Ivermectin is a medicine designed to kill parasites in dogs. In the United States, one of its branded forms is called Stromectol. Stromectol and other ivermectin-based medicines work by shortening the lives of adult parasites and killing the young ones.
Stromectol comes in three forms: topical skin cream, injectable and pill. In any form, Stromectol is safe as long as it is used according to the veterinarian's instructions. Used topically, the drug kills mites, lice, mange and scabies. Taken internally, Stromectol kills heartworms, nematodes and other dangerous parasites.
Ivermectin causes many side effects in dogs when used improperly, including intoxication of the animal, breathing difficulties and potentially death. Common symptoms of ivermectin overdose are lethargy and depression, vomiting, excessive drooling and loss of appetite. The pupils may dilate, and the dog could experience voluntary motor control problems, including tremors and seizures. The dog may lose his ability to stand, become blind, and suffer respiratory distress and a slow heartbeat.
