Avermectin pour-on solution is a highly effective topical antiparasitic widely used in canine practice to control internal and external parasites. However, improper application can lead to treatment failure or even adverse reactions. This guide from Pevet provides a clear, safe, and practical step‑by‑step protocol for using Avermectin pour-on solution in dogs, whether you are a veterinary professional or a diligent pet owner. Always consult your veterinarian before starting any parasite control program.

Before using Pevet Avermectin pour-on solution, verify that the product is specifically formulated for dogs. Some avermectin formulations are intended for cattle or horses and may contain different concentrations or solvents that are unsafe for canines. Avermectin pour-on solution is indicated for the treatment and control of roundworms, hookworms, whipworms, and certain ectoparasites like mites and lice.
Checklist:
Read the label carefully – ensure the concentration (e.g., 0.5% or 1%) matches your dog’s weight range.
Confirm the product is registered for canine use in your country.
Always perform a faecal test or skin scraping to confirm the parasite type before dosing.
The most critical step is calculating the correct volume of Avermectin pour-on solution based on your dog’s body weight. The standard dosage is typically 0.5–1.0 mg of avermectin per kg of body weight, but always follow the specific product instructions.
How to calculate:
Weigh your dog accurately using a pet scale. (Do not guess!)
Check the concentration – e.g., if the solution is 0.5% (5 mg/mL), then for a 10 kg dog, you need 1–2 mg total, which equals 0.2–0.4 mL of the solution.
Use a syringe with a needle‑free adapter to measure the precise volume.
Important: Overdosing can cause neurological toxicity, especially in Collies, Shetland Sheepdogs, and other MDR1‑mutant breeds. For these sensitive breeds, a reduced dose or alternative therapy is recommended.
Avermectin pour-on solution is applied topically to the skin, not orally or by injection. The drug is absorbed through the sebaceous glands and spread via the skin’s natural oils, so proper site preparation is essential.
Preparation steps:
Part the hair on the dog’s back, between the shoulder blades, to expose the skin.
Ensure the skin is clean, dry, and free from dirt, grease, or moisture. Do not bathe the dog for at least 48 hours before or after application.
Have the measured dose ready in a syringe or dropper.
Pro tip from Pevet: Applying the solution at the base of the neck or between the shoulder blades prevents the dog from licking the product off, which reduces the risk of oral ingestion and ensures better systemic absorption.
Now it is time to apply the Avermectin pour-on solution. Follow these steps precisely to ensure uniform distribution and maximum efficacy.
Application procedure:
Hold the syringe or dropper close to the skin (not on the hair).
Squeeze the measured volume slowly onto one spot on the exposed skin.
For larger dogs (>20 kg), it is recommended to split the dose into two or three spots along the midline of the back (e.g., at the shoulder, mid‑back, and base of the tail) to enhance absorption.
After application, gently massage the area for a few seconds to help the solution spread, but avoid rubbing vigorously.
Keep the dog still for at least 10 minutes to allow the solution to absorb.
Do not apply the product to broken or irritated skin, as this may increase systemic uptake and cause toxicity.
After using Pevet Avermectin pour-on solution, monitor your dog for any signs of adverse reactions, especially within the first 24 hours. Common side effects are rare but may include transient salivation, lethargy, or local skin irritation. If you notice severe tremors, ataxia, or vomiting, contact your veterinarian immediately.
Additional care tips:
Do not bathe or allow your dog to swim for 48 hours after treatment.
Keep treated dogs away from water sources (ponds, streams) to protect aquatic life, as avermectin is highly toxic to fish.
Retreat as per your veterinarian’s schedule – usually every 4–6 weeks for monthly prevention.
Breed sensitivity: Do not use Avermectin pour-on solution on Collies, Old English Sheepdogs, or their crosses unless specifically advised by a vet, as they may carry the MDR1 mutation.
Not for puppies: Avoid use in puppies under 8 weeks of age unless directed by a veterinarian.
Human safety: Wear gloves when handling the solution and wash hands thoroughly after application.
Environmental caution: Dispose of unused product and packaging responsibly – do not contaminate household waste or water systems.
Store Pevet Avermectin pour-on solution in its original container, tightly sealed, at room temperature (15–25°C) away from direct sunlight and moisture. Do not freeze. Use within 24 months of manufacture or as indicated on the label. Discard any remaining solution after the expiry date.
