What to Expect at the Emergency Room
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The person may receive:
- Activated charcoal
- Blood and urine tests
- Breathing support, including oxygen through a tube through the mouth into the lungs, and a breathing machine (ventilator)
- Chest x-ray
- ECG (electrocardiogram, or heart tracing)
- Fluids through a vein (IV)
- Medicines to treat symptoms and reverse the effects of the poison
How well you do depends on the amount of poison swallowed and how quickly treatment is received. The faster you get medical help, the better the chance for recovery.
Symptoms last for 1 to 3 days and may require a hospital stay. Death is unlikely.
DO NOT touch or eat any unfamiliar plant. Wash your hands after working in the garden or walking in the woods.
