I’m an Experienced Injector
You know the routine.
Now let’s refine it.
Now let’s refine it.
You’ve been doing this for a while, so you already understand the basics.
You know what works for you. That kind of experience counts. Even so, many people discover that a few simple adjustments can make a real difference in their overall injection experience and how well their medication works.2,7 After all, even professional athletes practice every day to stay at the top of their game.
Why does injection technique matter?
Injection technique shouldn’t be something you learn once and never revisit.
Over time, habits can shift.
You might start injecting in the same area too often, using a needle longer than you need, or applying more pressure than you realize.
Studies show that people injecting insulin who refresh their technique can:
Lower their A1C4,5
Reduce the risk of pain2,7*
Reduce skin complication2,7
What’s a common injection mistake?
*Injection pain and unpleasantness have not been clearly associated with limited needle reuse.
