There is no drawback but while in your interviews during MBA selection process you can be asked the reason to shift from bsc to MBA. Though its common but they will check your style os expressing and your confidence.
You can do MBA in IT, Operations, International Business, Marketing and there are many more branches.
To apply for MBA admission exams aim at scoring minimum 50% in your graduation.
Definitely you can pursue MBA.
Good Luck.
