Don’t drink the ink
The bottom line
Pen ink contains a solvent, resin, and a pigment or dye—among varied ingredients. The amount of ink in a pen is small and should not cause toxicity if eaten. Pen ink is considered non-toxic on the skin and can be washed off with soap and water or rubbing alcohol. The main risks of do-it-yourself stick-and-poke tattooing with ink are pain and infection.
Prevention Tips
Store pens and especially ink bottles up, away, and out of sight of children.
Keep the cap on pens and ink bottles when not using.
Use pens as intended (on paper and similar materials).
Keep pen ink away from the face, mouth, and eyes.
When getting an ink tattoo, always use a licensed tattoo artist with single-use disposable equipment.
This Really Happened
On a dare, a 12-year-old boy sucked all the ink out of a ballpoint pen while walking home from school with friends. When his mom saw the ink on his mouth and tongue, she became concerned even though he felt fine. She called her poison center and was instructed to wipe out his mouth and have him swish and spit out a glass of water. She was assured that he would be fine.

What is pen ink made of?
While pen ink contains many ingredients, the 3 main ingredients are a solvent (such as glycols or glycol ethers), resin, and a pigment or dye for color. Other possible ingredients include alcohols (such as benzyl alcohol), lubricants, carbon, aniline, dextrin, glycerin, and fluorescents.
What happens if you eat ink from a pen?
The amount of ink in a pen is small (usually 0.7-1.2 mL). Therefore, eating the ink from a pen should not cause toxicity. It will stain your mouth and tongue and may cause a mild upset stomach. Fountain pen cartridges may hold up to 2.5 mL, while bottles of ink for calligraphy vary in size but are usually around 30 mL (or 1 oz.). Ingredients may differ between products. While risk of toxicity from swallowing these products may be higher because of the larger volume of ink involved, the risk is still relatively low for most ink formulations.
Is pen ink toxic for skin? Does pen ink cause skin cancer?
Pen ink is considered non-toxic on the skin, but may stain it. Pressing the point of the pen into your skin could result in an infection. Ink does not cause skin cancer.
Is pen ink safe for stick-and-poke tattoos? Does pen ink go into your bloodstream?
Stick-and-poke tattooing involves dipping a needle in ink and then pricking the skin with dots of ink one at a time. If it is done by a trained tattoo artist under hygienic conditions, it should be safe, and the ink will not enter your bloodstream. If you or an untrained friend do it, there is a higher risk of pain and infection.
What should I do if I get pen ink in my mouth, eye, or wound?
If you get ink in your mouth, wipe your mouth out with a damp cloth and rinse with water. It may take time for the ink to fade. If it is on your skin or in a wound, you can initially try washing it with soap and water. If this is ineffective, you can gently scrub with rubbing alcohol (that is, isopropyl alcohol). If you get ink in your eye, rinse with water for 15 minutes. Do not use rubbing alcohol in your eyes.
