What to Expect at the Emergency Room
The health care provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. You may receive:
- Activated charcoal
- Blood and urine tests
- Breathing support
- Chest x-ray
- EKG (electrocardiogram, or heart tracing)
- Fluids through a vein (IV)
- Medication to treat symptoms, including an antidote to reverse the effects of the poison
- Tube through the mouth into the stomach to wash out the stomach (gastric lavage)
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 - 3 days and may require a hospital stay. Death is unlikely.
Do not touch or eat any plant with which you are not familiar. Wash your hands after working in the garden or walking in the woods.
