What It Is and How It Works
Ivermectin is an antiparasitic agent that works by interfering with the nerve and muscle functions of parasites, leading to their paralysis and death. This makes it effective against a variety of parasites, including worms, lice, and mites. The pour-on formulation is designed for topical application, allowing the active ingredient to be absorbed through the skin and distributed throughout the pig’s body.
Indications / Uses
Ivermectin pour-on is primarily used to treat and control parasitic infections in pigs. These include:
- Internal parasites such as gastrointestinal roundworms.
- External parasites like lice and mites.
Maintaining a regular parasite control program is essential for the health and productivity of pigs, and ivermectin pour-on is a commonly used tool in achieving this goal.
Dosage Forms and Typical Dosing Considerations
Ivermectin pour-on is available in liquid form for topical application. The concentration and dosing depend on the specific product and the weight of the pigs being treated. It is crucial to follow the dosing instructions provided by the veterinarian or the product label to ensure effectiveness and safety.
Factors influencing dosing include:
- The pig’s weight and overall health.
