Yes it does: Ceflex is a broad spectrum antibiotic and it may reduce the efficacy of combined estrogen and progesterone Birth Control pills,by impairing the bacterial flora responsible for recycling of estrogen(estradiol)in large intestine. FDA advice when taking ceflex and BCP is to use additional contraceptive precaution like condom and spermicide during and 7 days after taking the antibiotic ceflex

Actually not, and no longer the official advice of expert agencies. See https://www.drugs.com/article/antibiotics-and-birth-control.html

No risk, no worry: It used to be common advice that antibiotics can interfere with hormonal contraceptives. It was always theoretical with little actual proof, and current evidence indicates no such problem except sometimes with rifampin, an uncommonly used antibiotic.
