The non medication would be a Netty pot with sterile water. It will decrease the pollen burden on your sinuses. On the herbal side options include local honey, but this is theoretical. The idea being that the lower dose of exposure may work to decrease the immune reaction.
I personally use Claratin and zyrtex. I was using Flonase. Now I'm switching to rhinocort.
Thank you, will due the betty pot soon. I took some Benadryl but it has only made me sleepy instead of any better.
I don't know where you live, but here raw, local honey is a big thing and it helps me so much with allergies. I just eat a spoonful several times a day.
