I think it is very important for everyone to be able to handle this emergency quickly and calmly. And I also think it is important that everyone do whatever they need to do in order to be prepared.
But I want to offer a counter opinion on this.
If you have to find your phone, unlock it, find the app, and read it, you are wasting time that you don’t need to. You can see in the picture Michel posted above, the Glucagon kit has directions printed right inside the container. Those directions are always right there.
I am not sure how a phone app makes it any more clear.
The older Glucagon kit had more steps. You had to get a syringe, put air in it and inject air into the solution so there would be no vacuum when removing the solution, and then remove the solution and inject into the vial with the powder.
The new ones are more simple. And you can even simplify it further, you don’t have to remove the syringe when you are swirling the bottle around to mix it. That saves a step.
I want to point out that dosing is not crucial. There is nothing magical about 100 units. If you do 50, 72, 96, or whatever, it will start to work.
Small air bubbles are not important, they won’t cause any problem. Just inject what you get out. You can always go back in and get the remainder and inject a second time.
It works very quickly.
The time to learn how to do it is now. Not when you need it.
Let me suggest that you don’t ever throw an old Glucagon kit away. You don’t have to do something goofball and actually use a kit that expired 3 years ago. But what you can do is take your expired kit and practice with it.
Get an orange or tomato or eggplant, and go through the whole procedure and do a practice injection on the unlucky item from the produce aisle.
Be comfortable enough with it that you don’t need a phone app.
