Pen Needle 31G 5mm Dr. Hop 100 Needles

Needle for Pen 31G 5mm Dr. Hop - Medical Device

Insulin pen needles.

The pen needle is a sterile disposable medical device , so it must be changed with each injection, because you risk not having an accurate dosage.
Leaving the needle attached to the pen between injections can alter the composition of the insulin and allow air to enter the cartridge through the needle. Air bubbles reduce the regular flow of insulin during injection, with the consequent risk of reduced drug delivery.

If you leave the needle attached, the insulin left inside the pen can turn into crystals and completely or partially clog the needle, making it difficult or impossible to inject;
Once used, in fact, the pen needle has lost its sterility.
