Quick Facts
- Ivermectin is used to treat parasitic infections in horses.
- It works by interfering with the nerve and muscle functions of parasites.
- Commonly available in paste form for oral administration to horses.
- Typical onset of action is within 24 hours, effective for several weeks.
- Monitor horses for adverse reactions, especially those with heavy parasite loads.
- Potential side effects include skin reactions and gastrointestinal disturbances.

What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to glutamate-gated chloride ion channels in the nerve and muscle cells of parasites. This binding results in increased permeability of cell membranes to chloride ions, causing paralysis and death of the parasites. For horses, it is effective against a wide range of internal and external parasites, including lice, mites, and various worms.
Indications / Uses
In horses, ivermectin is primarily used to combat parasitic infestations. It is effective against bots, pinworms, roundworms, and strongyles, among others. While primarily approved for these uses, veterinarians might recommend ivermectin off-label to address specific parasite-related conditions, always under professional guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin for horses is most commonly administered as an oral paste, with syringes calibrated to deliver dosage based on weight. The dosage may vary depending on the infestation and the horse\’s weight, with general doses ranging from 0.2 to 0.5 mg per kilogram. Age, liver and kidney function, and concurrent use of other medications can affect dosing decisions. Professional medical advice is crucial for accurate dosing.
How to Take It Correctly Step-by-Step
- Administer ivermectin orally, following the weight-based dosing instructions on the product label.
- Ensure the horse\’s mouth is free of food prior to administration.
- If a dose is missed, administer it as soon as possible, and adjust subsequent administration to current events, not delaying.
- Store ivermectin at room temperature, away from humidity and direct sunlight.
- Avoid administering additional doses without guidance, as overdosing can lead to toxicity.
Side Effects Common to Serious
Common Side Effects
Common side effects of ivermectin in horses include temporary grogginess and slight gastrointestinal upset. In most cases, these symptoms resolve without intervention.
Less Common Side Effects
Rarely, horses may experience sensitivity to ivermectin resulting in skin reactions such as swelling and itching.
Serious or Rare Side Effects
Serious adverse effects can include neurological symptoms such as seizures, and severe allergic reactions manifesting as difficulty breathing or intense swelling. Immediate veterinary attention is necessary if these occur.
Contraindications & Precautions
Ivermectin should not be used in horses that are intended for human consumption. Caution is advised when using in very young foals, or those with known hypersensitivity to ivermectin. Pregnant and breeding mares should be evaluated by a veterinarian to assess risk versus benefit. Horses with liver or kidney impairments might require adjusted dosing.
Drug, Food, and Supplement Interactions
While ivermectin does not have widespread interactions, concurrent use of medications such as ketamine or midazolam can enhance adverse neurological effects. Always inform your veterinarian about any additional supplements, herbs, or medications your horse may be receiving.
