It was a bit daunting at first. I just reread the directions. The most important thing is to let it warm up to room temperature before releasing the fluid into the powder. Shake it very, very well and then let it rest for the prescribed amount of time. Once that's done, injecting goes in pretty easily. I find it less uncomfortable than when I was taking Dupixent.

How are the side effects? Thoughts???

Yes, following the instructions, leaving out of fridge to get to room temp (mine is 30-40 minutes) make sure you watch for the murkiness, that it does the mixture probably, and shake as it shows, then wait, check the window, good to go!
I was a little befuddled at first. Then it's just going thru it each month.
The painless injection compared to dupixent is the added plus, for me.

Arnie,thank you for your explaining the process. It provided me with more information for my next appointment with the dermatologist.

In terms of what? Painful injection? Pen not delivering correctly? Please explain.
