Persistent ngu: Oral tetracyclines and erythromycin are well established choices of treatment. Despite adequate treatment, about 30-35% of NGU persist or recur. The cause of persistence or recurrence remains unknown. Prostate gland involvement has to be ruled out where indicated. A 4 to 6 week course of tetracyclines or erythromycin is suggested for persistent or recurrent NGU. See a urologist.
