Every little bit does help. Your bedroom
for sure! I also take singulair. I dont know
what Qvar80
is. I take a lot of medication. Singulair, Advair, Flonase, and Allegra. When I get a sinus headache I also take Allegra D. I started getting allergy shots too. Im allergic to mold too. Have someone clean it or remove it if possible (within your financial means).Wear a mask when you have to be around it. All of this is extreme and a lot of work.
