If boric acid is on the skin, remove by washing the area. If boric acid was swallowed, give lots of water or milk, then call Poison Control for guidance.

If instructed to induce vomiting, proceed as follows or as otherwise instructed:

Give the appropriate dose of ipecac syrup: 15 milliliters (ml) or 1 TABLEspoonful for children and 30 ml (2 TABLEspoonsful) for an adult.
Follow with 1/2 glass or 4 ounces (oz.) of water for children or 8 to 12 oz. of water for adults.
Repeat 1 more time in 1/2 hour if vomiting has not occurred.

Before Calling Emergency

Determine the following information:

The patient's age, weight, and condition
The name of the product (ingredients and strengths if known)
When it was swallowed
The amount swallowed

Poison Control, or a local emergency number

If you are concerned about exposure or poisoning with boric acid, seek emergency medical care immediately at your nearest emergency room. See poison control centers for the national telephone number. Take any containers with you to the emergency room.

What to expect at the emergency room

Some or all of the following procedures may be performed:

Inducing vomiting
Administering activated charcoal
Administering a laxative
Pumping the stomach (gastric lavage).
Giving liquids by mouth or intravenously.
Administering kidney dialysis.
Treating other symptoms.

Expectations (prognosis)

Prognosis and risk of death depends on the extent of exposure and how much time passed before treatment. There is high death rate in infants who have ingested enough boric acid to exhibit symptoms of an overdose.
