Candles are made out of wax. Candle poisoning occurs when someone swallows candle wax. This can happen by accident or on purpose.
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.
The substances in candles that can be harmful are:
- Paraffin wax
- Man-made (synthetic) wax
- Vegetable oil based wax
Candle wax is considered nonpoisonous, but it may cause a blockage in the intestines if a large amount is swallowed.
Blockage in the intestines
Intestinal obstruction is a partial or complete blockage of the bowel. The contents of the intestine cannot pass through it.
Seek medical help right away. DO NOT make the person throw up unless poison control or a health care provider tells you to.

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
A trip to the emergency room may not be necessary.
If medical care is needed, 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 a laxative to help the wax move quickly through the stomach and intestines. This will help prevent a bowel blockage.
Candle wax is considered nonpoisonous, and recovery is very likely.
How well someone does depends on how much wax they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.
