I have to spray the nebulizer version of Budesonide (Pulmicort Respules) up my nose to combat my allergies - regular nasal steroid sprays don't do anything for me. This is in addition to nebulizing the Budesonide, and using Claritin daily. Claritin doesn't clear up my nose either unless I take 10mg every 6 hours. You might consider asking your doctor about increasing your Zyrtec, and if an H2 histamine blocker such as Zantac would help (some allergy symptoms can be from type 2 histamines in addition to or instead of type 1 histamines; Zyrtec & other related antihistamines commonly used for allergies only block type 1 histamines). I too can smell dust, have been able to for years. I can't do the allergy shots either because my immune system is too compromised. Allergies suck!
