Containing ketoconazole as its active ingredient, Nizoral 2% is available in various forms, including shampoos and creams.

This article explores Nizoral 2%'s applications, mechanism nizoral 2% , effectiveness, and safety.
What is Nizoral 2%?
Nizoral 2% refers to a topical antifungal formulation that contains 2% ketoconazole. Ketoconazole belongs to a class of antifungals known as imidazoles. It works by interfering with the fungal cell membrane, ultimately leading to cell death. By inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, Nizoral 2% halts the growth of fungi and yeasts.
Forms and Availability
Nizoral 2% is available in the following forms:
Nizoral 2% Shampoo: Mainly used for dandruff, seborrheic dermatitis, and scalp psoriasis.
Nizoral 2% Cream: Applied directly to the skin to treat fungal infections like athlete’s foot, ringworm, and jock itch.
The 2% strength is typically prescribed by a healthcare provider, unlike the 1% version available over the counter.
Common Uses of Nizoral 2%
1. Dandruff and Seborrheic Dermatitis
One of the most common uses of Nizoral 2% shampoo is the treatment of dandruff and seborrheic dermatitis. These conditions are often caused or worsened by Malassezia, a type of yeast that naturally occurs on the scalp. Nizoral 2% effectively reduces flaking, redness, and itching by controlling fungal overgrowth.
2. Tinea Infections
Nizoral 2% cream is frequently used to treat tinea corporis (ringworm), tinea cruris (jock itch), and tinea pedis (athlete's foot). These are contagious fungal infections that thrive in warm, moist areas of the body.
3. Tinea Versicolor
This is a skin condition caused by yeast that leads to discolored patches on the skin. Nizoral 2% is highly effective in treating tinea versicolor, especially when used in shampoo form and applied to the affected area as a body wash.
4. Scalp Psoriasis (off-label use)
Though not FDA-approved for this purpose, many dermatologists recommend Nizoral 2% shampoo for scalp psoriasis, due to its anti-inflammatory and antifungal properties.
How to Use Nizoral 2%
Shampoo Application:
Wet your hair thoroughly.
Apply a small amount of Nizoral 2% shampoo to the scalp.
Massage gently and leave the shampoo on for 3–5 minutes.
Rinse thoroughly.
Frequency: Usually prescribed twice a week for 2–4 weeks. Once symptoms are controlled, maintenance use may continue weekly or biweekly.
Cream Application:
Clean and dry the affected area before application.
Apply a thin layer of Nizoral 2% cream once or twice daily.
Continue for the full duration prescribed, usually 2–4 weeks, even if symptoms improve earlier.
