If you can stand shooting stuff up your nose, the spray works great. It made my nose run for about 5 minutes after spraying before it started to clear up. Works great for stuffy noses, especially those caused by a cold or the flu. It did not work as well on my allergies, however. I could breathe for about 30 minutes before my running nose came back.
