I never use to have nasal allergies until I started getting older. Now, my nose is pretty much sensitive to everything. The worst part is when I get really congested with scratchy, itchy eyes and a raging headache on top of it! I can kind of deal with the stuffiness and the itchy part, but let me tell you, the headaches kill me! I've tried so many things over the counter and so far nothings worked for me, until I tried Advil Allergy Sinus. As severe as mine get sometimes, with sensitivity to light and sound as well, two caplets of this stuff will help knock it right out, and make my other symptoms feel so much better too. It has Ibuprophen for pain, Pseudoephedrine HCl as a decongestant, and Chlorpheniramine Maleate as a antihistamine. I have tried acetaminophen based over the counter meds, but for me nothing works on the pain like ibuprophen. So if you have tough nasal allergies and headaches, and hadn't tried this, I suggest you do. You might be pleasently surprised!
