Potential S.C. injection sites (indicated by the dotted areas) include the fat pads on the abdomen, upper hips, upper back, and lateral upper arms and anterior thighs.

Preferred injection sites for insulin are the arms, abdomen, thighs, and buttocks. For heparin, the preferred injection site is the lower abdominal fat pad, just below the umbilicus.

If repeated, rotate

For S.C. injections administered repeatedly, such as insulin, rotate sites. Choose one injection site in one area, move to a corresponding injection site in the next area, and so on. When returning to an area, choose a new site in that area.
