duh nevermind, there's a whole index in the back. It's Esomeprazole, it says see omerprazole for recommendations, flipping over...He rates it L2: "Safer: Drug which has been studied in a limited number of bfing women w/out an increase in adverse effects in the infant. And/or, the evidence of a demonstrated risk which is likely to follow use of this medication in a bfing woman is remote"
It says "vitually all omeprazole ingested via milk would probably be destroyed in the stomach of the infant prior to absorption"
