Treatment of Sporotrichosis

  • For cutaneous and lymphocutaneous sporotrichosis, the Infectious Diseases Society of America recommends itraconazole 200 mg once daily for 2-4 weeks after all lesions have resolved, typically totaling 3-6 months of therapy 1, 3

Monitoring and Dosing Considerations

  • The Infectious Diseases Society of America recommends measuring serum itraconazole levels after at least 2 weeks of therapy, with target trough concentrations of >0.5 mcg/mL for prophylaxis and 1-2 mcg/mL for active invasive infection 1, 3, 7
  • For doses ≥200 mg/day, the Infectious Diseases Society of America recommends dividing into two doses 6
  • The Infectious Diseases Society of America recommends considering a loading dose of 200 mg three times daily for 3 days when initiating therapy for systemic infections 6, 7

Special Populations

  • The Infectious Diseases Society of America recommends that immunocompromised patients with disseminated sporotrichosis may require lifelong suppressive therapy at 200 mg daily 1, 3
  • The Infectious Diseases Society of America recommends that pregnant women should avoid itraconazole entirely and use amphotericin B instead 1, 3
