I learned on the internet hat Fresh Kote eye drops could cause swelling of the tongue. I have been using this product for several weeks. However on Sunday 24 February 2013 I used this product in the morning before going to church then on to breakfast. Shortly after breakfast I started to experience swelling of my tongue so I went to the emergency room for treatment. My tongue was extremely swelling that the attending doctor admitted me to the hospital in the afternoon. I remained there the remainder of Sunday and Sunday night and all day Monday. His reason for admitting me was because it took an unusual long period of time to reduce the swelling. Please advise if this is usual reaction to using Fresh Kote Eye Drops
