Inorganic arsenic: Insecticides such as ant/roach poisons, herbicides, wood preservatives, and some insulation.
Organic arsenic: Sodium caparsolate
and Filaricide (Two heartworm treatments and preventives).
Arsenic compounds cause reactions in the body that disrupt enzymes that are involved in cellular respiration, fat metabolism, and carbohydrate metabolism. They are especially damaging to the GI tract, kidneys, lungs, and skin.
Sodium arsenite: Dogs; 0.5-11 mg per pound. Cats; less than 2.25 mg per pound.
Sodium arsenate: Dogs; 3-6 mg per pound.
Vomiting, restlessness, drooling, nausea, severe abdominal pain often with bloody diarrhea with mucous in it, muscle weakness, trembling, staggering, severe dehydration, shock, paralysis, coma, and death.
Induce vomiting. Seek veterinary attention.
General treatment: The induction of vomiting may be continued, gastric lavage is performed, and activated charcoal is administered.
Supportive treatment: Hydration is maintained with IV fluids. Medications may be given to soothe and protect the GI tract.
Specific treatment: Chelation agents such as Dimercaprol (BAL) or Succimer (DMSA) are given to remove the arsenic from the body. Acetylcysteine may be given to reduce the toxicity to certain internal organs.
Grave, unless treatment is started before clinical signs are advanced.
