I am in my third day of a zithromax course, the antibiotic commonly given to cure chlamydia
a sinus infection. My boyfriend was tested for
came back positive for chlamydia (today, after I had taken 3 days worth of z-pack). I am considering being tested just to 'be safe' but know that not only will the z-pack affect the test, but will most likely have cured any chlamydia I may have had (we have not had unprotected sex).
