he takes it with his meds first thing in the morning and then again before bed with the rest of his meds. Some times he also takes it in the middle of the day if needed. usually twice a day does it. He has taken lower doses but the 0.06 works best

my husband has a script for "Ipratropiium Bromide nasal spray 0.06%" which seems to work - 2 sprays in each nostril and he can use it 3 times a day.

From https://www.apdaparkinson.org/article/rhinorrhe...

"Rhinorrhea is the technical term for runny nose. It literally means “fluid from the nose” and can refer to anything flowing from it. ... a nasal spray worked very well ... a patient who had fairly advanced Parkinson’s Disease said, “I can tolerate the problem with walking, but what really bothers me is that my nose is always running and it gets so bad when I eat that I can’t eat in front of anyone because it drips into my food.” A prescribed a nasal spray worked "

My nose drips constantly, it is clear, has no taste.

I take flonase quirts thru nose. mine doesn't run a lot but this prevents
a lot from happening.
