Loratadine
"I have chronic allergies (undiagnosed). I suffer from dry , red, stinging eyes and a nose that gets stuffy even with turbinate reduction surgery as well as general fatigue and low energy. Claritin helped me feel functional again and I can look people in the eye when I talk to them. Nose it a lot more clear. It is VERY important to take it for a week before it provides full relief. This did not start working for me till day 4 and now I feel great , perhaps the best ever. 

I am giving it an 8 because it causes me dry mouth and my sleep is not the greatest.

The point of this review is not to fully trust all the negative reviews. Try it for yourself every day for one , maybe even 2 weeks and see how it affects you. 

Best of luck."
