What It Is and How It Works
Ivermectin is an antiparasitic medication that works by interfering with the nervous system and muscle function of parasites, leading to their paralysis and death. In dogs, it is primarily used to prevent heartworm disease and treat intestinal worms such as roundworms and hookworms, as well as external parasites like mites. Its effectiveness and broad spectrum of activity make it a popular choice in veterinary medicine.
Indications / Uses
Ivermectin tablets are primarily used for the prevention and treatment of various parasitic infections in dogs:
- Heartworm Prevention: Ivermectin is widely used to prevent heartworm disease, a potentially life-threatening condition caused by parasitic worms in the heart and lungs.
- Intestinal Parasites: It is effective against common intestinal worms, including roundworms and hookworms.
- Mites: Ivermectin can be used to treat certain mite infections, such as mange.
Off-label use should only occur under the supervision of a veterinarian, as not all breeds are suitable candidates for ivermectin treatment.
