Nizoral (Ketoconazole)

Ketoconazole blocks the fungal enzyme lanosterol 14α‑demethylase, which is essential for producing ergosterol, a key component of fungal cell membranes. Without ergosterol, the cell membrane becomes defective, leading to fungal cell death and a reduction in infection.

The specific dosage and frequency of Nizoral are determined by the prescribing healthcare professional based on the type and severity of the infection, the patient’s age, and other clinical factors. Patients should follow the prescriber’s instructions and the product label.

Safety data for topical ketoconazole in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss potential risks and benefits with their healthcare provider before using Nizoral.

To order 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 (including any cold‑chain requirements), and necessary import documentation.

Nizoral’s active ingredient, ketoconazole, belongs to the imidazole class and offers broad‑spectrum activity against dermatophytes and yeasts. Compared with allylamine agents such as terbinafine, ketoconazole may be preferred for scalp conditions like seborrheic dermatitis, while terbinafine is often chosen for nail infections. Choice depends on infection type, patient tolerance, and physician preference.

Store Nizoral at room temperature, below 25 °C. Keep the product in its original packaging, protect it from moisture and direct sunlight, and ensure the container is tightly closed to maintain stability.

Apply a thin layer of the cream or lotion to the affected skin area once or twice daily, as directed by the prescriber. Gently rub it in until fully absorbed, and wash hands after application unless the hands are being treated.

Serious risks, though rare, include severe allergic reactions such as angioedema, Stevens‑Johnson syndrome, toxic epidermal necrolysis, and systemic toxicity like hepatic injury if significant absorption occurs. Patients should seek immediate medical attention if they notice extensive rash, blistering, swelling, or signs of liver dysfunction.

Nizoral should not be used by individuals with known hypersensitivity to ketoconazole or any other component of the formulation. It is also contraindicated on severely damaged or inflamed skin, and caution is advised for patients with pre‑existing liver disease or those taking interacting systemic medications.
