jennyHi,
My SWCAH 8yrs old also takes Flonase. I was also worried about it when I read the info on it. I called the ENT & his endo. They both agreed it was fine! He has been using it for almost a year now. We have had a couple of labs and everything is ok. It does really help. He is going to have surgery to remove his adenoids and hopefully he will no longer need the flonase.
