Child ate pentasa (mesalamine) what should i do?

Child eating somethi: Always call poison control to clarify the item ingested. The poison control number is usually an 800 no. And can be found in the front of your phone book, or any emergency room would have it and you could post it on your fridge or put it somewhere quickly accessible. My 10 mo old once put a handful of dishwasher soap in his mouth (not tasty!) but i called just to be sure.
