I'm allergic to everything. The worst symptom is the dropping nose. I tried many things but the combination cetirizina - dymista-keftofil is the only thing that works for me. I use cetirizina for 10 days and I rest for 7 days (for at least a year). I use keftofil only if I feel I need it but I do not know if I have to use dymista all year without stopping. I've noticed that if I do not use it my nose starts to drop again. I can not meet my doctor that's why I'm asking here. Thank you very much for your help.
