My husband and i just got treated for chlamydia, when should we be re-tested to see if it cleared up? and when can we have sex again?

Not recommended: Re-testing for is not routinely recommended unless you are pregnant or suspect someone is not taking their medication as prescribed. If needed, you can re-test 3-4 weeks (minimum of 1 week) after completing therapy. You should also eliminate any behaviors that may put you at risk for reinfection. 1 weeks abstinence during treatment is recommended to minimize reinfection risk.

7 days after either: Zithromax (azothromycin) taken as a single dose, or after srarting 7 day, twice daily dose of doxycyline. Thus abstain for 7 days, then you should both be ok.
