J.O.
I had my son on Zantaz for a while for reflux, but it doesn't actually stop the acid from coming up, just relieves the irritation from it, not really addressing the actual cause of the reflux. My baby's reflux (and a lot of other problems) disappeared completely when we took him off dairy. My son was 99.9% breastfed too. But even that had enough of the milk protein in it to cause him trouble. In my opinion, the Zantac didn't help my son.
