This is come up with several conversations lately. My mother asked because her brother-in-law is using insulin as an excuse not to do things.
So how do I take with me and how.
It depends.
First, insulin is at optimum potency at body temperature for 3-4 days. It is at optimum potency for up to 30 days at room temperature and bottle opened. It is at optimum potency if kept in the refrigator up to the expiration date. Your mileage may vary. I live in Texas, so it’s hard to find room temperature – 70-80 degrees.
So when I am running errands in the north Dallas area, I just have my pump on me. When I did multiple injections I carried either a vial and syringes, or pen and pen needles. I kept them at room temperature in a carrying case. Swapping out in whatever bag or purse I needed.
Now, I’ve lived here almost 30 years, and know where all the food is. I also know all the side streets and know that ambulance response time is less than 3 minutes.
If I venture into Dallas proper I start thinking about bring spare stuff. I know the likelihood of dropping dead with out extra insulin is low, so often don’t carry it. Do carry emergency food in the truck at least.
When I am going to be a place I don’t know well, and know I am going to be gone all day, I will take my Climapack with me. It is guaranteed to keep insulin at room temperature so I know anything in it is good for 30 days.
I cycle contents (one pen and one vial) every thirty days into my regular insulin supply with no problems.
If I am doing a driving trip, I have a cooler that is car battery powered that will keep my insulin – I use it whenever I’m going over night.
So yes, it depends.
