Boric acid is a dangerous poison. Poisoning from this chemical can be acute or chronic. Acute boric acid poisoning usually occurs when someone swallows powdered roach-killing products that contain the chemical.
Chronic poisoning occurs in those who are repeatedly exposed to boric acid. For example, in the past, boric acid was used to disinfect and treat wounds. People who received such treatment over and over again got sick, and some died.
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.
Boric acid is found in:
Note: This list may not be all inclusive.
The main symptoms of boric acid poisoning are blue-green vomit, diarrhea, and a bright red rash on the skin. Other symptoms may include:
If the chemical is on the skin, remove it by washing the area thoroughly.
If the chemical was swallowed, seek medical treatment immediately.
If the chemical contacted the eyes, wash them out with cool water for 15 minutes.
Before Calling Emergency
Determine the following information:
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. This hotline number will let you talk to experts in poisoning. They will give you further instructions.
This is a free and confidential service. 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.
What to Expect at the Emergency Room
The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Treatment depends on the individual symptoms. The person may receive:
Note: Activated charcoal does not effectively treat (absorb) boric acid.
For skin exposure, treatment may include:
The person may need to be admitted to a hospital for more treatment. Surgery may be needed if the esophagus, stomach, or intestine has a hole (perforation) from the acid.
The infant death rate from boric acid poisonings is high. However, boric acid poisoning is considerably rarer than in the past because the substance is no longer used as a disinfectant in nurseries. It is also no longer commonly used in medical preparations. Boric acid is an ingredient in some vaginal suppositories used for yeast infections, although this is NOT a standard treatment.
