http://www.medications.com/effect/view/20381 Two weeks ago I started Flonase.After the first day I became achy all over. Thought I had the flu. On the third day of using it I wasn't able to sleep. I was restless, nervous. I believe it may have interacted with my Zyrtec that I take for chronic hives.

I've found that when I use it regularly, it basically "relocates" my congestion from my nose to my throat, causing me to have a sore throat. http://www.medications.com/effect/view/20381?item=4114
