What is Kera-42?
There are many brands and forms of urea topical available and not all brands are listed on this leaflet.
Kera-42 (for the skin) is used to soften rough or dry skin caused by skin conditions such as eczema, psoriasis, keratosis, and others. This medicine is also used to soften damaged fingernails or toenails so they can be removed without surgery.
Kera-42 may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

How should I use Kera-42?
Kera-42 is available in many different forms (cream, lotion, ointment, liquid, gel, foam, shampoo, and others) for use on the skin or the scalp. Use your medicine exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Apply a thin layer of this medicine to the affected skin and rub it in as completely as possible.
When applying Kera-42 to the nails, avoid getting any medicine on the cuticles or surrounding skin. Apply generously to the nail and allow the medicine to dry. You may cover the nail with a bandage or gauze if your doctor advises. The treated nail should be easily removed after several days.
Shake the Kera-42 foam well just before each use. Other forms of this medicine may also need to be shaken before use. Follow all directions on th medicine label.
Wash your hands with soap and water after applying this medicine, unless you are treating the skin on your hands.
Call your doctor if your symptoms do not improve, or if they get worse while using Kera-42.
