Why nutmeg is poisonous
Nutmeg contains myristicin, a compound that acts on the central nervous system and can cause neurotoxicity.
The toxin interferes with neurotransmitter balance, leading to tremors, hyperthermia and organ failure.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of nutmeg poisoning
- Repeated vomiting within 2‑4 hours after eating the spice
- Muscle tremors and unsteady gait by the afternoon
- Elevated heart rate and panting that worsen over hours
- Seizures or uncontrolled shaking in the evening
- Fever and drooling as the condition progresses
What to do right now
- Call your veterinarian or the Pet Poison Helpline immediately
- Provide details of the amount of nutmeg and the form (ground or whole)
- Do not induce vomiting if the pet is already vomiting or shows signs of seizures
- Keep the pet in a quiet, cool area to prevent overheating
- Transport to an emergency clinic for IV fluids and anticonvulsants
