How To Give A Subcutaneous Injection And Sites

subcutaneous injection

subcutaneous injected A subcutaneous injection,  also known as an SQ Injection is given in the fatty layer of tissue just under the skin. Syringes for Subcutaneous Injections will use smaller needles than those used for injections into the muscle. The typical Insulin or TB syringes will have a half inch or less needle length because it only needs to go slightly below the skin level. Only certain types of medications such as hcg, lipotropicsl-lysine and vitamin injections can be given subcutaneously.


Subcutaneous injections can be given straight in at a 90 degree angle, or at a 45 degree angle. You can give the shot at a 90 degree angle if 2 inches of skin can be grasped between your thumb and index finger. If only 1 inch of skin can be grasped, give the shot at a 45 degree angle.



There are many sites on the body that are safe to give Subcutaneous shots.

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.


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. 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 covered by surgery. Avoid the surrounding area 2 inches from the belly button.


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 1-2 inches of skin.


What items do I need to give a subcutaneous injection?

  • One alcohol wipe.

  • The vial containing the injectable medication.

  • The correct size needle and syringe (included in your package).



Please read the section all the way through before giving the shot. It is important to get a general idea of what you are about to do before you begin. You may read this step-by-step procedure again as you do it.

subcutaneously injectedWash your hands thoroughly with soap and dry them completely.

Open the foil covering the alcohol wipe.

Wipe the area where you plan to give the shot. Let the area dry.

Take the cover off the needle. Hold the syringe with your writing hand and pull the cover off with your other hand, like taking a cap of a pen.

If you will give the shot at a 45 degree angle, hold the syringe with your writing hand. Place the syringe between your thumb and your index and second ÿngers. The needle should be pointing upwards or downwards at the 45 degree angle you plan to use.

If you will give the shot at a 90 degree angle, hold the syringe with your writing hand. Hold the syringe under your thumb and first finger. Let the barrel of the syringe rest on your second finger. (Many people hold a pen this way when they write)

Grasp the skin with the hand not holding the syringe. Holding the syringe barrel tightly with your writing hand, use your wrist to insert the needle through the skin. Sometimes the needle goes in easily. Some people have tougher skin and a little more pressure or quickness will be required.

Once the needle is all the way in, push the plunger down slowly to inject the syringe’s contents.

Remove the needle at the same angle you put it in.

Dispose of the syringe and needle in the sharps container.

You can purchase a Sharps Container, which is a hard plastic container made especially for used syringes and needles, at your local pharmacy. If you did not purchase this container with your medication, you can use a hard plastic container with a screw-on top such as a clothing softener or hard plastic detergent bottle. Make sure you can put both the syringe and the needle into the container easily. Whatever container you choose, make sure that the needles cannot break through the sides, bottom or top. Dispose of the container after it is full.
