General

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]

Renal

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]

Metabolic

Very common (10% or more): Hypokalemia

Common (1% to 10%): Hypomagnesemia, decreased appetite

Rare (less than 0.1%): Hyperkalemia

Frequency not reported: Hypocalcemia^[Ref]

Common (1% to 10%): Mild gastrointestinal distress, nausea, vomiting, diarrhea

Uncommon (0.1% to 1%): Abdominal pain upper

Rare (less than 0.1%): Dyspepsia, hemorrhagic gastroenteritis, melena

Frequency not reported: Transient yellowing of the teeth (oral route), cramping, epigastric pain^[Ref]

Hematologic

Common (1% to 10%): Anemia

Uncommon (0.1% to 1%): Agranulocytosis, leukopenia, thrombocytopenia

These have included hypotension, tachypnea, cardiac arrest, shock, cardiac failure, pulmonary edema, arrhythmia, including ventricular fibrillation, dyspnea, hypertension, and transient asystole. Thrombophlebitis has occurred in many patients because of the long duration of intravenous therapy usually required.^[Ref]

Musculoskeletal
