What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to a class of drugs called avermectins. Its primary action is on the neuromuscular system of parasites. By binding to specific chloride channels, it increases the permeability of the cell membrane to chloride ions, resulting in muscle paralysis and eventual death of the parasite.
In more technical terms, ivermectin acts on the gamma-aminobutyric acid (GABA) and glutamate-gated chloride channels found in invertebrate nerve and muscle cells. This specificity makes it safe for use in horses, as these channels do not exist in the same form in mammals.
Indications / Uses
The primary approved use of ivermectin horse wormer paste is in the control and elimination of parasitic infections in horses. Common indications include:
- Treatment of gastrointestinal roundworms.
- Control of lungworms.
- Eradication of bots and other parasites that affect horses’ health and performance.
Its usage must strictly follow veterinary guidance, especially regarding the specific type of parasites affecting the horse.
Dosage Forms and Typical Dosing Considerations
Ivermectin horse wormer paste is typically available in an oral paste form, designed for easy administration to horses. The paste is formulated to provide a specific dose based on the weight of the horse.
General dosing principles include:
- The dosage is usually calculated based on the horse\’s weight to ensure efficacy and safety.
- It is crucial to use a calibrated syringe to deliver the correct amount of paste.
- Special considerations should be made for pregnant mares, foals, and animals with compromised health, always under veterinary supervision.
- Withdrawal periods may apply for horses intended for meat production.
How to Take It Correctly Step-by-Step
When administering ivermectin horse wormer paste, adhere to the following steps to ensure accuracy and safety:
- Weigh the horse accurately to determine the correct dosage.
- Ensure the horse’s mouth is empty of food.
- Set the syringe to the appropriate dosage mark based on the horse\’s weight.
- Insert the syringe slowly into the horse\’s mouth, aiming towards the back of the tongue.
- Depress the plunger to administer the paste.
- Hold the horse\’s head up for a few seconds to encourage swallowing.
- Store any unused paste as directed, typically in a cool, dry place.
Avoid common mistakes such as administering the wrong dosage or cross-contaminating with other medications.
