Clear with no side effects
I've been using this XLEAR nasal spray for over four years, as needed, for sinus congestion caused by allergies. This works great with absolutely no side effects for me. I've recommended it for pilot friends who can use this and still fly because it has no side effects. I also use XLEAR at first sign of cold, flu, or virus, and it keeps congestion at bay. No sinus infections either since I quit all allergy meds (prescribed meds and over counter meds) and began using xlear.
Great for allergy relief
I use this at night and it works great to keep my nose clear so I can actually breathe all night.
