Spots are almost gone, something replaces them

I suffered from moderate acne until I was put onto antibiotics (a tablet and cream). My skin has since cleared up but the acne has been replaced by what I believe is milia. It is not just on my face and eyelids but also on random parts of my body including my privates! I wonder if it might be the antibiotics? Although I did have a few of these white dots on my eyelids previous to that.
