Q: Oral Contraceptives And Antibiotics (macrobid)

Hello,

with all the misleading information out there, I figured I would look elsewhere for some insight. I have been on ocps for the past two years. I was prescribed the antibiotic macrobid for a uti and started taking it during the first week of my pills for five days and stopped taking it at the beginning of the second week of pills. The medication was not labeled as a kind that altered the effectiveness of ocps and my doctor did not mention it either. However, I did use a back-up method while taking the antibiotics and for two weeks afterward. Yet, when I started my withdrawal bleeding or "period" during my fourth week of placebo pills, I did not use a back-up method.

My question is: would it have been possible to ovulate during that week of placebo pills because of the prior use of antibiotics?

I'm a nervous wreck and would really like some advice!

Thank you.

No, you would have been protected during the placebo week. You also did the correct thing in using back-up like you did, so your protection would not have been compromised.

I will add this..

Some doctors believe that certain antibiotics do not interact with birth control, while others believe 'better safe than sorry'.

Adviceseeker, during you periods the chances to become pregnant are very-very low, even without any contraception.

As for macrobid, you can read about this antibiotic here: http://www.Drugs.Com/pro/ortho_micronor.Ht ml
