I have not heard of this but I notoiced it is used to treat eczema. This make sense because Vitiligo and Eczema have been known to have some simular medications that are afffective. For example Protopic is for Eczemza but I had some success with Protopic in the past.

Thank you for responding to my post. I have started to use the medication on last week and trying to remember to do my home light therapy. I am hoping this helps. I have used Opelzura for over a year and it has helped in some areas, but concern about continuing to use it with known side effects is scary.
