Patient :My partner is on Levlen for birth control but has recently been on Cephalexin antibiotic for a bladder infection. This has cleared up and she has finished the course yesterday. Does the antibiotic affect Levlen's effectiveness? And how long should we wait to be having non condom used sex again?
