What's a good NON-PRESCRIPTION nasal allergy medication...?

NONE, they are temporary fixes that create other problems shortly later. I suggest a natual remedy they sell where you use natural product with a tea type cup with a nose spout. Havent tried it but I guess you get good results. Just do research online. Of all the Over the counter products I used for my nose Afrin was the best just so you may know but creates other problems of dry throat and nose irritation later in the day.

claritin d is super good for allergies and it may make you tired but if you take it long enough it dosen't and if it bothers you take it before you go to bed since its a 24 hour pill. I live in florida where i am allergic to every plant pollen there is here but my number one allergy is dust so i know this will help you

Try nasonex. Its a spray that is used up the nose. Another might be benydril allergy

I know this will sound weird, but you may want to purchase roobois tea, red tea (kalahari is a good brand). A recent japanese study found that it can decrease allergies, and i use it to help ease dander and mold allergies. It has no caffeine, and works if you drink it in the morning and at night.
