What are the risks or side effects of ivermectin in dogs?
While generally safe for dogs when used at appropriate doses prescribed by a veterinarian, ivermectin can cause adverse reactions, particularly in certain breeds. Dogs with a specific genetic mutation (MDR1 gene mutation, also known as the ABCB1 gene mutation) are highly sensitive to ivermectin and can experience severe neurological side effects, including:
* Vomiting
* Drooling
* Lethargy
* Tremors
* Seizures
* Coma
* Death
Breeds commonly affected by this mutation include Collies, Australian Shepherds, Shetland Sheepdogs, Old English Sheepdogs, and Border Collies, among others. It is essential for veterinarians to be aware of this sensitivity when prescribing ivermectin. Overdosing can also lead to toxicity in any dog.
