Massive hemolysis following inhalation of volatile nitrites

Abstract

Volatile nitrites are drugs which have become widely used for their mood-altering and aphrodisiac effects. Their use has been associated with methemoglobinemia and mild hemolysis; more significant hemolysis has been noted in a patient with G6PD deficiency. We report here a case of massive hemolysis following inhalation of volatile nitrites in the absence of an apparent intrinsic red cell defect. It is important that health care workers are aware of side effects from these commonly abused substances.
