Soriatane is a prescription drug for the treatment of psoriasis. There are a lot of risks involved with this medicine especially for women of childbearing years. From what I understand, it is a restricted drug for these women. My husband has EHK and has been on Soriatane for a number of years, but I do not believe it would work for all forms of ichthyosis. We also have been told there is no pill treatment for ichthyosis and in all of our research believe this to be true. So we jsut keep hoping that one day science and research will make a remarkable breakthrough and it will change the world as our family knows it!
