Seek immediate medical help. DO NOT make a person throw up unless told to do so by Poison Control or a health care professional.
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, immediately give the person water or milk, unless instructed otherwise by a health care provider.
If the person breathed in the poison, immediately move him or her to fresh air.
Before Calling Emergency
Determine the following information:
The patient's age, weight, and condition
The name of the product (and ingredients and strengths, if known)
The time it was swallowed or contacted
The amount swallowed or contacted
Poison Control, or a local emergency number
In the United States, call 1-800-222-1222 to speak with a local poison control center. 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.
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. The patient may receive:
Breathing support, including breathing tube
Endoscopy -- camera down the throat to see burns in the esophagus and the stomach
Fluids by IV
Medicines to treat symptoms and pain
How well a patient does depends on the amount of poison swallowed and how quickly treatment was received. The faster a patient gets medical help, the better the chance for recovery.
Swallowing such poisons can have severe effects on many parts of the body. Damage continues to occur to the esophagus and stomach for several weeks after the potassium hydroxide was swallowed, and death may occur as long as a month later.
