General reactions such as fever and chills/rigors have been reported in 35% of patients. These symptoms usually begin within 1 to 3 hours of initiation of an amphotericin B cholesteryl sulfate infusion and diminish with subsequent infusions. Slowing the rate of infusion may control symptoms. Severe infusion-related side effects associated with conventional amphotericin B administration have been lessened by pretreatment/treatment with corticosteroids, acetaminophen, antihistamines, and meperidine.[Ref]


Renal toxicity has been reported less frequently with amphotericin B cholesteryl sulfate than with conventional amphotericin B. Increased serum creatinine, BUN, and hypokalemia have occurred in patients receiving amphotericin B cholesteryl sulfate. Acute kidney failure, abnormal renal function including oliguria, albuminuria, dysuria, glycosuria, and urinary incontinence and retention have been reported.[Ref]


Metabolic changes have occurred less frequently with amphotericin B cholesteryl sulfate than with conventional amphotericin B. Decreased serum concentrations of potassium, magnesium, sodium, and calcium often accompany amphotericin-induced nephrotoxicity and patients may require replacement therapy.
