Hi. I've been taking amoxicillin for the past 10 days and just finished my prescription today. I have been on sprintec for a month and am on day 3 of the placebo pills. How long will the amoxicillin interfere with the birth control? If I have sex when I see my boyfriend in 2 weeks will I be ok? And also by how much does taking amoxicillin reduce the effectiveness of the pill? Thanks!
You cannot count on protection while you are on antibiotics or for 7 days after you stop them. You should use a condom until you''ve taken 7 active pills after you stop it, in your case. There is no actual measurement of protection when on antibiotics. It can vary.
