Hi. Thanks for your query. Noted the history and understood the concerns Since your child is under Pediatrician s supervision we can say it is safe to continue the medications. But since the bloating and pain in abdomen are still present it is imperative to visit your Pediatrician for clinical evaluation and X-ray of abdomen to see whether the fecoliths are still present or not. If the fecolith are present then the better option is to give saline-soap enema for proper evaluation as Miralax and dulcolax cause loose stools by irritation and pulling in water from intestines which can be very troublesome in a small child. Stop Miralax and Dulcolax till further orders. Give plenty of oral fluids and electrolyte solutions.
