Where can I give a subcutaneous shot?
There are many sites on the body that are safe to give subcutaneous shots. Following is a list of the sites where subcutaneous shots may be given:
Upper Arm: Uncover the arm to the shoulder to see the whole arm. Have the person getting the shot stand with hand on hip. Stand next to and a little behind the person. Find the area in the middle part of the arm, halfway between the elbow and shoulder. Gently grasp the skin at the back of the arm between your thumb and first 2 fingers. You should have 1-2 inches of skin.
Abdomen: Uncover the abdomen to see the whole area. Find the waist area. You may give a shot bounded by these landmarks: below the waist, to just above the hip bone, and from where the body curves at the side to about 2 inches from the middle of the abdomen. Avoid the bellybutton. Use the natural line in the middle of the body as a marker. It may be hard to see, but it is there unless it was removed by surgery.
Thigh: Uncover the entire leg. Find the area between the knee and hip. The middle of the thigh, from mid-front to mid-side, on the outside part of the thigh is a safe site. Gently grasp the area to make sure you can pinch one to two inches of skin[ ATTACH=CONFIG]1652[/ATTACH]
Lower back: Uncover the back from the waist to the top of the rear-end. A shot may be given just below the waist to a line that runs across the back above the crack between rear end cheeks. Give the shot between the area where the body curves at the hip and a few inches from the spine.
