This upcoming Friday it will have been two weeks since i have been treated for Chlamydia with 2 500mg Azrithromycin pills that i took at one time as directed. Is there any way the treatment could have failed? Or why the treatment could have failed if it did? The infection was around 4 weeks old and i think i caught it on 3/14. I also treated a UTI with antibiotics starting on 3/21 but did not complete the whole course of antibiotics. Could those antibiotics still have been in my system and interfere with the Azrithromycin treatment i did on 4/15 for chlamydia?
