Quick Facts
- Ivermectin is an antiparasitic medication used primarily in horses.
- It functions by paralyzing and killing parasitic worms.
- Common forms include oral paste, gel, and liquid solutions.
- The onset of action typically leads to parasite expulsion within 24-48 hours.
- Ensure proper dosage as overdosing can lead to toxicity.
- Possible side effects range from mild irritation to adverse neurological effects.
- Ivermectin is generally safe for most horses when used as directed.
- Possible interactions can occur with other products; consult a veterinarian.
- Emergency veterinary care may be needed in case of overdose or severe reaction.
What It Is and How It Works
Ivermectin is a broad-spectrum antiparasitic agent. It works by binding to glutamate-gated chloride ion channels in the nerve and muscle cells of parasites. This causes an increased permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. Importantly, while it is potent against a wide array of internal and external parasites, it has no significant efficacy against tapeworms, flukes, or fleas.
Indications / Uses
Ivermectin is primarily used in horses to control various parasites including strongyles, ascarids, bots, and other worms. It is essential for maintaining equine health, particularly in environments where parasitic infections are common. Although ivermectin is primarily directed at parasite control, always consult a veterinarian before use to confirm it is suitable for your horse.
Dosage Forms and Typical Dosing Considerations
Ivermectin for horses is commonly available as an oral paste, gel, or liquid solution. The concentration and form might vary across different brands. Dosage is based on the horse\’s weight and typically given at intervals recommended by a veterinarian. It is crucial to avoid overdosing, especially with smaller or juvenile horses, as this can lead to toxic side effects.
How to Take It Correctly Step-by-Step
Administer ivermectin based on weight-dosing recommendations:
- Use a weight tape or scale to accurately determine the horse’s weight.
- Adjust the dispensing apparatus according to the calculated dosage.
- Ensure the horse’s mouth is clear of food.
- Insert the applicator at the corner of the horse\’s mouth, aiming toward the back of the mouth.
- Depress the plunger fully, then hold the horse’s head upward for a few seconds to ensure swallowing.
- Store remaining product at room temperature and avoid contamination.
If a dose is missed, consult your veterinarian before administering a supplementary dose to avoid overdosing.
