Injectable Ivermectin for Horses: Working as Useful Dewormer

Injectable ivermectin is a commonly used veterinary medication in horses to control and treat a wide range of internal and external parasites. Here’s a comprehensive guide on its use, including dosage, administration, precautions, and more.

Introduction of Injectable Ivermectin for Horses

Injectable ivermectin is a widely used antiparasitic medication in horses, primarily effective against a variety of internal and external parasites. It belongs to a class of drugs known as macrocyclic lactones, which work by disrupting the nerve transmission in parasites, leading to their paralysis and death.

 

Purpose and Effectiveness

Ivermectin injection is highly effective against most common parasites in horses, including:

Internal parasites: such as strongyles (both small and large), pinworms, ascarids, hairworms, large-mouth stomach worms, lungworms, intestinal threadworms, etc.

External parasites: such as lice, bots (cause summer sores), and certain types of mites. It can also control the dermatitis caused by neck threadworms.

 

Dosage and Administration

Dosage recommendations: The typical dosage for ivermectin in horses is 200 micrograms per kilogram of body weight. The exact dosage should be determined based on the horse’s weight to ensure effectiveness and safety.

For foals, treatment usually begins at 6 to 8 weeks of age, with re-treatment every 6 to 8 weeks if there is a high risk of reinfection.

Administration Methods: Ivermectin is administered either subcutaneously (under the skin) or intramuscularly (into the muscle), depending on the product formulation and veterinary recommendations. Always follow the specific instructions provided by the manufacturer or your veterinarian.

Procedure:

Ensure the injection site is clean and dry.

Use a sterile needle and syringe.

If administering subcutaneously, inject at a site where there is loose skin, typically in the neck area.

If administering intramuscularly, the common sites include the neck or the hindquarters, avoiding areas of heavy muscle use.

Advantages and Benefits

The injectable form of Ivermectin offers a unique advantage: it delivers a controlled dosage directly into the bloodstream, ensuring immediate and comprehensive coverage against parasites. Then it works by disrupting the nervous system of the parasites, leading to their paralysis and subsequent elimination from the horse’s body.

Secondly, effective parasitic control can lead to improvements in the horse’s coat condition, appetite, and overall vitality. By reducing the parasitic load, Ivermectin injection allows the horse’s immune system to function more efficiently, thus enhancing its ability to resist other health challenges.

This comprehensive benefit underscores the importance of regular parasite management in maintaining optimal equine health. However, it is essential to consider potential side effects and ensure proper administration to avoid complications.

 

Side Effects and Precautions

Side effects: Most horses tolerate ivermectin well, but some may experience temporary discomfort at the injection site. Rarely, allergic reactions can occur, which require immediate veterinary attention.

Mild reactions at the injection site (swelling, pain)

Allergic reactions (rare)

Neurological symptoms (very rare, typically with overdose)

Special considerations:

Weight Accuracy: Accurate dosing is crucial; underdosing may lead to ineffective parasite control while overdosing can be toxic.

Pregnancy and Lactation: Consult a veterinarian before administering to pregnant or lactating mares, as safety in these animals has not been fully established.

Young Foals: Use with caution in very young foals or debilitated horses, as they might be more susceptible to the effects of ivermectin.

Drug Interactions: Be aware of potential interactions with other medications your horse might be taking.

Withdrawal and Storage Considerations

Withdrawal times: If the horse is intended for human consumption, observe the withdrawal period recommended by the manufacturer and local regulations (note: horse meat consumption is regulated and culturally specific).

Storage consideration: Store ivermectin injection in a cool, dry place and protect it from light to maintain its effectiveness.

Proper disposal: Dispose of any unused product or syringes according to local regulations to prevent environmental contamination and accidental exposure to other animals.

 

Is Ivermectin Injection Safe for Horses?

When given at the correct dose, it is considered safe for use in various equine populations, including foals, pregnant mares, lactating mares, and breeding stallions. Its selective toxicity ensures it’s effective against parasites but has little effect on mammals when used as directed.

 

How Long Does Ivermectin Injection Last in Horses?

The medication often has a duration of 8- 10 weeks.

 

Conclusion

Injectable ivermectin is a valuable tool in equine health management for controlling a broad range of parasites. Proper administration, adherence to dosage guidelines, and consideration of safety precautions are essential for achieving the desired therapeutic outcomes while minimizing risks. Always consult with a veterinarian to ensure appropriate use tailored to the specific needs and health status of the horse.
