I have recently switched from Lantus to Tresiba. I used to use the ClikStar reusable pen for Lantus. In Canada Tresiba is only available in disposable FlexTouch pens. I’m finding the new pen difficult to use in the sense that the spring load is so tight that with the slightest press it injects 12 units in one go. I’m used to being able to inject at my own pace and I’d do 1 unit per second or so.
I admit I’ve had no obvious issues like bruising, it just doesn’t seem right to have what must be a very forceful jet of 12 units go in instantly. Am I concerned for nothing?
