In brief: Yes, it depends

First of all, it depends on the birth control method you are using.
In the case of oral contraceptives (ocp's) some antibiotics (azithromycin, ciprofloxacin) can increase ocp metabolism and therefore reduce their levels in the blood, increasing chances of ocp failure. You should always ask your doctor or pharmacist about all the medications you are taking before taking anything new.
