Toxicology myths can lead to overtesting and overtreatment

A new dvm360 Vet Blast Podcast episode is spotlighting a quiet but costly issue in companion-animal medicine: misconceptions about toxic ingestions can drive unnecessary hospitalization, premature diagnostics, and one-size-fits-all treatment plans. In the March 3, 2026 episode, Renee Schmid, DVM, DABT, DABVT, senior veterinary toxicologist and director of veterinary medicine at Pet Poison Helpline, told host Adam Christman, DVM, MBA, that clinicians need to “treat the patient, not the toxin,” rather than defaulting to rigid toxicology algorithms.

The timing is deliberate. dvm360 framed the episode as part of Pet Poison Prevention Month, using the discussion to revisit persistent myths around veterinary toxicology. According to the article accompanying the podcast, Schmid’s conversation centered on several recurring decision points in practice: when inducing vomiting is appropriate, when activated charcoal is actually useful, when patients can be managed as outpatients, and when hospitalization is warranted.

The most practical takeaway is that exposure alone doesn’t dictate the care plan. In the transcript excerpt published by dvm360, Schmid used ibuprofen as an example, noting that some patients may face risk for gastrointestinal ulceration or acute kidney injury, while others may not. She also pointed to stimulant exposures, including amphetamines, where extensive laboratory testing may not provide meaningful information because clinicians typically do not expect the red cell, white cell, or organ-function changes that standard panels are designed to detect. In those cases, she suggested that outpatient medications, oral therapy at home, or selective fluid support may sometimes be reasonable, depending on clinical signs, finances, and the animal’s ability to tolerate hospitalization.

Schmid also highlighted a frequent toxicology error: ordering tests before pathophysiology has had time to declare itself. Her example was anticoagulant rodenticide exposure, where a clotting profile drawn just two hours after ingestion in a non-bleeding patient may create expense and handling stress without helping the clinician or the pet parent. That point aligns with broader toxicology guidance from ASPCA Poison Control, which notes that rodenticides remain a top toxin category and that different active ingredients can cause very different syndromes, from delayed coagulopathy to neurologic injury or kidney damage, making product identification and timing critical.

Industry context helps explain why this message matters now. ASPCA Poison Control said in 2025 that it had surpassed 5 million animal exposure cases since its hotline began in 1978 and that its team responds to more than 400,000 calls per year. Pet Poison Helpline, where Schmid serves in a leadership toxicology role, describes itself as a 24/7 service for both pet parents and veterinary professionals, with per-incident and subscription options, and recently emphasized rising acetaminophen exposure concerns linked to cold and flu medications in the home. Taken together, those data points suggest toxicology consult services are not niche support anymore; they’re core infrastructure for companion-animal practice. (aspca.org)

For veterinary professionals, the deeper significance is less about any single toxin than about clinical decision-making under financial and operational pressure. Schmid’s comments fit neatly into the profession’s broader shift toward spectrum-of-care medicine: matching intervention intensity to actual patient risk, available evidence, and what a pet parent can realistically pursue. In toxicology, that can mean resisting blanket protocols, using poison-center consultation earlier, and explaining to pet parents why “doing less” in the moment may actually be more medically appropriate.

There’s also a communication angle. Toxic ingestion cases are emotionally charged, and pet parents often expect immediate diagnostics or hospitalization because the word “toxin” sounds categorical. The podcast’s framing gives clinicians language to explain that toxicology is rarely black and white. Dose, formulation, route, timing, species, comorbidities, and current clinical signs all shape risk, and some exposures are better managed with observation and targeted follow-up than with automatic admission. That’s a useful message for teams trying to preserve trust while also controlling cost and reducing unnecessary patient stress. (dvm360.com)

What to watch: As poison-control data continue to shape case triage and as access-to-care pressures persist, expect more veterinary education and clinic protocols to focus on toxin-specific, time-sensitive decision-making rather than default diagnostic bundles or universal hospitalization.
