In brief: Yes

Many medications, including many antibiotics and estrogen containing birth control pills, are metabolized in the liver. The end result can be that the liver increases its metabolism of the birth control pills, thereby decreasing their effectiveness.
For this reason, many doctors recommend that you use an alternate method of birth control such as condoms while taking any antibiotics.
