Thank you for your interesting question and I recommend that you follow up with your primary care physician
. I am glad that both you and your husband have received azithromycin to treat chlamydia. As you know, all sexual partners should received empiric antibiotic treatment when one person is diagnosed with chlamydia or gonorrhea. Partners may often be asymptomatic, and unless they receive treatment, there is a 15 to 30 percent chance of reinfecting the other individual when sexual contact is resumed. The treatment course for chlamydia is seven days, as this is the time it generally takes to eradicate the infection. The most commonly used antibiotics are doxycycline for 7 days or a single dose of azithromycin (the half life of azithromycin is approximately 5 to 7 days). So, the answer to your question is that both you and your partner should wait until 7 days after taking the single dose of azithromycin. You can thereafter resume sexual activity provided you are both symptom free (no abnormal discharge, bleeding
, or pain with urination). As an aside, because co-infection of chlamydia with gonorrhea is common, you should also be tested for this infection and empirically treated if there is high suspicion. Finally, anyone diagnosed with a sexually transmitted disease should be offered testing for HIV. I would recommend that you follow up with your primary care physician to ensure that you are up-to-date on these tests.
