I had a bit of nasal involvement with disease onset. The pulmonologists on the team that dxed me suggested taking 10 mg/day of loratidiene and 2x10 mg/day of phenylephrine. I've been doing this since dx. The only time I have a runny nose is when I have a cold. A benefit I didn't expect is that I no longer have hay fever or an allergic reaction to animal dander.
I do sinus rinses when the air is very dry or when I have a cold. I also use a special nasal cream from Cleveland Clinic to keep the crusting to a minimum.
