My husband has had diabetes since he was 1 year old. He is now 34 and his sugar can get dangerously low very fast. I have had to administer glucose to him at night while he was sleeping many times while he was unconscious and unresponsive due to extremely low sugar. Other glucose tubes are hard to open and squeeze out, especially since his lips or teeth would clamp shut as a result of low sugar. This tube was very easy to administer and delivered 3 shots of regular tubes, with 45 mg instead of just 15 mg of glucose, and helped stabilize his sugar to the point that he could wake up and test his sugar and get a snack. Without this I have had to call the ambulance a couple times but now I have peace knowing that I can stabilize him myself without waiting for an ambulance.
