i started using nasonex approx 2 years ago i use it off and on for my allergies and i take claritin year round. every time i have used the nasonex i have had ridiculous head aches and anxiety attacks. i went with out using the nasonex for about 6 months and stayed the night with a friend that has a cat so i started using the nasonex again and now have white blisters all over the back of my throat. after reading these posts.......... the nasonex is now going in the trash! thank you all for making me aware of this. :D
