So I've been on birth control pills for about 2 months now. I've been very responsible taking it at the same time daily. I was on antibiotics (amoxicillin) for a week, and now I'm on my second sugar pill and I still haven't gotten my period. I'm a bit worried because I just had unprotected sex and just heard that antibiotics can interfere with the concentration of the birth control. So my question is.. Is it okay if I take Plan b?
This is from the netdoctor site, when looking up Amoxil:
'In the past, women using hormonal contraception such as the pill or patch would be advised to use an extra method of contraception (eg condoms) while taking an antibiotic like this one and for seven days after finishing the course. However, this advice has now changed. You no longer need to use an extra method of contraception with the pill, patch or vaginal ring while you take a course of antibiotics. This change in advice comes because to date there is no evidence to prove that antibiotics (other than rifampicin or rifabutin) affect these contraceptives. This is the latest guidance from the Faculty of Sexual & Reproductive Healthcare.'
Personally, I'd use extra protection, but that's just me.
