I have a dry mouth and dry eyes. I use nasal spray because I have great difficulty breathing through my nose. I get swollen nasal passages. I was being prescribed prednisone to take down the swelling. Now, I have high blood pressure, can't have prednisone. I am not supposed to use the nasal spray but not being able to breathe makes my bp go up higher. The Afrin spray for severe congestion really helps, Thank God. I just wanted to say I was using Biotene for dry mouth until I read the ingredients. Paraben is listed in the ingredients. I had it written down in a little notebook -- paraben is cancer causing. Now, I am afraid to use it.
