Needle replacement

Learn why you should always replace your needle for every injection

Reusing insulin needles—both pen and insulin syringe—is a poor injection practice. You should always use a new needle for every injection for several reasons.1

Sterility and your safety

Pen and insulin syringe needles are designed for single use, and should only be used once—they are no longer sterile after use.1

Lipohypertrophy (lipo) risk

Studies have found that your risk of developing lipos goes up with each needle reuse. Even using a needle just twice can put you at significant risk.1,2

Pain and bleeding

An international research study found that people who reused their needles were more likely to experience painful injections and bleeding.1
