What It Is and How It Works
Ivermectin is an antiparasitic medication known for its effectiveness against a variety of parasitic infections in animals, including horses. It works by interacting with the nervous system of parasites. Specifically, ivermectin binds to glutamate-gated chloride channels unique to invertebrate nerve and muscle cells, resulting in increased permeability of the cell membrane to chloride ions, which leads to paralysis and death of the parasite.
This targeted mechanism makes ivermectin effective while minimizing adverse effects on the host animal when used as directed.
Indications / Uses
Ivermectin is primarily approved for the treatment and control of internal and external parasites in horses including strongyles, ascarids, pinworms, hairworms, lungworms, threadworms, stomach worms, and bots. These parasitic infections can severely impact the health and performance of horses if left untreated.
Off-label use of ivermectin exists, but it should only be done under strict veterinary supervision due to potential adverse effects and the development of resistance.
Dosage Forms and Typical Dosing Considerations
Ivermectin for horses is available in several formulations including paste, liquid, and injectable forms, though paste and liquid are more common. The appropriate dosing is generally determined by the horse’s weight, and accurate dosing is crucial to avoid underdosing or overdosing.
Standard dosing recommendations for ivermectin typically specify a dose of 0.2 mg per kg of body weight, although this may vary depending on the specific parasitic infection and health status of the animal. Pregnant mares, young foals, or sick animals may require adjusted dosing under veterinary guidance.
How to Take It Correctly Step-by-Step
To administer ivermectin correctly:
- Weigh the horse accurately to determine the correct dose.
- Select the appropriate formulation (paste or liquid) based on manufacturer\’s instructions and veterinary advice.
- Ensure mouth is clear before administering paste formulations directly onto the tongue.
- Apply as per veterinarian\’s guidance if using other formulations (e.g., injectables).
- Store ivermectin in a cool, dry place, away from light and out of reach of children and pets.
Avoid skipping doses, and never double doses if missed. If a dose is missed, administer the next dose as soon as possible and return to the regular schedule, unless otherwise directed by a veterinarian.
Side Effects Common to Serious
Common Side Effects
Mild stomach upset, diarrhea, and at times, mild visible swelling at injection site if injectable form is used.
Less Common Side Effects
Nervous system reactions such as lethargy and depression in cases of oversensitivity or overdose.
Serious or Rare Side Effects
Severe allergic reaction symptoms such as hives, difficulty breathing, and swelling require urgent veterinary care.
Contraindications & Precautions
Ivermectin is generally safe when used as directed but should be avoided in horses with known hypersensitivity to the drug. Caution is advised in using ivermectin in pregnant or lactating mares and in animals with concurrent illness without veterinary approval.
Elderly or debilitated animals should be carefully monitored when using this medication.
Drug, Food, and Supplement Interactions
Ivermectin may interact with other antiparasitic drugs. Always inform the veterinarian about all medications and supplements being administered to the horse. Alcohol does not apply, as ivermectin is used in horses, not humans.
