Where is the best place to give yourself insulin shots? I'm on Humalog during the day and Levemir at bedtime, both on FlexPen. Also how close together can I take these shots?
Insulin must be given into subcutaneous fatty tissue in order to absorb correctly. The preferred sites are the fatty tissue in the back of the upper arm, the abdomen (avoiding the belly button), the area on the top, middle outer aspect of the thigh, and the top of the buttock. Of these sites none is better than the others; it really depends on what is most convenient for you and the plan you have for rotating the injection sites. For instance, if you use the thigh for your morning Humalog before breakfast, then you may want to use the back of the arm for your lunchtime dose and your abdomen for your evening dose. Some people adjust their injection sites based upon how high their blood glucose level is, using the abdomen for quickest absorption and the buttock for slowest. However, with the newer insulins, injection site choice has less effect on absorption than was the case with NPH and regular insulin. Levemir is not approved for use in the buttock area, so this site should be avoided for your Levemir dose. Concerning how far apart to give Humalog and Levemir, we recommend injecting Humalog and Levemir at least 3 inches apart.
