What antibiotics affect birth control pills?
Although the degrees to which antibiotics may affect hormonal birth control vary, there are certain antibiotics which doctors say can cause decreased effectiveness. Antibiotics that are listed as interfering include:
- Rifampin
- Penicillin
- Amoxicillin
- Sulfonamide
- Ampicillin
- Cotrimoxazole
- Tetracycline
- Griseofulvin
- Minocycline
- Phenobarbitol
- Metronidazole
- Nitrofurantoin
If you are taking any of these antibiotics while using birth control pills your doctor should recommend that you use a back-up method of birth control (ie. condom). Despite the fact there is little evidence supporting a massive increase in pregnancies with antibiotic use, it is better to be safe than sorry. Use the back-up method during the run of your antibiotic and continue for one week afterwards.
Speak with your doctor if you have any concerns or questions about antibiotics and the effectiveness of your birth control.

Hi. I am taking a medium dose of birth control and I am also taking an anti-depressant. I went to see a gyn. initially when I was put on the pill. The reason was for irregular mentrual cycles, and I did not say that I was planning on being sexually active in the near future (the doctor did not raise to dosage of the pill to be effective with the presence of the anti-depressant).
However, if I were to become sexually active, and I used the pill (at the medium dosage, not raised) and a condom, how safe am I? Would pulling out in addition to those two methods help?
Also, how long does it take for the pill to take effect from the first day you start taking it?
Thanks a lot!
Just want to double check...does Cipro interfere with Alesse?
Some antibiotics have been studied and shown not to affect the metabolism of OCPs. Ciprofloxcin (Cipro ®) is one that does not seem to alter metabolism (6). *** source: http://www.wdxcyber.com/ncontr10.htm ***
If you are at all uneasy about taking Cipro at the same time as your birth control pills you can always use a condom and spermicide for extra protection.
