The local poison control 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 national hotline 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 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.

Bring the container with you to the hospital, if possible.

Your provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.

Tests that may be done include:

• Blood and urine tests
• Chest x-ray
• Endoscopy -- camera placed down the throat to check for burns in the esophagus and stomach

Treatment may include:

• Breathing support, including tube through the mouth into the lungs and breathing machine (ventilator)
• Fluids through a vein (by IV)
• Laxative
• Medicine to treat symptoms
• Tube through the nose into the stomach if vomiting blood

How well someone does depends on the amount of cologne swallowed and how quickly treatment is received. The faster medical help is given, the better the chance for recovery.

Cologne poisoning may make a person appear as if they are drunk. It can also cause severe breathing problems, seizures, and coma. A product with a lot of isopropyl alcohol could cause a more serious illness.
