I took a 500mg zithromax pill at 1am yesterday and had unprotected sex with my partner who has chlamydia also and took another pill midnight and one a?

Chlamydia treatment: Proper treatment for chlamydia is 1 gram (1000 mg) azithromycin (Zithromax) in a single dose; you should have taken both pills at once. And you should not be having sex with an untreated partner! Probably all will be OK, but to be most safe I would advise that you ask your doctor for another 500 mg pill and take 2 at once; make sure your partner is treated; and no sex for at least a week.
