What It Is and How It Works
Ivermectin belongs to a class of medications called avermectins, which work by paralyzing and killing parasites. It disrupts nerve and muscle functions in parasites, leading to their death. While it is effective against a wide range of parasites, it is important to use it only as directed by a veterinarian.
Indications / Uses
Ivermectin is primarily used to treat parasitic infections in animals such as horses, cattle, pigs, dogs, and cats. It is effective against:
- Heartworms in dogs and cats
- Roundworms, lungworms, and other intestinal worms in livestock
- Mites and lice in various animals
Off-label uses exist but should only be pursued under veterinary guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, including:
- Injectable solutions
- Oral tablets and chewables
- Topical solutions
The appropriate form and dosage depend on the type of animal, its weight, the specific parasite being targeted, and other health considerations. Always follow the veterinarian’s prescription and guidance.
