WHY is this medicine prescribed?

HOW should this medicine be used?

Doxepin comes as a cream to apply to the skin. It is usually applied four times a day, at least 3 to 4 hours apart, for up to 8 days. Use doxepin at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use doxepin topical exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

To use the cream, follow these steps:

• Wash the affected skin with water and a mild soap or soapless cleansing lotion and pat dry with a soft towel.
• Apply a thin layer of cream to the affected skin. Gently and thoroughly massage it into the skin. Be careful not to get the medication in your eyes or mouth. If you do get doxepin in your eyes, wash with plenty of water and call your doctor if your eyes are irritated.
• Do not cover the affected area with any bandages, dressings, or wrappings.
