What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the macrocyclic lactones class. It works by interfering with nerve and muscle functions in parasites, leading to their paralysis and eventual death. The medication is absorbed into the bloodstream and targets parasites efficiently, providing a comprehensive treatment against infestations.
Technical details: Ivermectin binds to glutamate-gated chloride channels in nerve and muscle cells of parasites, which increases the cellular permeability to chloride ions and leads to paralysis.
Indications / Uses
Ivermectin paste wormer is primarily indicated for deworming horses. It treats infestations with the following types of parasites:
- Large strongyles (Strongylus spp.)
- Small strongyles
- Pinworms (Oxyuris equi)
- Ascarids (Parascaris equorum)
- Hairworms (Trichostrongylus axei)
- Lungworms (Dictyocaulus arnfieldi)
- Intestinal threadworms (Strongyloides westeri)
It is often used as part of a regular deworming program tailored to the needs of specific animal populations, seasons, and environments.
Dosage Forms and Typical Dosing Considerations
Ivermectin for horses is typically available in paste form, with syringes designed for oral administration. The usual dosing is calculated based on the animal\’s body weight to ensure efficacy while minimizing the risk of overdose.
- Typical Dosage: Approximately 200 micrograms of ivermectin per kilogram of body weight.
- It is crucial to weigh the animal accurately to determine the correct dose.
Special dosing considerations include:
- Young Animals: Consult a veterinarian for guidance on appropriate use.
- Pregnant or Lactating Animals: Safety must be discussed with a veterinarian due to limited data on reproductive safety.
- Senior Animals: Dosages may need adjustments based on general health status.
As with all medications, follow the label and veterinarian instructions closely.
How to Use It Correctly Step-by-Step
- Weigh the Animal: Ensure accurate weight measurement for correct dosing.
- Adjust the Syringe: Set the dose on the plunger dial according to the weight of the animal.
- Administer the Paste: Insert the syringe into the animal\’s mouth over the tongue and depress the plunger fully to deliver the paste.
- Observe the Animal: Monitor the animal for any adverse reactions following administration.
- Storage: Store unused paste at room temperature, away from direct sunlight.
Common mistakes include inaccurate weight estimation leading to improper dosing, and improper syringe technique leading to incomplete administration.
