Ivermectin Injection

Ivermectin Injection — Veterinary Antiparasitic for Labeled Livestock

Ivermectin Injection is a sterile 1% injectable parasiticide containing 10 mg ivermectin per mL. It is labeled for subcutaneous use in cattle and swine for treatment and control of specified internal and external parasites, and must not be assumed safe for horses simply because ivermectin is also used in equine oral products.dailymed.nlm.nih+1

Equine Pharma World lists this product for responsible veterinary use only. Ivermectin injection should be administered only by a licensed veterinarian or under their direct direction, using the species-specific product and route approved for that animal.

Product Overview

Ivermectin is a macrocyclic lactone antiparasitic that works by interfering with nerve and muscle function in susceptible parasites. Injectable formulations are commonly supplied as a clear, ready-to-use sterile solution containing 1% ivermectin, with each mL delivering 10 mg of active ingredient.dailymed.nlm.nih+1

The injectable product is developed specifically for cattle, swine, reindeer, and American bison in the cited U.S. labeling. It is administered subcutaneously only, under the loose skin in front of or behind the shoulder, at 200 mcg ivermectin per kg body weight.dailymed.nlm.nih+1

Important Equine Safety Notice

Ivermectin is used in horses, but the commonly approved equine products are oral pastes, gels, or liquids, not cattle-and-swine injectable solutions. FDA labeling for ivermectin liquid for horses states it is for use in horses only and warns that use in other species can cause severe adverse reactions, including fatalities in dogs.fda

Do not inject a cattle or swine ivermectin product into a horse. The formulation, excipients, approved route, dose volume, and safety profile differ from equine oral products. A horse requiring ivermectin should receive an equine-labeled product at a veterinarian-determined dose, typically 200 mcg/kg orally for labeled parasite indications.animaldrugsatfda.fda+1

Parasites Covered in Horses

When an appropriate equine ivermectin product is used, its labeled activity can include bots, large and small strongyles, pinworms, ascarids, lungworms, intestinal threadworms, stomach worms, and neck threadworm microfilariae.animaldrugsatfda.fda+1

Ivermectin does not adequately control tapeworms or encysted small strongyles. For tapeworm coverage, veterinarians may recommend an ivermectin-plus-praziquantel combination product where appropriate.merckvetmanual+1

Why Fecal Egg Count Testing Matters

Modern parasite control should be targeted rather than automatic. The Merck Veterinary Manual notes that in intensively managed horse populations, macrocyclic lactones such as ivermectin and moxidectin may not suppress strongyle egg counts for as long as previously expected.merckvetmanual

A veterinarian can use fecal egg count testing, dewormer efficacy monitoring, pasture management, and selective treatment to reduce unnecessary chemical exposure and slow resistance development. Treating every horse repeatedly with the same product without diagnostics can promote anthelmintic resistance.

Administration for Labeled Livestock

For cattle and swine, ivermectin injection is given subcutaneously at 200 mcg/kg. With a 10 mg/mL product, each mL treats approximately 50 kg (110 lb) of body weight, and the label sets a maximum of 10 mL per injection site.dailymed.nlm.nih+1

Use sterile equipment, disinfect the vial stopper and injection site, restrain the animal appropriately, and inject under the loose skin in front of or behind the shoulder. The product label specifically states subcutaneous administration only, in part to reduce the risk of potentially fatal clostridial infection at the injection site.dailymed.nlm.nih+1

Do not exceed labeled injection-site volumes, and rotate sites when multiple injections are necessary. Never administer intravenously, intramuscularly, or orally unless a veterinarian specifically directs it for an approved product and species.

Contraindications and Precautions

Do not use ivermectin injection in animals with known hypersensitivity to ivermectin or any excipient. The cited cattle-and-swine injectable label warns that the product should not be used in other animal species because severe adverse reactions, including fatalities in dogs, may result.vmd.defra.gov+1

Use caution in debilitated, dehydrated, or systemically ill animals, and seek veterinary advice before treating pregnant or lactating animals. Follow all meat and milk withdrawal periods on the specific product label and applicable local regulations.vmd.defra.gov+1

Seek veterinary care promptly if an animal develops tremors, ataxia, depression, blindness, collapse, swelling, or breathing difficulty after treatment.

Storage and Handling

Store Ivermectin Injection according to the manufacturer’s label, protected from light and temperature extremes. Keep the vial tightly closed, avoid contamination of the rubber stopper, and discard any product that is discolored, cloudy, or past its expiration date.dailymed.nlm.nih+1
