can you inject insulin in fingers?
No, insulin has to be injected into subcutaneous fat (the layer of fat that sits under the skin). There is not enough subcutaneous fat in the finger to inject at that site. The sites studied and approved for injection are the subcutaneous fat on the back of the upper arm, the fat around the abdomen (avoiding the belly button and 2 inches around the belly button), the fat on the outer part of the mid -thigh on each leg, and the buttock (the fatty area above where a wallet would sit). The best way to inject into the fat is to pinch up the layer before inserting the needle into the skin. If insulin is injected into the muscle rather than the fat, it will not absorb correctly. If you use a pen needle that is shorter than 5/16 of an inch, then you do not need to pinch up the fat, but you still need to inject into the sites mentioned above.
