Moxidectin Poisoning: What is it?

Moxidectin is a drug used to treat parasitic infections in dogs, cats, and large farm animals. This is similar to other anthelmintic drugs such as ivermectin and milbemycin, in that it interferes with crucial neurotransmissions in parasites, causing them to become paralyzed and die. A number of different parasites can be treated with Moxidectin, which is available in oral, topical, and injectable forms.

Dogs and other animals often use it for treating heartworm. The use of moxidectin in dogs is safe in the correct dosage, but side effects can occur. Moxidectin poisoning can result in severe symptoms or even death when taken in high doses that can cross the blood-brain barrier. Ingestion or topical exposure can result in poisoning. 

There are certain breeds of herding dogs that are particularly susceptible to moxidectin poisoning because they are sensitive to avermectin. Even a small dose of drugs can be toxic to these dogs due to a mutation that lets drugs easily cross the blood-brain barrier.

Large doses of parasite medications for horses and other farm animals often cause toxicity in animals that are not sensitive. Symptoms have also been reported in dogs who ingest horse feces immediately after the horses were dewormed. Symptoms of moxidectin poisoning include nausea, vomiting, and excessive salivation. In most cases, treatment is successful.

Dogs and other animals are treated with moxectin to kill parasites. Moxidectin overdose can cause life-threatening neurological symptoms, but it is safe in recommended doses.

A major financial burden can be incurred by treating moxidectin poisoning on your own. The majority of pet insurance companies reimburse claims within 3 days, putting 90% of the bill back in your pocket.
