Ivermectin Wormers for Horses

Shop ivermectin horse wormers containing ivermectin as the sole active ingredient. Available in oral paste and selected in-feed formulations, these products provide options for individual horses, ponies and larger equine properties.

Ivermectin is a broad-spectrum anthelmintic used to treat and control susceptible internal parasites in horses. Depending on the registered product label, coverage may include large and small strongyles, pinworm, ascarids, hairworm, stomach worms, lungworm, intestinal threadworm and bots. Always check the individual label because approved parasite claims, concentrations, dosage rates, age restrictions and pack sizes can differ between products.

Ivermectin-only wormers do not control tapeworm. If tapeworm treatment is required, a suitably registered product containing an appropriate tapeworm active will need to be selected as part of a veterinarian-guided parasite-management program.

Accurately determine the horse’s bodyweight and administer the complete calculated dose. When using an oral syringe, ensure the paste is deposited correctly and swallowed. For ivermectin products designed to be mixed with feed, supervise the horse until the entire medicated portion has been consumed. Explore our in-feed horse wormers if this administration method is preferred.

Faecal egg counts and veterinary advice can help determine whether treatment is necessary and whether ivermectin is likely to be effective on your property. Repeated reliance on the same active ingredient can contribute to resistance, so treatments should be selected according to parasite risk and professional guidance rather than automatically rotating products or worming at fixed intervals.

Follow all registered label directions, withholding periods and safety precautions. Check suitability before treating foals, pregnant or lactating mares, breeding stallions or unwell horses. Browse the complete horse wormers range to compare other active ingredients and parasite coverage.
