My son is 10weeks old for 2weks dr had him on Zantac for his acid reflux although it helped with his reflux he broke out in a terrible rash all over his face back and chest and got constipated; dr said to stop Zantac and wait 3days for it to get out of his system and for rash to clear up; rash is all gone and now my baby has his regular bm; but now is suffering from reflux again dr wants to give nexium has anyone tried it and if so any side effects; I just don't want to go through what we did with the Zantac it was awful
