What is the recommended angle for subcutaneous injections?

For subcutaneous injections, the recommended angle of administration is typically between 45 to 90 degrees. This angle ensures that the needle reaches the subcutaneous tissue effectively, where the medication can be absorbed properly. When a nurse administers a subcutaneous injection at this angle, they are minimizing the risk of injury to underlying muscles and organs while ensuring that the medication is deposited in the correct tissue layer for optimal absorption.

While there are variations based on the patient's body mass and the specific medication being administered, a 45 to 90-degree angle is generally accepted as providing adequate access to the subcutaneous layer. Factors such as the thickness of the subcutaneous tissue may lead a practitioner to choose a more acute angle versus a more obtuse angle as appropriate.

It's important to remember that the other angles listed—particularly those on the extremes—may not be suitable for subcutaneous injections, as they could lead to complications, such as inadvertently injecting into muscle or causing undue discomfort. Therefore, using the recommended angle ensures both the effectiveness of the medication delivery and the comfort of the patient.
