Keflex: Cephalexin ( Keflex) can impact efficacy of oral contraceptives - so use of a back up protection is recommended (such as a condom).

Possible to get: pregnant as Cephalexin can decrease the effectiveness of the pill, Should use condoms as a backup measure if you are are on antibiotics. If you miss a period do a pregnancy test. If within 72 hours can take plan B.
