Pharma Supply Advocate Insulin Pen Needles are manufactured to the highest quality levels possible. To deliver a more comfortable injection every Advocate pen needle is engineered using high quality surgical grade steel then tri-bevel cut for a sharper point, and electro-polished to remove microscopic burrs to give every needle a smooth finish. To ultimately result in a smoother, more comfortable and less painful injection each needle is lubricated for maximum comfort. Advocate Insulin pen needle boxes are color-coded by gauge which allows users to quickly identify correct gauge and needle length which further improves user experience and reduces confusion.

How to choose the right size insulin pen needle?

Always consult with your health care provider for recommendations on the right size pen needle.

Important Note

Pharma Supply Advocate 31G (0.25mm) 3/16in (5mm) U100 Insulin Mini Pen Needles are for single use only, do not reuse them. There is a high possibility of infection if Pen Needless are used more than once. Sharpness and lubrication also deteriorate after first use which requires more pressure to penetrate the skin thus causing pain. Do not share your needles with other people. You may give other people a serious infection, or get a serious infection from them. After injecting insulin please dispose of Pen Needless properly by using a specifically designed sharps container.
