Side Effects of Liposomal Amphotericin B

Introduction to Side Effects

  • The Infectious Diseases Society of America recommends that liposomal amphotericin B is substantially better tolerated than conventional amphotericin B deoxycholate, with significantly reduced nephrotoxicity and fewer infusion-related reactions, though these adverse events still occur and require monitoring 1, 2
  • Acute infusion-related reactions occur in approximately 20% of patients receiving liposomal amphotericin B, which is significantly lower than the 44-54% seen with conventional amphotericin B, according to the Centers for Disease Control and Prevention 3, 4, 5
  • The American College of Physicians notes that severe acute reactions can include chest pain, dyspnea, hypoxia, severe abdominal/flank/leg pain, flushing, and urticaria 3, 4, 5
  • Premedication with diphenhydramine can reduce the incidence of infusion-related reactions, as suggested by the Centers for Disease Control and Prevention 3, 4, 5

Nephrotoxicity

  • Nephrotoxicity occurs in patients receiving liposomal amphotericin B, manifesting as electrolyte abnormalities, particularly hypokalemia and hypomagnesemia, according to the European Society of Clinical Microbiology and Infectious Diseases 1, 2, 9
  • The National Institutes of Health recommends baseline and frequent serum chemistry monitoring, including creatinine, BUN, potassium, and magnesium, to prevent and monitor nephrotoxicity 1, 2, 10

Hematologic Effects

  • Anemia can occur with liposomal amphotericin B therapy, though less frequently than with conventional formulations, according to the Infectious Diseases Society of America 1, 2
  • Regular CBC monitoring is recommended by the American College of Physicians to detect hematologic effects 1, 2, 10

Hepatotoxicity

  • Elevated aminotransferase levels may occur, and regular liver function monitoring is advised by the European Association for the Study of the Liver 10

Special Populations

  • The FDA recommends that liposomal amphotericin B is considered probably compatible during pregnancy and breastfeeding, though interruption of breastfeeding may be prudent, as noted by the Infectious Diseases Society of America 1, 2

Critical Monitoring Requirements

  • Baseline and ongoing laboratory monitoring must include serum chemistry, complete blood count, liver function tests, and urinalysis, as recommended by the National Institutes of Health 1, 2, 10
