• When it was swallowed
• The amount swallowed

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 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:

• Blood tests
• Medicines to treat symptoms
• Activated charcoal
• A nasogastric (NG) tube thru the nose into the stomach to empty the stomach (gastric lavage) 

Expectations (prognosis)

Because calcium carbonate is considered a fairly nontoxic substance, recovery is quite likely. Chronic overuse is more serious than a single overdose.
