thanks for writing to health care magic.Vitiligo
is a real challenge for any dermatologist to treat.
It has many associated causes one of it is autoimmune.
Betnisol and azoran works well only in autoimmune disease
.Both drugs have a large spectrum of side effects and it is not advisable to take drugs life long.
It is also recommended to take only under the guidance of a dermatologist.
You can try more safer topical options like steroid
creams and tacrolimus.
Now a days many surgical options also available for vitiligo.You need to consult a dermatologist
I hope this can solve your query.Take care.
