In interviewing the patient, obtaining a detailed medication history, including information on over-the-counter (OTC) drugs the patient has been using, is important because many medications may precipitate hyponatremia (eg, antipsychotic medications, antidepressants, [15] antiepileptic drugs, [16] diuretics). A dietary history with reference to salt, protein, and water intake is useful as well. For patients who are hospitalized, reviewing the records of parenteral fluids administered is crucial.
