A member asked:
I take 250mg of cephalexin daily as a suppressant for chronic utis. will this dosage of antibiotics reduce the effectiveness of my birth control?
A doctor has provided 1 answer
Probably not: Interference of antibiotics with hormonal contraception is very rare, almost an urban myth. People worry about it a lot more than necessary. But to be 100% safe, ask the doctor who prescribed the antibiotic or your birth control (or both).
