This is poisoning from swallowing ink found in writing instruments (pens). 

Writing ink is generally considered non-toxic.

• Pens

• May cause eye irritation
• Staining of skin and other mucous membranes

Seek immediate medical help.

Note: Large amounts of writing ink must be consumed (more than an ounce) before treatment is necessary. Contact Poison Control or your local emergency number for more 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
• 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.

Some or all of the following procedures may be performed:

• Washing of ink from the eyes or skin
• Treat the symptoms

As these products are generally considered non-toxic, recovery is very likely.
