Seek immediate emergency medical care. Most of the symptoms listed result from breathing in (inhaling) the substance.  Move the person to fresh air. Be careful to avoid being overcome with the fumes while helping someone else.  Contact Poison Control for further information.

Determine the following information:

• The patient's age, weight, and condition

• The name of the product (ingredients and strengths, if known)

• The time it was swallowed or inhaled

• The amount swallowed or inhaled

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.  This is a free and confidential service. All local poison control centers in the U.S. 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.  Take the container with you to the hospital, if possible.  See National Poison Control center.

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:

• Fluids by IV

• Medicines to treat symptoms

• A nasogastric (NG) tube thru the nose into the stomach to empty the stomach (gastric lavage)

• Medicines to treat an allergic reaction (diphenhydramine, epinephrine, or prednisone)

• Endoscopy -- the placement of a camera down the throat to see the extent of burns to the esophagus and the stomach

• Medicine (antidote) to reverse the effect of the poison

• Irrigation (washing of the skin), perhaps every few hours for several days

• Skin debridement (surgical removal of burned skin)

• Breathing tube

• Oxygen

How well a patient does depends on the severity of the poisoning and how quickly medical help was received.  Severe lung damage may occur. Survival past 72 hours usually means the patient will have a complete recovery.  Long-term abusers of freon can have permanent brain damage and early death.
