I always went through a dermatologist...as skin care is their specialty.
I won't swear to it, but if I remember right, all the anti-biotics I had to take, EXCEPT Eurythromycin, had special instructions regarding food. I think some of it had to be an empty stomach, and the others you had to avoid dairy around the time you took it.
The Eurythromycin explicitly wanted you to take it with food, which supposedly helped with the stomach pains. I found that taking it with nothing but a big cup of coffee worked best for me.
