Multiple dose bottle: 15 mL syringe Use a calibrated dosing syringe inserted into the bottle to measure the appropriate dose. Use a clean syringe when accessing the bottle to avoid contaminating the remaining product.

Single dose syringe: Each marking on the syringe plunger will deliver sufficient liquid to treat 50 kg of body weight. Turn the knurled ring up the plunger shaft so that the side nearest the barrel is at the prescribed weight marking. Remove the plastic cap from the tip of the nozzle.

Administration: Clear the horse’s mouth of any food material, elevate the horse’s head, and using a syringe, deposit the appropriate dose in the back of the mouth. In order to avoid unnecessary coughing or the potential for material to enter the trachea and lungs, do not use excessive pressure (squirting), do not use a large (diluted) dose volume, and do not deposit the dose in the laryngeal area. Increased dose rejection may occur if the dose is deposited in the buccal space. Keep the horse’s head elevated and observe the horse to ensure the dose is retained.


All horses should be included in a regular parasite control program with particular attention being paid to mares, foals, and yearlings. Foals should be treated initially at 6 to 8 weeks of age. The program should be designed to accommodate the needs of horses and their specific husbandry and conditions.Ivermectin Liquid for Horses is highly effective against gastrointestinal nematodes and bots in horses. Regular treatments will reduce the chances of verminous arteritis and colic caused by S. vulgaris. If there is a high risk of re-infection with P. equorum, foals should be re-treated at 6-8 week intervals. With its broad spectrum, IVERMECTIN LIQUID for horses is well suited to be the major component in a parasite control program. Consult your veterinarian for parasite control programs to meet your specific needs.


1. Ivermectin Liquid for Horses has been formulated specifically for use in horses only. The product should not be used in other animal species as severe adverse reactions, including fatalities in dogs, may result.

2. Some horses have experienced reactions with swelling and itching shortly after treatment. In most such cases, the horses have been diagnosed as carrying heavy infections of Onchocerca microfilariae, and it is assumed that the reactions were the result of microfilariae dying in large numbers. Although the signs have resolved spontaneously in a few days, symptomatic treatment may be advisable. Consult your veterinarian should these symptoms persist.
