Before Calling Emergency
Determine the following information:
- the patient’s age, weight, and condition
- the name of the product (ingredients and strengths if known)
- the time it was swallowed
- the amount swallowed
Poison Control, or a local emergency number
They will instruct you if it is necessary to take the patient to the hospital. See Poison Control Centers for telephone numbers and addresses. Take the container with you to the emergency room.
What to expect at the emergency room
Some or all of the following procedures may be performed:

- Treat the symptoms.
If treated promptly under proper medical care poisoning is rarely severe, unless the toxicity is due to a long-time accumulation. In that case the ultimate outcome depends on what damage has occurred in body organs affected by the metal.
