If the menthol is in ointment/cream form, wipe away any that remains on the skin's surface. Call Poison Control for further guidance. Seek immediate emergency medical care.

Determine the following:

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

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
• Medicines to treat symptoms
• Activated charcoal
• 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

How well a patient does depends on how much poison was swallowed and how quickly medical treatment was received. 

Swallowing pure menthol can be deadly. One teaspoonful can cause death in infants. However, pure menthol is not readily available. The menthol found in many over-the-counter products is usually watered down and mixed with other ingredients. Therefore, how well a patient does also depends on the other ingredients in the product.
