Why it matters
Correct technique ensures you get the full dose and reduces injection-site reactions.
What you can do
Take the pen out of the fridge 30 minutes early. Wash your hands, clean the skin of the thigh or belly (2 inches from the navel) with alcohol and let it dry. Remove the cap, press firmly at 90 degrees, hold until the window turns fully colored and count a few extra seconds. Rotate sites each time.
Call your care team if
You see a large spreading red patch, signs of infection or think you missed a dose.
