Azithromycin right after unprotected sex and prevention of transmission?

[paranoidzap]

Hi,
I had unprotected sex with a new partner. Afterwards, I freaked out and took 1g of Azithromycin (about 1 hour after sex). foolishly, I had unprotected sex with my girlfriend the next morning. Yesterday I took another 500mg of Azithromycin. Today, 4 days later, I feel like my urethra is red and a bit "wetter" inside. I feel a tingling sensation.

I am interested in how I should proceed. Can I wait a week, get tested, make sure I am clear, then have sex with my gf? And if I don't get anything from her, can I just assume she is fine?

When should I get tested? Will the Azithromycin interfere with the test? For how long would the Azithromycin prevent transmission from my gf to me?

Thanks. If necessary I will tell my gf. I won't have sex with her again before I get tested. No need to lecture me, I feel bad enough already.

Additional Details:
I had sex with the new partner around 2:00PM on day 0, took 1g Azithromycin at 2:45 on day 0, and had sex with my gf at 9:00AM on day 1, had sex with my gf again on day 2 in the evening, and noticed the symptoms on day 3. On day 4 I took 500mg of Azithromycin in the afternoon. It is now day 5. I don't know why my symptoms started to appear more than 24 hours after taking Azithromycin. I guess there were several hours for any bacteria to proliferate before the Azithromycin reached the tissues of my urethra. So I am worried I infected my gf on day 1 at 9:00AM with some bacterial infection. I don't really want to tell her to get tested, but I guess there is no harm in waiting less than a week and seeing if she infects me with something through sex.

Hope the details help. Any help or comments appreciated.

Hi there -

You do need to stop taking meds, because you can develop a resitance to it, and when you need it, it might not work.

Its possible you are developing a yeast infection or something from taking all the antibiotics.

The problem with you testing now is that you have taken antibiotics, and that can give you a false negative for a couple of weeks after taking it.  You are going to have to wait a couple of weeks to test if you want accurate testing.

How about you talk to the girl and say that you realize this is a conversation that should have happened before sex, but you think you should both have std testing now?  Let her know you don't want to infect her with anything you might have, and just want to be safe about it.  That way you aren't implying that she has anything, but that you just want to do the responsible thing, even if it is a bit late.

Thanks. I have asked the new partner to get tested. She has not taken any anti-biotics. If her test is negative, I can relax a bit. I guess I'll wait about two weeks after my last dose of anti-biotics to get tested. I hope my symptoms are all in my head or my relationship with my real girlfriend may be ruined.

Why would it be ruined?  Neither one of you brought up STDs before having sex, so if she had anything, and you got it, aren't you just as much at fault?

People can have stds without any signs or symptoms, which is why testing is so important.
