such as tinea corporis, tinea cruris, tinea pedis, seborrheic dermatitis and pityriasis versicolor in patients of all ages when appropriate. GNH USA supplies Nizoral as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Ketoconazole acts on dermatophyte and yeast infections of the skin and scalp, providing antifungal therapy for several common conditions. - Tinea corporis: clears ring‑shaped fungal lesions on the body. - Tinea cruris: resolves itching and redness in the groin area. - Tinea pedis: treats athlete’s foot and associated scaling. - Seborrheic dermatitis: reduces flaking and inflammation of the scalp and face. - Pityriasis versicolor: eliminates discolored patches caused by Malassezia species.

Ketoconazole topical preparations may cause local skin reactions.

Common Side Effects: - Itching: mild to moderate sensation at the application site. - Burning: transient heat sensation after application. - Redness: localized erythema. - Dryness: skin becomes less moist. - Irritation: mild discomfort or stinging. - Scaling: flaking of the treated area.
