What is the recommended injection angle for subcutaneous insulin?

The recommended injection angle for subcutaneous insulin is indeed 45 to 90 degrees. This range is chosen because it allows for effective delivery of insulin into the subcutaneous tissue, where it is absorbed into the bloodstream.

Injecting at a 45-degree angle is particularly useful for individuals with less subcutaneous fat, as it helps ensure that the needle reaches the intended tissue layer without penetrating too deeply. A 90-degree angle is appropriate for most situations, particularly for those with a sufficient layer of subcutaneous fat, facilitating proper absorption of insulin.

The effectiveness of insulin delivery is contingent upon the angle of administration. This ensures that the medication is not injected into the muscle tissue, which could lead to a faster absorption rate than would be ideal for sustained blood glucose control. Therefore, using an injection angle within the recommended range helps in providing optimal therapeutic outcomes.
