I know a lot of people need to avoid gluten in their diets. But last time I checked, nasal spray is not in anybody’s diet. On its website The American Diabetes Association says, “Gluten is found in wheat, rye, barley and any foods made with these grains.” There’s barley in beer. So don’t squirt beer up your nose. Probably wouldn’t be too pleasant. Even if you don’t have a gluten problem.
