Hello Dr. I M Suman Kaushik And I M Suffering

Hello Dr. I m suman kaushik and I m suffering from vitiligo since 2 years., I started ayurvedic treatment and it was managed but for last 4 months it is spreading fast now I have white patched almost on my whole body except face. Now I consulted with allopathic dr and he suggested me to take betnesol forte 4 tablets and pantosec 40 every Saturday and Sunday.....I m worried because I have heard that these are steroids and it causes side effects..Pls suggest me should I start this treatment.
