Table of contents:

Nizoral is a medicated drug indicated for decades to treat dandruff, seborrheic dermatitis, and other fungal scalp infections. It contains the active ingredient ketoconazole. Ketoconazole is an antifungal agent that belongs to the class of drugs called azoles. It works by inhibiting the growth of fungi and other organisms.

Nizoral is an anti-fungal medication used to treat a variety of skin and fungal infections. It is effective in treating a variety of scalp conditions, including scaling and flaking, itching, redness, and irritation. Nizoral does not just address symptoms, it gets right to the root of dandruff by controlling the fungus that causes it.

Uses and Dosage

Ketoconazole is available in tablet form and should be taken orally once a day, preferably at the same time each day. Read the directions on the prescription label carefully and follow them exactly as directed by your doctor. If you are unsure about any part of the instructions, consult your doctor or pharmacist for clarification. Do not take more or less of the medication or take it more frequently than prescribed by your doctor.

The recommended dosages of ketoconazole for adults can range from 200 to 400 mg per day orally, with the initial dose starting at 200 mg. The dose may be increased as needed, and clinical responsiveness should be monitored.
