Because most cases of Non-Gonoccocal Urethritis (NGU) are undiagnosed chlamydia infections, the first line of treatment for NGU is the same as the treatment for chlamydia.
If that treatment doesn’t work, and you took all your medication as instructed, your doctors will normally check you for a Trichomoniasis infection. If that test is negative, and he can’t identify what the source of the infection is, your doctor will generally treat you with one of the drugs below. This is because some of the bacteria that cause urethritis can be difficult to identify, and these treatments are effective at eliminating the most common suspects.
Note: The drug regimens below are taken from the the Centers for Disease Control 2006 STD treatment guidelines. Remember that only your doctor can say which treatment is right for you.
Recommended Regimens for Men with NGU Where Treatment for Chlamydia Was Not Successful
Metronidazole 2 g orally in a single dose
OR
Tinidazole 2 g orally in a single dose
PLUS
Azithromycin 1 g orally in a single dose (if not used for initial treatment)
