So if doxy is the only treatment you have had, you should now be treated with azithromycin (1.0 g, single
dose) and tinidazole (Tindamax, 2.0 g single
dose) (or metronidazole, but it's probably less reliable than tinidazole). If these have been tried, discuss moxifloxacin with your urologist or other doctor. Also, it would be wise for both your partners to be treated similarly, if that hasn't been done.
