What It Is and How It Works
Ivermectin is an antiparasitic medication belonging to the avermectin class, which works by disrupting the nervous systems of parasites. It binds to specific channels in the cells of parasites, increasing the permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. This mechanism effectively targets a wide range of internal and external parasites.
Indications / Uses
Ivermectin is primarily used in dogs for the prevention and treatment of heartworm disease and other parasitic infestations such as ear mites, mange, and intestinal worms. While its use is common, it must always be administered under the guidance of a veterinarian due to potential breed-specific risks and interactions with other medications.
Dosage Forms and Typical Dosing Considerations
Ivermectin for dogs is available in various formulations, including oral tablets, chewables, injectables, and topical solutions. The dosing often depends on the specific condition being treated, as well as the dog’s weight, age, and overall health. Veterinarians will typically prescribe a dose based on these factors, and it is crucial to follow their instructions precisely.
How to Administer Ivermectin to Dogs: Step-by-Step
