Ivermectin is a highly effective antiparasitic agent commonly used in veterinary medicine, notably for dogs. It is primarily used to treat various parasitic infections, including heartworm, mange, and certain types of intestinal worms. However, administering the correct dosage of ivermectin is crucial, as improper dosing can lead to severe side effects, particularly in sensitive breeds. This article will provide a comprehensive overview of ivermectin injection for dogs, including its uses, dosage guidelines, and precautions.

Understanding Ivermectin

Ivermectin belongs to a class of drugs known as macrocyclic lactones. It works by binding to specific channels in the parasite's nervous system, leading to paralysis and death of the parasite. It is important to note that while ivermectin is effective against many parasites, it is not a broad-spectrum anthelmintic and won’t be effective against every type of worm.

Uses in Dogs

In dogs, ivermectin is most commonly used for - Heartworm prevention Given as a monthly preventative. - Treatment of demodectic and sarcoptic mange Skin conditions caused by mites. - Treatment of certain gastrointestinal parasites Such as roundworms and hookworms.

Dosage Guidelines

The dosage of ivermectin can vary based on the condition being treated and the dog's breed and weight. Generally, the recommended dosage is

- For heartworm prevention 6 to 12 micrograms per kilogram of the dog's body weight, administered once a month. - For treatment of mange Dosages can vary from 300 to 600 micrograms per kilogram (0.3 to 0.6 mg/kg) for a series of injections, depending on the severity of the infestation.

Administering ivermectin as an injection is often used in cases of severe infestations or when immediate treatment is necessary.
