Duramectin Paste is a widely used antiparasitic treatment primarily designed for livestock but often considered for off-label uses in other animals, including dogs. With increasing curiosity and misinformation about its potential use in humans, it's crucial to explore the facts regarding duramectin, its recommended usage, dosage guidelines, ingredients, and the associated safety concerns.

🧴 What is Duramectin Paste and How Is It Used?

Duramectin is the active ingredient in Durvet Duramectin Paste 1.87%, an antiparasitic formulation used to treat internal and external parasites in animals like horses and cattle. The paste belongs to the avermectin class, a family of compounds known for targeting the nervous system of parasites, effectively paralyzing and killing them.

How It Works

Duramectin targets:

• Intestinal worms (roundworms, pinworms)
  
  
• Bots
  
  
• Mites and lice
  
  

When ingested, it binds to chloride channels in the parasite’s nerve and muscle cells, leading to paralysis and death of the parasite without harming the host animal when administered correctly.

🐶 Recommended Dosage for Dogs and Large Animals

Duramectin Paste Dosage for Dogs

While duramectin for dogs is not FDA-approved, some veterinarians may consider it for off-label use. Caution is essential due to the risk of toxicity, especially in breeds with the MDR1 gene mutation (e.g., Collies, Australian Shepherds).

General Guidelines (Off-label and Must Be Vet-Directed)

• Dosage: 0.2 mg/kg body weight
  
  
• Durvet Duramectin Paste 1.87% contains 18.7 mg/g of ivermectin
  
  
• A small pea-sized amount (approx. 0.1 g) may be used for a 50-lb dog ONLY under veterinary supervision
  
  

Warning: Miscalculating the dose can lead to neurological toxicity, seizures, coma, or death.

Duramectin Paste Dosage for Horses and Cattle

• Equine standard dose: One full syringe (6.08g) for 1,250 lbs of body weight
  
  
• Administered orally using the plunger markings to adjust for weight
