Hypercupremia in female munitions workers using taking oral contraceptives: a case series.

Copper is an essential trace element for homeostasis and is mostly obtained through the diet. Copper can also enter the body through occupational and accidental exposure, resulting in the elevation of serum copper levels (hypercupremia). Other factors associated with hypercupremia include smoking, use of oral contraceptives, and several clinical conditions. This case series describes the presence of hypercupremia in workers exposed to copper while also taking oral contraceptives. Serum copper levels of the sample remained high, even after participants spent time away from work, normalizing only after a change in contraceptive methods. The present results underscore the importance of considering oral contraceptives as a possible cause of hypercupremia in women with occupational exposure to copper, regardless of symptomatic status.
