Eczema, aka atopic dermatitis, is usually caused by allergies. Often eczema sufferers are also asthmatic. Fortunately, there more medications on the market now to help control it. We have had great success with topical prescription skin medications like Protopic and Elidel, in combination with allergy shots and an asthma medication called Xolair. Relief can also be obtained after having allergy testing and eliminating known allergens from the diet/environment. Be sure the allergist is board certified, and if the patient is a child, that the allergist is certified to treat pediatric patients. For anyone living in the peidmont section of North Carolina, I highly recommend Hickory Allergy & Asthma Clinic. The doctor and his staff have helped us tremendously over the years.
