No: It does not.Get a more detailed answer ›
I took a 1G dose of azithromycin on Saturday & started my birth control Aviane on Sunday. Will antibiotic cause the birth control to not work?
Aviane should work: The current thinking is that except for rifampin, other commonly-used antibiotics do not alter the effectiveness of birth control pills such as Aviane. This is likely presuming a person is not sick with vomiting or diarrhea, or some other condition that decreases the absorption of a swallowed pill. One can look up: http://www. Ncbi. Nlm. Nih.

It is best to use backup method of BC along with your pill for the whole cycle during which you took the antibiotic.

However, using an additional method of BC during the current cycle will give you reassurance. ...Read more
I'm on sprintec birth control, I just finished 5 days of azithromycin will it effect it or will I need a backup for how long?
Hi. Does azithromycin affect the pill cerazette? I took 4 azithromycin 2 weeks ago and don't know how long this could impact on my birth control.
Should I take plan b if I had unprotected sex in the third week of my 7th cycle of sprintec birth control, I took azithromycin 15 days ago?
I took a one time course of Azithromycin (4 pills at once) for Chlamydia on 1/2. I began spotting on 1/13. Did pill effect my birth control?
BCP's/antibiotics: Some antibiotics can interfere with the absorption of oral bcp's, but "spotting 11 days later" is probably not related to the antibiotic taken. If you have taken a pill later than 24 hours after the last active pill, spotting can occur similar to when you take the placebo (inactive) pills. If you maintain taking the active pills no longer than 24 hours later than the last, you can minimize this. ...Read more
Took azithromycin the first week of a new pack of birth control on the third week had sex without a condom was I protected?
No: The med was likely out of your system or at such a low level it would not protect you from a reinfection. Try using condoms if your active. It will not prevent all STD's but gives you at least partial protection. I hope you understand that chlamydia can go infect your Fallopian tubes and render you functionally sterile. ...Read more
Can you take your birth control (junel fe) with azithromycin to cure (chlamydia)? Does it effect the azithromycin? Can it cause it not to work?

Should I take plan b if I had sex without a condom the third week of a new pack I took azithromycin in the first week of a new pack of birth control?
Not if on BC a while: A woman who takes birth control (BC) pills correctly, and is beyond her first pack of pills, has contraception (protection against pregnancy) every day. That means she can have sex every day, and not get pregnant. It means she has NO fertile days, as long as she takes the pills correctly. (Of course, any woman of child-bearing age, having sex, CAN get pregnant... the possibility is always there.) ...Read more
I am currently on the Depo-Provera shot for birth control. I took axithromycin for chlamydia. Can the Depo-Provera affct azithromycin frm working or vise versa?
Was prescribed Azithromycin for 10 days for a sinus infection. How does this interact with my birth control, TriNessa (norgestimate and ethinyl estradiol)? Thanks!
Should not interact: The current thinking is that except for rifampin, other commonly-used antibiotics do not alter the effectiveness of birth control pills such as TriNessa (norgestimate and ethinyl estradiol). This is likely presuming a person is not sick with vomiting or diarrhea, or some other condition that decreases the absorption of a swallowed pill. One can look up: http://www. Ncbi. Nlm. Nih.

As doctors, the first thing we do when we hear that a fertile woman is having a missed period or abnormal spotting, we check a pregnancy test. You can either take a home pregnancy test as long as it has been 5- 6 weeks since your last normal period, or you can go see your doctor and they can test you. A home pregnancy test is 97% accurate if taken a week or more after the missed period and a doctor's test can tell around when you should be getting your next period.
Since you have stopped and started your pills a few times, it makes it difficult to know if and when you could have ovulated. Definitely, anytime you stop the pill, it can cause withdrawal bleeding, but does not necessarily help predict ovulation. A pregnancy test can be accurate 3-4 weeks after you think you might have conceived so can either go by that or you should wait and see if/when you have your next period. Good luck! ...Read more
