Poison Control, or a local emergency number
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.
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. The patient may receive:
- Activated charcoal
- Blood test to determine how much of the drug is in the blood
- Laxative
- Tube through the mouth or nose into the stomach to wash out the stomach (gastric lavage)
Expectations (prognosis)
The outcome depends on the symptoms.
- Mild -- The patient can be aroused. No further treatment will probably be necessary.
- Moderate -- Breathing and other vital signs are normal. The patient cannot be aroused. Recovery will probably occur within 24 - 48 hours with proper care.
- Severe -- Breathing and other vital signs may be abnormal. The patient cannot be aroused. Recovery will probably occur within 3 - 5 days, depending on the amount swallowed.
