Objective– To describe the clinical manifestations and treatment of Rauwolfia serpentina toxicity in a dog.
Case Summary– A 9-month-old intact male mixed breed dog was presented following ingestion of an antihypertensive medication containing alkaloids from R. serpentina. R. serpentina alkaloids cause depletion of the biologic amines: norepinephrine, dopamine, and serotonin. The dog experienced hypotension, mental depression, bradycardia, diarrhea, bronchoconstriction, and gastrointestinal ulceration similar to the adverse effects reported in humans. The dog was released from the hospital after 4 days of supportive care.
New Information Provided– This is the first case of accidental R. serpentina toxicity in a dog reported in the literature. This case had a good clinical outcome with supportive care and monitoring of all the subsequent adverse effects.
