Quick Facts
- Purpose: Used to treat and control parasitic infections in horses.
- Mechanism: Works by disrupting nerve and muscle function in parasites.
- Common Forms: Available in oral paste form.
- Key Cautions: Overdose or incorrect dosage can be harmful.
- Common Side Effects: Rare but can include swelling, itching, and mild skin reactions.

What It Is and How It Works
Ivermectin is an antiparasitic medication that is effective against a range of internal and external parasites. In horses, it targets gastrointestinal worms, bots, and other parasites. The drug functions by binding to specific channels in nerve and muscle cells of the parasite, increasing the permeability of the cell membrane to chloride ions, causing paralysis and death of the parasite. This affects parasites but not the host animal when used as directed.
Indications / Uses
Horse ivermectin paste is primarily used to treat and manage infestations by parasites such as strongyles, ascarids, pinworms, and bots. It is a vital tool in managing the health of horses, contributing to improved digestion, nutrient absorption, and overall health by eliminating burdensome parasites.
Dosage Forms and Typical Dosing Considerations
Ivermectin for horses is commonly available as an oral paste, which is easy to administer. The appropriate dose is typically based on the weight of the horse, which highlights the importance of accurately weighing the animal before treatment. Ivermectin is usually administered as a single treatment, but the dosing schedule may vary based on the parasite being targeted and the health regimen prescribed by a veterinarian. Special caution should be observed in pregnant mares and foals, with professional insights from a veterinarian.
How to Take It Correctly Step-by-Step
Here\’s a step-by-step guide on administering horse ivermectin paste:
- Weigh the Horse: Utilize a scale or a weight tape specifically designed for horses to ensure an accurate measure.
- Adjust the Syringe: Ivermectin paste syringes are typically marked with dosage levels corresponding to weight. Adjust the syringe plunger to the correct dose for the horse’s weight.
- Administration: Insert the syringe into the space between the horse\’s cheek and teeth, and depress the plunger to administer the paste directly onto the back of the tongue.
- Ensure Ingestion: Observe the horse to confirm that the paste has been swallowed.
- Storage: Keep the paste at room temperature and out of reach of other animals and children.
Avoid double dosing or giving higher than recommended doses, as this can lead to toxicity.
Side Effects Common to Serious
Common Side Effects
Common side effects are rare but can include mild swelling and itching at the administration site. These symptoms typically resolve on their own.
Less Common Side Effects
In some cases, mild skin reactions have been noted, which may require a calmer environment and observation for recovery without intervention.
Serious or Rare Side Effects
Serious effects, such as signs of overdose, could potentially include tremors, ataxia (lack of muscle control), or more severe allergic reactions. These require immediate veterinary intervention.
Red-flag symptoms: Excessive drooling, inability to stand, and severe neurological symptoms warrant urgent veterinary care.
Contraindications & Precautions
Ivermectin should be used cautiously in specific horse populations, including pregnant mares and foals, under professional supervision. Horses with known hypersensitivity to ivermectin or related compounds should avoid the medication. It\’s essential to consult with a veterinarian for a comprehensive risk assessment if the horse has any known health conditions.
Drug, Food, and Supplement Interactions
Interactions with ivermectin may occur, particularly if used in combination with other antiparasitic drugs. Avoid using other medications that may lower seizure thresholds unless advised by a veterinarian. It\’s important to inform your vet about any other drugs or supplements the horse is taking to avoid potential interactions.
Price & Availability
The cost of ivermectin paste for horses can vary based on the brand, dosage, and place of purchase. Availability may also differ by region and demand. Here are some typical pricing factors:
| Factor | Considerations |
|---|---|
| Brand | Different brands may vary in cost and availability. |
| Dosage/Weight | The required dosage based on the horse\’s weight may affect total quantity needed. |
| Purchase Location | Costs can vary between veterinary clinics, online stores, and physical outlets. |
