How to use Ovidex for ear ticks? - briefly
Apply Ovidex directly to the ear area where ticks are present, covering the entire lesion and allowing the solution to absorb for the specified duration before gently cleaning the site. Repeat the application according to the product instructions, usually every 12–24 hours, until the infestation is cleared.
How to use Ovidex for ear ticks? - in detail
Ovidex is a veterinary formulation containing ivermectin, designed for systemic control of ectoparasites such as ear ticks. Effective administration requires adherence to dosage, timing, and safety protocols.
The recommended dose for ear tick treatment is 0.2 mg kg⁻¹ body weight, delivered as a single subcutaneous injection. Calculate the animal’s weight, multiply by 0.2 mg, and draw the corresponding volume from the vial. The injection site should be the dorsal neck region, where the skin is loose and hairless. Use a sterile needle (22–25 G) and ensure the syringe is free of air bubbles before insertion.
After injection, monitor the animal for at least 30 minutes. Observe for signs of adverse reactions: excessive salivation, tremors, or respiratory distress. If any of these occur, contact a veterinarian immediately.
Efficacy against ear ticks manifests within 24–48 hours. The parasite’s life cycle is interrupted because ivermectin concentrates in the animal’s blood and lymph, reaching the feeding ticks lodged in the ear canal. Repeat treatment is unnecessary unless a new infestation is confirmed.
Key points for optimal results:
- Verify animal weight accurately; under‑dosing reduces effectiveness, overdosing increases toxicity risk.
- Inject into the recommended site to promote rapid absorption.
- Maintain a clean injection environment to prevent secondary infections.
- Record the administration date, dose, and batch number for future reference.
- Store Ovidex in a cool, dry place, away from direct sunlight; discard any vial past its expiration date.
When treating a herd or flock, stagger injections by no more than 24 hours to avoid simultaneous peak plasma concentrations, which could complicate observation of side effects. Combine Ovidex administration with routine ear cleaning to remove debris that may shield ticks from systemic exposure.
In cases of pregnant or lactating animals, consult veterinary guidance before use, as ivermectin crosses the placenta and may appear in milk. For species other than cattle, dosage adjustments may be required; refer to the product label or veterinary prescription.
