I was just told about the 9/2/09 approval of Astepro 0.15% nasal spray for the treatment of seasonal allergic rhinitis and perennial allergic rhinitis. Currently Astepro 0.30% nasal spray is already approved. Technically the 0.15% can be dosed once daily versus the 0.30% dosed twice daily. These seem to me to be the only differences. Honestly, I'm not too excited. This is a lower strength product that has been approved for providing relief for a longer period of time. If the same studies were done with the 0.30%, once daily dosing might have been approved too. Marketing will begin soon. There are no comparative trials. The peak of the weed season historically is today. If you have symptoms, please follow the normal, proven game plan. Educate yourself, reduce your exposure, take all meds as directed, and if you don't get relief, then consult with your physician. If you still don't get relief, then find yourself an "Allergy Dude" like me.
