Intradermal Injections

Compare patient's name and drug data against MAR. Determine expected test reaction. Check drug expiration date. Prepare correct drug dose from vial or ampule.

  1. Select injection site that is free of bruises, inflammation, edema, lesions, discoloration, and hair, preferably on forearm or upper back. If needed, use subcutaneous injection site.
  2. Extend and support elbow and forearm on flat surface, if using arm.
  3. Perform hand hygiene, and apply disposable gloves.
  4. Clean site with antiseptic swab, rotating from center outward for 5 cm (2 inches).
  5. With swab or sterile gauze between third and fourth fingers of nondominant hand, pull needle cap or sheath from needle straight off.
  6. Between thumb and forefinger of dominant hand, hold syringe with bevel of needle up. With forefinger or thumb of nondominant hand, stretch skin over site.
  7. Insert needle slowly at 5- to 15-degree angle until resistance is felt. Then advance it through epidermis to about 3 mm (1⁄8 inch) below skin surface.
  8. Inject medication slowly. If resistance is not felt, remove needle and begin again. During injection, watch for small (6-mm ) bleb to appear on skin surface.
  9. Withdraw needle while applying gauze or alcohol swab gently over site. Do not massage or apply bandage to site.
