If you do MBA after MBBS then your salary aspect will not increase but will be the same as that of the MBA students who are being from different fields. So if you wish to go for MBA then you can obviously go for it without any doubt but your MBBS will not influence your professional career in any way with respect to the salary. The salary range you can expect may be in the range of Rs. 8-25LPA depending on the company you are placed as well as the specialization.
