My son (5 yrs old) was diagnosed with Celiac disease recently as well as eosphilinic esophagitis. The dr. put him on Prilosec to control the eosphilinic esophagitis. Does anybody have any experience with this drug? After 2 wks of taking it as well as going on a gluten free diet- he has suddenly become extremely moody and is throwing severe tantrums(which is very out of character for him). Could this medicine be causing it? And is there a need to be on it?? There isn't a lot of research out there on EOE.
