For Allergic Rhinitis "I tried it as I got it on sale at Shoppers 70 pack. What a mistake - 2 1/2 hours before any signs of it working (Aerius). It did not relieve symptoms, especially itching and runny nose. I felt like I was drugged (not myself) - felt tired and had to lay down. I tried it several times and still not happy. It did not last 24 hours and I only felt some relief 12 to 18 hrs. in. It does not do what it says on the package so I switched back to Reactine. Even though it is a generic antihistamine - no problems and I got the effects within 1/2 hr. and all symptoms gone. I was not drowsy or dopey and 24 hr relief. Nice try Bayer, but you have a dud on your hands - will never buy it again. Anyone want 60 freebies?"

For Allergic Rhinitis "I’m very sensitive to any types of medications. Although it did take away my allergy symptoms, it caused me the most insane anxiety that I had to leave work. My heart was racing, shaking, stomach upset, loss of appetite, tiredness, yet I felt zapped at the same time."

Desloratadine for Allergic Rhinitis "I took my first Clarinex 5 mg 3 hours ago. I'm nauseous, lightheaded, shaky, and tired. I'm calling my doctor to tell him I can't take it. I can't wait for it to be out of my system."

Desloratadine for Allergic Rhinitis "It seems to be helping pretty quickly. An hour and a half later, I have the side effects of dry mouth and extreme tiredness."
