Emergency now (benzodiazepines, cooling, vitamin C acidification as support) — bring the bottle.
Toxicity notes
A single tablet poisons a pet (10-12× the human therapeutic dose is dangerous) — causing agitation, tremors, hyperthermia and organ failure.
Poisoning symptoms
- • Agitation
- • Tremors
- • Soaring heart rate and blood pressure
- • High fever
- • Seizures
Symptoms can be delayed (e.g. onion/garlic-induced hemolysis may take days) — a pet looking fine right now is no reason to relax.
FAQ
How much causes poisoning?
A single tablet poisons a pet (10-12× the human therapeutic dose is dangerous) — causing agitation, tremors, hyperthermia and organ failure.
Can I make my pet vomit at home?
Home-induced vomiting is not advised: corrosive cleaners, sharp bones or existing neurological signs make it dangerous, and improper technique risks aspiration pneumonia. Vomiting should be induced by a vet with proper drugs at the right moment — most effective within 1-2 hours. So “head to the clinic as soon as you know” beats “try to induce vomiting first”.
