Yes Xylar is a nasal spray. It was advised for me because of sinusitis.
OOOPS!!!!, the right name is XLEAR. It is made with XYLITOL????
It is not sell out in pharmacies, you must google the name and will find out where to buy it. Only over the internet.
I don't write down where I bought it because will be a moderator that will delete the link, because of forum rules.
As I said it didn't work for me but it worked for my wife. Once more, we are all different.
I hope it will work for you too.
