What It Is and How It Works
Ivermectin is an antiparasitic medication that primarily targets the nervous system of various parasites. By binding to the invertebrate\’s nerve and muscle cells, it increases the permeability of cell membranes to chloride ions, resulting in paralysis and death of the parasite. The specificity of its action on parasites makes it extensively safe for animals.
Indications / Uses
Ivermectin is commonly used in veterinary medicine to treat a range of parasitic infections, including:
- Heartworm: Used in both treatment and prevention of heartworm disease in dogs.
- Roundworms and Hookworms: Effective against these gastrointestinal worms in various animals.
- External Parasites: Treats skin mites, lice, and ear mites effectively.
- Lungworms: Used in livestock to treat lungworm infections.
Veterinarians may also prescribe it off-label for other parasitic infections, depending on professional judgement and regional practice guidelines.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including tablets, chewables, injectable solutions, and topical applications. The form and dosage depend on the type of animal, its size, age, health status, and specific infection being treated. Dosage adjustments may be necessary for animals with liver or kidney concerns, and professional guidance is essential.
