The Dr had said daily miralax, but after the first dose, he had the blood in stool...it could have been bc he was backed up anyway. I’ve never heard of uceris foam. Will look into that in case it’s needed. Like your son, mine also has not had diarrhea, but looks like the meds are giving him constipation? I gave him a stool softener this morning and he had a bm without blood about half an hour later. I’m just documenting everything to see what works and what doesn’t. You said your son is on daily miralax...is it because of the medication or lack of fiber in his diet?
