If the chemical was swallowed, immediately give the person water. DO NOT give water if the patient is vomiting or has a decreased level of alertness.

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

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 U.S. 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 National Poison Control center.

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.

The patient may receive:

• Fluids by IV
• Medicines to treat symptoms
• Medicines to treat the allergic reaction
• Activated charcoal
• Methods to make the person throw up 
• Endoscopy
• A nasogastric (NG) tube thru the nose into the stomach to empty the stomach (gastric lavage)  
• Washing of the skin (if product touched skin)

Outlook (Prognosis)

How well a person does depends on whether the allergic reaction can be controlled. If a person survives longer than 24 hours, they will probably recover.
