Early signs include nausea, vomiting, diarrhea, dizziness, and abdominal pain. As toxicity progresses, individuals may experience rapid or slow heart rate, low blood pressure, confusion, and muscle weakness. In children, symptoms may appear more quickly and intensely. Severe cases require immediate medical intervention, as lethal doses can be fatal without prompt treatment.

Keep oleanders out of children’s reach, as curious hands often explore with taste. If a pet chews oleander, isolate the animal and contact a veterinarian immediately.
