Sir, I am suffering from vitiligo. The first white patch got visible in 2013 and am yet to recover from these white patches. During the period of treatment, I got seriously ill. My wife's reduced to 900. After that, I stopped the treatment. Recently some new patches emerge that dragged me to have treatment once again. I consult a dermatologist who advised me to take the medicine mentioned below. 1. Tab. Tafatas 5 mg 2. Derobin (compound dithranol ointment). Is it safe? Kindly advise.
