Reversible hepatotoxicity related to amphotericin B.

Hepatotoxicity is regarded as a rare side effect of amphotericin B therapy. A patient with acute myelogenous leukemia who had normal liver function was treated with amphotericin B for fungal pneumonia. While he was receiving the drug at high dosages asymptomatic elevation of the levels of alkaline phosphatase, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, lactic dehydrogenase and bilirubin was noted. The levels returned to normal when the drug was discontinued. Rechallenge with a lower dosage prompted a rapid rise in the levels, with subsequent return to normal when the medication was withdrawn.
