Clarinex Reviews

For Allergic Rhinitis "Clarinex is absolutely wonderful when it comes to treating allergic rhinitis, itching, sneezing, rash, asthma like feeling. However lately I've been getting skipped heart beat feeling and lightheadedness after taking it for 2 years now. I'm guessing it's due to Clarinex since I'm not taking any other medicines other than an occasional Biotin tablet."


For Allergic Rhinitis "I was in a study of this drug at Emory University and finished the study. I have severe allergies, and I knew immediately when I did NOT get the placebo. I am so lucky I got the Clarinex. It worked well and the only side effect I got and reported was that I became very dry in my nose and throat. I am trying to be prescribed it now, as nothing over the counter is working. Unfortunately, my current GP said he had never heard of it. This is the most effective day time antihistamine I've ever had."


For Allergic Rhinitis "I took my first Clarinex 5mg 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."


For Urticaria "I have the 'fast heartbeat', but is much better to deal with than the refractory hives I have. Only Doxepin and Clarinex abate the itching."


For Allergic Rhinitis "It seems to be helping pretty quick. An hour and half later I have the side effects of dry mouth and extreme tiredness."


For Allergic Rhinitis "Great relief. Other ones make me sleepy."
