Comments
Infuse first dose over 6 hours and closely monitor for anaphylactic/adverse reactions.
May result in nephrotoxicity. Monitor renal, fluid and electrolyte (K+, Mg2+) status closely. Avoid concomitant use with other nephrotoxic drugs.
Infusion related reactions (fever, chills, nausea and vomiting) are common. Acetaminophen and/or diphenhydramine 30 minutes prior and 4 hours after infusion may alleviate febrile reactions. Meperidine may be useful for chills.
Hydrocortisone 1 mg per mg of amphotericin (Maximum: 25 mg) added to infusion bag may help prevent immediate adverse reactions.
After 1 week of therapy, adequate serum concentrations can usually be maintained by administering double the daily dose (maximum 1.5 mg/kg) every second day.
Injectable form may be nebulized. Reconstitute with 10 mL of sterile water = 5 mg/mL solution Stable for 7 days refrigerated. Protect from light *Incompatible with sodium chloride*.
