Default Injection Tips


One thing for sure is you didn't hit a muscle. When insulin is injected into a muscle, it works much faster than it does when you inject it under the skin:

"Intramuscular insulin injection is a technique used for both pets and people in an effort to hasten onset, compared to the usual technique of injecting subcutaneously. It's often referred to medically by the abbreviation IM.

"Because it carries with it a substantial risk of hypoglycemia, giving insulin intramuscularly should only be done with guidance from a medical professional."

There are other areas you can inject besides the scruff:

"Some veterinarians feel that the scruff is not the best place to inject because this area is prone to the formation of lumps under the skin, and because it is easier for the owner to mistakenly inject into muscle or skin. Any of these would interfere with proper insulin absorption. Other veterinarians feel that the scruff is acceptable as an injection site if the owner uses proper injection technique.

"Whichever injection sites you use, the key is to use proper pinch-up technique so that the needle goes into the fat layer below the skin - not into skin or muscle, and not through the pinch and out the other side, which just squirts insulin onto the pet's fur instead of into the pet.

"It is important to rotate injection sites, because constant use of the same spot will cause scarring, which will affect how well the insulin is absorbed."

Another reason some don't prefer using the scruff is because of the absorption from the area:

Dr. Greco:

"Is the client rotating sites?

"Is the client injecting in the proper place? (Armpit or flank instead of in the scruff; the scruff is a poorly vascularized area with slow absorption.)"

When we went to Caninsulin/Vetsulin, I switched over to the Intervet suggested areas for shots:

"Using a U-40 insulin syringe, administer the injection subcutaneously, 2 to 5 cm (3/4 to 2 in) from the dorsal midline [spine], varying from behind the scapulae [shoulder blades] to the mid-lumbar [back] region and alternating sides."

In the morning, I would give Lucky's shot on one side, and in the evening on the other. I'd also vary the injection site by working my way up and down the areas above. This made sure I wasn't giving the shots in the same place all the time.

Because Lucky wouldn't let me either do a pinch or tent on his skin, my answer about whether I could see the needle would be different.

Correct way to give an injection when "tenting" the skin. This makes sure the insulin is injected into the skin flap created by "tenting" it. When the skin "tent" is released, the injected insulin is under it, or subcutaneous.

Does this picture help?

The next picture is the wrong way to give a shot:

Wrong way to give a shot: The needle has totally passed through the "tented skin". The insulin, or any other injected drug, will be injected into the air. Note that in this graphic, the injection point is much closer to the "pinch" area holding the "tent" up. In the correct graphic, the injection point is closer to the body.
