I was prescribed carafate after having several stomach biopsies done, and apparently fell into the small percentage who experiences an adverse effect. I also have Gerd and a history of severe throat problems. Most throat lozenges contain menthol which upsets my stomach and exacerbates my reflux. I found that glycerine drops help by coating the throat, and from the health food store- propolis lozenges (which I swear by!).
Another alternative is to take a liquid antacid like mylanta-- something aluminium or magnesium based which will coat your throat and help with the stomach acid. I've heard gargling with baking soda will help restore the natural Ph in the throat, but personally prefer a few drops of t-tree oil in water-- which helps against infection.
My Dr. told me that people with Gerd often have throat problems. Sleep propped up so that you are less likely to have stomach acid in your throat at night.
