Before Calling Emergency

Determine the following information:

Name of the product (ingredients and strengths, if known)
Time it was swallowed
Amount swallowed

However, DO NOT delay calling for help if this information is not immediately available.

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.

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
Fluids through a vein (by IV)
Laxative
Medicines to treat symptoms
Tube through the mouth into the stomach to wash out the stomach (gastric lavage)

Expectations (prognosis)

This type of poisoning is usually not life threatening. Little will likely happen if your child accidentally puts a moth ball in the mouth, even if it's swallowed, unless it causes choking. Mothballs have an irritating smell, which usually keeps people away from them.

More severe symptoms may occur if someone intentionally swallows the product, since larger amounts are usually swallowed.
