How often should I replace the needle on my insulin pen?

William Lee Dubois
Endocrinology Diabetes & Metabolism
The folks that make pen needles will tell you to use a fresh one each time you inject. The fact is you may or may not be able to use it again. It depends on how thick your hide is.

I can use a needle for about a week before it gets dull. I know one diabetic who can go a month. Some of my patients can only use a needle two or three times. How do you know when it is dull? When it hurts to take a shot.
