Using a Smart Pen While on a Pump Break
Early T1D life
I have lived with Type 1 diabetes since I was 13 years old, diagnosed in 2000. For most of my life with T1D, I relied on multiple daily injections (MDI) to administer insulin. Throughout that time, there have been some scary moments.
There was the time I accidentally gave myself 14 units of Humalog instead of Lantus, with no glucagon in the house. With no CGM at the time, I stayed up until 6am drinking sugar water and pricking my finger, afraid of what would happen if I lost consciousness.
There have also been times when I couldn’t remember if I had taken a shot or not, and as such decided to play it safe and ended up going without insulin.
And then of course there have been times where I outright just forgot.
Starting on a pump
In 2018 I started working at Beyond Type 1, and was fortunate to be surrounded by people living with diabetes. I had been reluctant to try a pump because of the tubing and what I perceived to be an inconvenience. I didn’t know until then that there were tubeless pumps, and within 6 months I started on the Omnipod. For the most part, I loved my new pump. I no longer needed to worry about missed doses. I didn’t need to have two different kinds of insulin, since the basal was now a drip, and I could always look back and automatically see how much insulin I had taken.
Taking a break
But it wasn’t all roses. Faulty pump sites occasionally led to high blood sugars, and perhaps most frustratingly, I developed an infection that required antibiotics to treat. I was ready to take a break, but I didn’t want to have to lose some of the technological advances gained from switching to a pump. I wanted to know how much insulin I had taken without having to log it. I wanted to be reminded when it was time to take my insulin and if possible, have suggested bolus amounts. And I also wanted to know how much insulin on board (IOB) I had regardless if I was on a pump or not.
Getting a smart pen
In 2020 I took off my pump and started using the InPen. The InPen showed me my IOB, automatically logged my insulin doses, and even allowed for me to bolus in half-units. Other advantages were the bolus calculator and the automatic data uploads. There were some slight disadvantages as well, namely that I needed to get separate insulin cartridges, and that the pen only worked with rapid-acting insulin, I would still need to log my Lantus by hand. The InPen was exactly what I needed at the time to feel confident in knowing my insulin doses while getting to take a break from an insulin pump.
I have since gone back to using a pump, and am now using the Omnipod 5, a closed-loop system which connects with my CGM to automatically manage my blood sugar. I am thankful knowing that if and when I ever want to take a pump break again, there will be multiple options of connected pens and management systems for me to choose from.
