Paradichlorobenzene is a white, solid chemical with a very strong odor. Poisoning can occur if you swallow this chemical.
This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.
These products contain paradichlorobenzene:
- Toilet bowl deodorizers
- Moth repellant
Other products may also contain paradichlorobenzene.
Below are symptoms of paradichlorobenzene poisoning in different parts of the body.
EYES, EARS, THROAT, AND MOUTH
- Burning in mouth
LUNGS AND AIRWAYS
- Breathing problems (rapid, slow, or painful)
- Shallow breathing
- Changes in alertness
- Slurred speech
- Yellow skin (jaundice)
STOMACH AND INTESTINES

- Nausea and vomiting
Get medical help right away. DO NOT make the person throw up unless poison control or a health care provider tells you to.
If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.
If the chemical was swallowed, give the person water or milk right away, unless instructed otherwise by a provider. DO NOT give water or milk if the person is unconscious (has a decreased level of alertness).

- Person's age, weight, and condition (for example, is the person awake or alert?)

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
Take the container to the hospital with you, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.
The person may receive:
- Fluids through a vein (by IV)
- Activated charcoal
- Tube through the mouth into the stomach to wash out the stomach (gastric lavage)
- Medicines to treat symptoms
- Breathing support, including tube through the mouth into the lungs and connected to a breathing machine (ventilator)
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 is swallowed, unless it causes choking. Mothballs have an irritating smell, which usually keeps people away from them.
More severe symptoms may occur if someone swallows the product on purpose, since larger amounts are usually swallowed.
