What It Is and How It Works

Ivermectin is an antiparasitic agent that works by binding to specific ion channels in the nerve and muscle cells of parasites. This binding disrupts normal nerve impulses, causing paralysis and eventually death of the parasites. In horses, it is highly effective against a variety of worms and other parasites that can affect their health and wellbeing.

Indications / Uses

The primary use of ivermectin paste in veterinary medicine is for the treatment and control of various internal parasites in horses. These include large and small strongyles, pinworms, roundworms, and bots. While ivermectin is also used in human medicine, the veterinary formulations should not be used by humans without explicit guidance from a healthcare provider.

Dosage Forms and Typical Dosing Considerations

Ivermectin paste is available in a syringe form designed for oral administration in horses. The concentration and dosage will depend on the weight of the horse and the specific parasites being targeted. It’s essential to use the correct formulation and dose, as improper dosing can lead to ineffective treatment or toxicity. Factors such as the horse’s age, health status, and concurrent medications should be considered by a veterinarian when determining the appropriate dose.

How to Take It Correctly Step-by-Step

For horses, the paste is usually administered orally using a special syringe that allows for precise dosing based on weight. It’s important to:

Ensure the horse’s mouth is clear of food.
Insert the syringe into the side of the horse’s mouth.
Depress the plunger to administer the paste.
Follow up with a veterinarian to confirm the effectiveness and observe for side effects.

Humans should not use this product without medical advice. If a dose is missed, consult a veterinarian for guidance rather than administering more medication than prescribed.

Special precautions should be taken when considering use in pregnant or lactating mares, and a veterinarian should be consulted. Horses with health issues or on other medications may require adjusted dosing or monitoring.

Drug, Food, and Supplement Interactions

While ivermectin is generally safe when used appropriately, it can interact with other medications. It is important to inform the veterinarian of all medications and supplements the horse is currently receiving. This includes other antiparasitic agents, which could increase the risk of side effects.
