Use on children? What IS this cream?

WHAT EXACTLY IS FLUOCINONIDE CREAM? IT IS A STEROID CREAM? MY 3-YR-OLD SON HAS HAD WHAT APPEARS TO BE ECZEMA SPONTANEOUSLY FOR ALMOST A YEAR, AND MY DAD HAD SOME OF THIS CREAM, AND, UNBEKNOWING TO ME, USED SOME ON HIM. I'M AFRAID TO USE A LOT OF STRONG MEDICATIONS, BUT HIS ARMS LOOK VERY MUCH BETTER. THE PEDIATRICIAN SAID THAT THE CONDITION IS AN ALLERGY, AND WE HAVE BEEN THROUGH THE "TRIAMCINOLONE"(STEROID) CREAM, BENADRYL, HYDROCORTISONE, BURT'S BEES "NATURAL" ALMOND MILK CREAM, FOOD ELIMINATION(SLOW PROCESS TRYING TO IDENTIFY POSSIBLE FOOD ALLERGY). ANYWAY, IS THIS CREAM SAFE TO USE ON CHILDREN? I'M AFRAID OF LONG-TERM EFFECTS OF STEROID CREAM, BUT, IF THIS IS NOT STEROID CREAM, MAYBE IT'S SAFE FOR HIM. ANY INFORMATION?
