Started taking Tresiba 4 nights ago, not sure if a test shot is nessesary as with other insulin pens as the dosing system is internal. I do test shots but it pushes out about 6 units of insulin, seems a terrible waste! Please help

I agree with @mahola, not sure I understand the internal dosing system comnent though. Is your pen 100iu/ml or 200 iu/ml?
 
Hi, thank you for responding -yes I understand the dosing I just am concerned I'm wasting so much insulin on test shots. The internal mechanism of the flex pen is different, it's spring loaded and internal unlike other flex pens where you turn the dial and the trigger rises out of the pen....when you do a test shot before injecting instead of being able to control 2 units coming out it shoots 6 plus units out, which is either a design fault, a way of making extra money from the drugs company or maybe it's designed so test shots aren't necessary? I can't find any info online so thought I'd try here

I don't use that pen, but online info says it can deliver from 1 to 80 units, so if you're dialling up 2 units and you think it's delivering more then it sounds concerning.

Could it just be the initial air that's making the test shot look bigger than it is?
 
If you are not using the 200u version, then you could get it in standard 3ml cartridges and use them in a NovoPen 5 or NovoPen Echo
 
Just watched the online video on the Tresiba site and that confirms you do need to prime it (airshot).

If you think your pen is faulty, stop using it and speak to the pharmacist/doctor.
 
I'm guessing the OP thinks that it LOOKS LIKE it's pushing out 6 units.

The way my Tresiba pen is build (my Levemir was the same way) it shoots a very narrow stream of insulin. In comparison my Novolog/Novorapid creates more a droplet of insulin so it seems like less.
