What happens if I have sex during my treatment of chlamydia


If you have sex during the time you're being treated for Chlamydia, you can pass it to your partner. If they get Chlamydia, it can be passed back to you again as well.

To be on the safe side we recommend that you do not have sex until:

- one week after your 1-day treatment; or
- your 7-day treatment is complete, and
- your sex partner(s) have also been treated, even if their test results are negative.

Chlamydia is passed between people through unprotected oral, anal or vaginal sex. The bacteria can be found in semen, vaginal fluids, and rectal fluids.

Condoms work well at preventing chlamydia, but if condoms are not used correctly for example having some genital to genital contact before putting the condom on or if someone had oral sex without a condom, it could be possible to pass chlamydia to someone else or get it back from an untreated partner. Chlamydia usually does not show any symptoms so it can be difficult to know if you have it back again unless you do another test.

If you did have sex with a condom during the 7 day period it would be best to talk about your personal situation with the person who did the test for you. In some situations they will recommend that you and your partner(s) get re-treated or they may suggest that you come back for a follow up test in 4weeks.

If I have sex 3 days after taking 4 250 tablets of Azithromycin but I redone on day 4 and do wait the full 7 days will the antibiotics still work?

Hi, thanks for your question

Yes, if you re-treated after having sex and then waited for the full 7 days, then the antibiotics will work. Just make sure that any ongoing partners that you have, have also been treated and have waited for 7 days otherwise they can pass the infection back to you.
