Where should a tick injection be administered to a person? - in detail

The injection intended for tick‑related prophylaxis or treatment should be delivered into a muscle that provides rapid absorption and minimal risk of nerve injury. Preferred sites are the deltoid muscle of the upper arm and the gluteal region of the buttock.

  • Deltoid: suitable for volumes up to 2 mL; use a 25‑27 mm needle; insert at a 90° angle into the central, thickest part of the muscle, avoiding the acromion process.
  • Gluteus maximus (upper outer quadrant): appropriate for larger volumes; use a 38‑50 mm needle; insert at a 90° angle, staying at least 5 cm lateral to the sacral hiatus to prevent sciatic nerve contact.

When the patient is a child or has limited muscle mass, the anterolateral thigh (vastus lateralis) is acceptable. Use a 25‑38 mm needle, insert perpendicularly into the middle third of the thigh, avoiding the femoral nerve and vessels.

Before injection, verify the site is free of infection, scar tissue, or recent trauma. Clean the skin with an antiseptic, allow it to dry, and administer the medication swiftly. Observe the patient for immediate adverse reactions after delivery.
