Indications
Nizoral Shampoo (active ingredient: ketoconazole) is a prescription medication indicated for the following:
- Dandruff: Nizoral Shampoo is used for the treatment of dandruff, a common scalp condition characterized by flaking and itching.
- Seborrheic Dermatitis: It is also indicated for the treatment of seborrheic dermatitis of the scalp, a chronic inflammatory skin condition that causes flaky scales and redness.
Nizoral Shampoo belongs to a class of drugs known as imidazole derivatives, which work by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes. This action disrupts the fungal cell membrane integrity, leading to fungal cell death and alleviating symptoms of dandruff and seborrheic dermatitis.
Uses and Dosage
Ketoconazole shampoo is used to treat fungal infections of the skin. It is typically applied once daily for 2-6 weeks as directed by your doctor. Follow your prescription label and any instructions from your doctor or pharmacist carefully. Apply the shampoo to the affected area and do not use more or less than prescribed.
The dosage of ketoconazole shampoo can vary depending on the condition being treated. For seborrheic dermatitis, ketoconazole foam should be applied to the affected area twice daily for 4 weeks, while ketoconazole cream should be applied twice daily for 4 weeks or until the condition clears. For cutaneous candidiasis, tinea corporis, tinea cruris, tinea pedis, or pityriasis versicolor, ketoconazole cream or shampoo should be applied to the affected area as prescribed by your doctor.
