What degree is used for an intradermal injection?

• A. 90 Degrees
• B. 45 Degrees
• C. 15 Degrees
• D. 1 Inch Border

Answer: (C)

When giving an intradermal injection, the medicine is deposited just under the epidermis in the dermis, so the needle must enter very shallowly. A small-angle approach around 10 to 15 degrees keeps the needle in the dermal layer rather than going deeper. Using about 15 degrees helps form a tiny wheal or bleb, which is the telltale sign that the injection is in the correct layer. Going at a steep angle like 90 degrees would drive the needle into muscle (intramuscular), while about 45 degrees would place the needle into the subcutaneous fat. The measurement “1 inch border” isn’t a valid injective technique parameter. So the shallow, roughly 15-degree angle is the right choice for intradermal injections.
