Abstract

Several intestinal secretagogues became available for the patients with irritable bowel syndrome. We report a case of symptomatic hyponatremia after lubiprostone ingestion. A male patient was visiting our office to manage chronic kidney disease. He suffered chronic hepatitis (type C), which was successfully treated with asunaprevir and daclatasvir. He took lubiprostone due to constipation, and then watery diarrhoea was frequently developed. Next morning, he came to our hospital due to consciousness disturbance. Physical examination showed dehydration and laboratory data exhibited hyponatremia (110 mEq/L). Subsequent treatment against hypovolemic hyponatremia recovered his consciousness without any sequels. This case suggests that intestinal secretagogues can accompany severe electrolyte disturbance. Potential mechanisms for hyponatremia were discussed.
