Individuals using SSRIs were more likely to experience a stroke, die, fall or fracture, have a seizure or epilepsy and have hyponatraemia in comparison to TCAs.
Drinking too much water that your kidneys can not flush out in the limited time can cause hyponatraemia in which sodium level of body are significantly reduced.
WHO is planning to monitor this very carefully by doing what we call «post-marketing» studies: in areas where the new ORS will first be introduced, they will monitor the incidence / prevalence of hyponatraemia, biochemically as well as clinically.
