When starting your dog on ivermectin for heartworm prevention, it's important to be aware of potential side effects, even though most dogs tolerate it well.
- Lethargy or weakness
- Vomiting or diarrhea
- Lack of appetite
- Excessive drooling
- Incoordination or staggering
- Seizures (in rare cases)
Monitoring your dog for these symptoms is crucial, especially if she's taking ivermectin for the first time. Dogs with certain genetic mutations, like the MDR1 mutation, may be more sensitive to ivermectin and other medications. If you notice any of these signs, contact your veterinarian promptly as they might require immediate attention.
