Empiric Therapy Regimens

Empiric therapeutic regimens for urethritis are outlined below, including those for the following[1] :

  • Gonococcal and nongonococcal urethritis
  • Recurrent and persistent urethritis
  • Partners of patients with urethritis

If clinically-based diagnostic tools (eg, Gram-stain microscopy) are not available, treat patients with drug regimens effective against gonorrhea and Chlamydia, as follows:

  • Ceftriaxone 500 mg IM in a single dose (1 g in patients weighing ≥150 kg) plus 
  • Doxycycline 100 mg PO BID for 7d (contraindicated during pregnancy) or
  • Fluoroquinolones should not be used as empiric therapy because of increasing resistance of Neisseria gonorrhoeae isolates. [2]

First-line regimens:

  • Doxycycline 100 mg PO BID for 7d (contraindicated during pregnancy)
