Extina Top Uses

This medication is used to treat a certain skin condition (seborrheic dermatitis). In this condition, it is believed that a fungus (Malassezia furfur) infects the skin, resulting in dry, flaky skin (scaling) on the scalp, face, ears, chest, or upper back. Ketoconazole is an azole antifungal drug that works by stopping the growth of fungus.

How to use Extina Top

Read the Patient Information Leaflet provided by your pharmacist before you start using ketoconazole and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

If the can is warm or the foam is runny, place the can under cool running water for a few minutes before using.

Use this medication on the skin only. Clean and thoroughly dry the area to be treated. To keep the medication from melting on your fingers, wash your hands with cold water and dry thoroughly before applying. Hold the can upright. Do not spray the medication directly on the affected area or on your hands. Instead, spray the medication into the cap of the can or some other cool, clean surface. Using your fingertips, pick up the medication and gently and thoroughly rub into the affected areas, usually 2 times daily for 4 weeks or as directed by your doctor. If treating the scalp, part your hair 1 section at a time, and apply the medication directly to the affected scalp area, not the hair.

Do not apply this medication in the eyes, nose, mouth, or inside the vagina. If you do get the medication in those areas, flush with plenty of water.

Wash your hands after applying the medication.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day.

Tell your doctor if your condition worsens or does not improve after 4 weeks of treatment.
