Poison Control, or a local emergency number If you suspect possible poisoning, seek emergency medical care immediately. The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions. This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week. Take the container with you to the hospital, if possible. See: Poison control center - emergency number What to expect at the emergency room The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. Persons who have recently eaten many mothballs will be forced to vomit. Other treatments may include: - Activated charcoal
- Blood transfusion (rarely)
- A medicine called methylene blue if methemoglobinemia is present
Expectations (prognosis) It can take several weeks or longer to recover from some of the poisonous effects. If the patient has convulsions and coma, the outlook is not good.
