Dab the cream onto the affected area, and rub it in gently until it’s no longer visible. Allow the cream to stay on your skin for about 8 hours. After that, wash the area with soap and water.

Your doctor may advise that you use this medication at bedtime each day. This helps keep a consistent amount of the drug in your body. And that can help the drug work more effectively.
