Pen ink poison?

I got some pen ink in my mouth and I washed it out , but I am afraid that I might have swallowed some. Is this something I should worry about? Is pen ink poisonous?

it all depends on how much was in your mouth, and if you swallowed any. if there was not a lot of ink then you do not have to worry about anything. but if something unusual happens then you should go see someone proffesional pronto!
