Treatment of uncomplicated genital Chlamydia trachomatis infections in males.

The treatment of chlamydial urethritis in males depends on the susceptibility of Chlamydia trachomatis to different antimicrobial agents. Tetracyclines seem to be the drugs of choice; long-acting tetracyclines are recommended, as these are more convenient for the patient. Both lymecycline and doxycycline produce clinical and bacteriological cure in approximately 90% of cases, when used in adequate doses. Erythromycin is the alternative treatment in patients who should not be given tetracyclines. Trimethoprim/sulfamethoxazole is effective in patients with chlamydial urethritis, but it seems to be ineffective in those with Chlamydia-negative urethritis. The importance of treating sexual partners should not be overlooked.
