What It Is and How It Works

Ivermectin is an antiparasitic agent that is primarily utilized to treat a variety of parasitic infections. As a dewormer for pigs, ivermectin functions by interacting with nerve and muscle cells of parasites, which increases the permeability of cell membranes to chloride ions. This action causes paralysis and eventually leads to the death of the parasites. It is effective against a wide range of parasites, including roundworms, lungworms, and external parasites such as mites and lice.

Indications / Uses

The primary use of ivermectin in pigs is to treat and control a variety of parasitic infections. Commonly treated parasites include:

• Gastrointestinal roundworms
• Lungworms
• Lice and mites responsible for mange

Ivermectin helps improve the health and growth rates of pigs by eradicating these parasites, leading to healthier animals and improved productivity on farms.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in several formulations for use in pigs, including injectable solutions, oral liquids, and topical applications. The choice of formulation and dosing depends on factors such as the age of the animals, weight, the specific parasites being targeted, and farm management practices.

Individualized dosing considerations may include:

• Age: Dosing may vary between young pigs and adults.
• Weight: Dosing adjustments are typically based on the weight of the pigs.
• Other Conditions: Any underlying health issues or concurrent treatments may influence dosing decisions.

Always follow veterinary guidance and dosing instructions on product labels.

How to Take It Correctly Step-by-Step

1. Timing: Administer ivermectin as directed under veterinary advice and according to the package instructions.
2. With or Without Food: Oral formulations do not typically require feeding adjustments, but check the product specifics.
3. Missed Dose: If a dose is missed, administer it as soon as possible. Do not double dose.
4. Storage: Store ivermectin in a cool, dry place, away from direct sunlight.

Avoid common mistakes such as improper dosing, using incorrect formulations, or failing to complete the treatment regimen.
