In brief: No

Even in 2012, ob/gyns are split on whether antibiotics affect birth control pills.
...Some say yes, some say no. However, the antibiotics most likely to affect birth control pill efficacy are the penicillins and the tetracyclines (doxycycline). Ceftin (cefuroxime) typically is in a class of antibiotics that will not affect your birth control pill.
