Acute severe hyponatraemia secondary to polydipsia and associated herbal remedy use.
A 47-year-old woman presented with seizures secondary to euvolaemic hyponatraemia. A collateral history revealed recent increased oral fluid intake and increased use of herbal remedies including valerian root over the New Year period. There was no history of psychiatric disease to support psychogenic polydipsia. She responded to careful sodium replacement in the intensive care unit and was discharged with no neurological sequelae.
