For Healthcare Professionals

Applies to amphotericin b: compounding powder, compounding powder for reconstitution, intravenous powder for injection, oral suspension


Oral amphotericin B is not appreciably absorbed, even at high dosage, and systemic adverse effects have not been noted.

Intravenous amphotericin B will lead to some intolerance in most patients, even at less than the full therapeutic dose. Tolerance can be improved by treatment with antipyretics, antihistamines, or antiemetics. Meperidine may decrease the duration of chills and fever that accompany infusion. Small doses of IV adrenal corticosteroids just prior to or during infusion may decrease febrile reactions. Heparin and use of a pediatric scalp-vein needle may lessen thrombophlebitis incidence.[Ref]


Very common (10% or more): Renal function test abnormalities (including azotemia, hyposthenuria, renal tubular acidosis, and nephrocalcinosis), blood creatinine increased
Common (1% to 10%): Renal failure acute
Uncommon (0.1% to 1%): Renal impairment
Rare (less than 0.1%): Nephrogenic diabetes insipidus[Ref]

Renal function test abnormalities usually improve upon interruption of therapy, however some permanent impairment often occurs, especially in patients receiving large cumulative doses (over 5 grams). Concomitant diuretic use may predispose patient for renal impairment, whereas sodium repletion/supplementation may reduce nephrotoxicity occurrence.[Ref]
