Another other type of rodenticide is bromethalin, which is a neurotoxin and does not affect clotting ability. The most common brands are Assault and Vengence and they can also be green pellets. Symptoms occur within several hours of ingestion and include depression, paralysis, tremors, or seizures. Decontamination with vomiting or gastric lavage should occur if ingestion is witnessed. Supportive care and control of neurological symptoms is key. Death usually occurs from respiratory failure secondary to paralysis. Prognosis is very guarded as only a small amount of bait is needed to cause symptoms.
A third type involves cholecalciferol, or vitamin D. This can lead to elevated levels of calcium in the blood, leading to arrhythmmias, seizures, and kidney failure. Onset of symptoms, including vomiting, diarrhea, and lethargy, is within 18-36 hours. Treatment includes decontamination where applicable, aggressive IV fluid therapy, and monitoring of kidneys and heart. A drug called pamidronate can be used to try and lower calcium levels in the blood.
If you suspect your pet has gotten into any type of rodenticide, contact your vet or Poison Control immediately. If possible, have the packaging on hand because the active ingredient is important in guiding treatment.
