How is an injection against ticks administered? - briefly
The medication is delivered subcutaneously, typically in the shoulder region, using a pre‑filled syringe or applicator that releases the dose in a single, painless injection. Owners should follow the product’s dosing schedule and ensure the injection site is clean before administration.
How is an injection against ticks administered? - in detail
Injectable tick‑preventive agents are administered by subcutaneous or intramuscular injection, depending on the formulation and the species. The process follows a strict aseptic protocol to ensure accurate dosing and minimize complications.
- Verify product identity, expiration date, and storage conditions.
- Determine dose by animal weight; most canine products recommend 0.02 ml kg⁻¹, while bovine preparations may require 1 ml kg⁻¹ intramuscularly.
- Assemble sterile equipment: syringe (1–5 ml), needle (22‑25 G for subcutaneous, 20‑22 G for intramuscular), alcohol swab, disposable gloves, sharps container.
Perform hand hygiene and don gloves. Clean the vial’s rubber stopper with an alcohol swab, allow it to dry, then withdraw the calculated volume. Expel air bubbles by tapping the syringe and gently pushing the plunger.
Select the injection site. For dogs, the dorsal lumbar region or the space between the scapulae provides a safe subcutaneous depot; for larger animals such as cattle, the cervical or gluteal muscle is preferred for intramuscular delivery. Disinfect the skin with an alcohol swab and let it air‑dry.
Insert the needle at the appropriate angle—approximately 45° for subcutaneous, 90° for intramuscular—ensuring the tip penetrates the tissue layer without contacting bone. Administer the medication steadily, then withdraw the needle swiftly. Apply a brief, gentle pressure with a sterile gauze to the site; avoid massaging, which can alter drug dispersion.
Observe the animal for 15–30 minutes after injection. Record the date, product batch, and administered dose. Inspect the injection site for swelling, erythema, or discharge. Schedule the subsequent dose according to the product’s recommended interval, typically every 12 weeks for long‑acting formulations.
