i think you mean magnesium citrate not potassium. magnesium citrate is a good cathartic/laxative and should clean like a tornado so she will need to be in close proximity to a toilet for sure. don't send her to kindergarten. there are only a few wasy to clear a bowel impaction and this is one of them. cleansing enemas are another. using mineral oil may be tried. the last resort however. one that no one likes to do. would be surgery but don't worry this is not likely to come to this. hopefully she is seeing a good pediatric gastroenterologist to get to the "bottom" of this problem.
in general will a regiment of 10 oz. of potassium citrate over a 3 day period clear the bowel tract in a 5 year old. our granddaughter has been on a regiment of 17 grams of miralax and 5 grams fiber per day. on fri. her bowel tract was found to be backed-up. doctor ordered 2 1/2. oz potassium citrate fri pm sat am -pm and sun am. (total 10 liquid. oz) mon. an x-ray was done and still showed no improvement. question. if medication was given following doctors orders should blockage have corrected or at the least shown improvement?
