This patient information on Diazolidinylurea is provided by John L. Meisenheimer, M.D. a board certified Dermatologist and skin care specialist based in Orlando, Florida. This information is not intended as a substitute for the medical advice or treatment of a dermatologist or other physician.

The results from your patch testing showed a positive reaction (contact allergy) to Diazolidinylurea. Your immune system reacts with its defense mechanisms with each exposure of Diazolidinylurea to your skin. It is unknown why certain individuals develop allergic sensitivities. In some it may take repeat exposures over long periods of time before an allergy develops. Once you have become sensitized (allergic) your immune system always “remembers” and you will be Diazolidinylurea sensitive. If you currently have eczema this chemical may be the cause but other factors may play a role as well. The information below will help you avoid this allergen.
