How to give an injection after a tick bite? - briefly
Clean the bite site with antiseptic, then use a sterile syringe to inject the prescribed medication (e.g., tetanus toxoid or prophylactic antibiotic) into the appropriate muscle following standard aseptic technique.
How to give an injection after a tick bite? - in detail
When a tick attachment has been removed, the decision to administer a medication depends on the tick species, duration of attachment, and the patient’s immunization status. Common indications include prophylactic antibiotics for Lyme disease, tetanus booster, or rabies post‑exposure therapy.
Preparation
- Verify the specific drug, dosage, and route recommended by clinical guidelines.
- Assemble sterile syringe, appropriate needle (22‑25 G for intramuscular, 25‑27 G for subcutaneous), alcohol swabs, and a sharps container.
- Perform hand hygiene with soap and water or an alcohol‑based rub, then don gloves.
Site selection
- For intramuscular delivery, choose the deltoid (adult) or vastus lateralis (child) muscle, avoiding areas with bruising or inflammation.
- For subcutaneous administration, select the upper outer arm or abdomen, away from the previous bite site.
Technique
- Clean the injection area with a 70 % isopropyl alcohol pad; allow it to dry.
- Pinch the skin (subcutaneous) or stretch the muscle (intramuscular) to create a firm surface.
- Insert the needle at a 90° angle for intramuscular, 45°‑90° for subcutaneous, ensuring the bevel faces upward.
- Aspirate for 5–10 seconds only when administering blood‑borne medications; otherwise, proceed.
- Inject the medication steadily, completing delivery within 5–10 seconds for intramuscular, slower for subcutaneous solutions.
- Withdraw the needle swiftly, apply gentle pressure with a sterile gauze, and cover with a small adhesive bandage if needed.
Post‑injection care
- Observe the patient for at least 15 minutes for signs of anaphylaxis or local adverse reactions.
- Document the drug name, dose, route, site, time, and any immediate response.
- Advise the patient to monitor the bite area for expanding erythema, fever, or neurological symptoms and to seek medical attention if they develop.
Safety considerations
- Ensure tetanus immunization is up to date; administer a booster if the last dose exceeds 10 years (or 5 years for dirty wounds).
- For suspected Lyme disease, a single dose of doxycycline (200 mg for adults, 4.4 mg/kg for children) may be prescribed within 72 hours of tick removal.
- Rabies prophylaxis follows the recommended schedule of four vaccine doses, beginning as soon as possible after exposure.
Following these steps provides a systematic, evidence‑based approach to delivering injections after a tick bite, minimizing infection risk and ensuring appropriate therapeutic coverage.
