What is the correct angle for subcutaneous injections?

• A. 30 degrees
• B. 60 degrees
• C. 45 degrees
• D. 90 degrees

Answer: (C)

Getting the medication into the subcutaneous fat rather than into muscle depends on using a moderate shallow angle as you insert. Subcutaneous tissue lies just beneath the skin, and the goal is to deposit the drug into that fatty layer. A middle-ground angle keeps the needle from going too deep into muscle while also ensuring you don’t stay too shallow to reach the fat. If the angle is too steep, the needle can reach muscle, changing how quickly the drug is absorbed and potentially causing more pain. If the angle is too shallow, you might end up in the skin layers or not reach the fat at all, leading to ineffective delivery. In routine practice with a typical short needle, this careful, moderate shallow angle reliably places the injection into the subcutaneous tissue.
