Naphthalene-induced hemolysis in a black female toddler deficient in glucose-6-phosphate dehydrogenase.

Hemolysis following accidental ingestion of naphthalene in black females deficient in glucose-6-phosphate dehydrogenase (G-6-PD) has not been previously reported. A 20-month-old black female is presented and the literature reviewed. Although G-6-PD deficiency is X-linked, health care providers must be aware that hemolysis may occur in females who are deficient in G-6-PD after exposure to naphthalene.
