I must say, the pen/drug delivery unit is impressively designed. I've NEVER had to inject myself and this is super, super easy.
Is it the same or similar to an insulin pen?
I haven't the slightest!!
It's a little pen with a clear sight window. You remove the end cap and screw on the needle. It comes with 6 needles. Remove 2 safety caps on needle.
You rotate dial to prime (only necessary for first time using a new pen). Push button on end. Device is primed.
Now rotate dial to dosage until you see dosage in white sight window. Gently push needle onto body. Push trigger button until you hear click. Count to 5. Done.
Put safety cap on needle and unscrew needle to dispose.
Not sure how similar to insulin this is?
My curiosity did get the better of me and I tried to measure the needle. I got .2mm (.008") It's a tiny thing!!
