title: Isolated hypomagnesemia in a patient treated with capecitabine.
abstract: Hypomagnesemia is known to occur for a variety of renal, gastrointestinal and other causes, and is often associated with other electrolyte and metabolic disturbances. We present a case of isolated hypomagnesemia in a patient who had been treated with the chemotherapy agent capecitabine. The approach to diagnosis and treatment is discussed. We postulate that capecitabine may cause isolated hypomagnesemia, possibly due to renal magnesium loss.
