Comments from Expert Advisory Committee

  • Due to increasing resistance it is essential to send an MSU so culture can guide antibiotic treatment if no clinical response to first choice
  • Review after 14 days and either stop antibiotics or continue for a further 14 days if needed based on assessment of history, symptoms, clinical examination, MSU result
  • 4 week's treatment may prevent chronic infection i.e. chronic prostatitis but it is difficult to predict those at risk
  • Assess the need for sexually transmitted disease and STI testing
