Nizoral (Ketoconazole)

Ketoconazole blocks the fungal enzyme 14α‑demethylase, a cytochrome P450 isoform required for converting lanosterol to ergosterol. Without ergosterol, the fungal cell membrane becomes defective, inhibiting growth and leading to cell death of susceptible dermatophytes and yeasts.

The specific dosing regimen for Nizoral is determined by the prescribing clinician based on the infection type, severity, patient age, and skin condition. Typically, a thin layer is applied to the affected area once or twice daily as directed on the product label.

Safety of topical ketoconazole in pregnancy or lactation has not been definitively established. It should be used only if the potential benefit justifies any possible risk to the fetus or infant, and always under the guidance of a qualified healthcare professional.

To request Nizoral, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Nizoral belongs to the azole class and offers broad‑spectrum activity against dermatophytes and yeasts. Compared with allylamine creams such as terbinafine, ketoconazole may be preferred for seborrheic dermatitis and dandruff, while terbinafine often shows faster clearance of dermatophyte infections. Choice depends on the specific indication and patient tolerance.

Store Nizoral at room temperature, ideally below 25 °C. Keep the product in its original packaging, protect it from moisture, excessive heat and direct sunlight to maintain stability and potency throughout its shelf life.

Clean and gently dry the affected skin area before use. Apply a thin, even layer of Nizoral to the lesion and a small margin of surrounding skin. Wash hands after application and avoid covering the treated area with occlusive dressings unless directed by a clinician.

Although rare, serious adverse reactions can include severe allergic responses such as anaphylaxis, Stevens‑Johnson syndrome, toxic epidermal necrolysis, and extensive contact urticaria. Immediate medical attention is required if signs of a severe skin reaction or systemic allergy develop.

Individuals with a known hypersensitivity to ketoconazole or any component of the formulation should avoid Nizoral. It is also contraindicated on extensive broken or inflamed skin, and caution is advised in patients with liver disease when systemic absorption is possible.
