For Allergic Rhinitis "The first day it was effective, but I started to feel tired and sad. I also suffered from lack of sleep and felt thirsty all the time, even though I drank lots of water. I was not able to do number 2 :-) for 3 days, and I had stomach aches. I stopped taking this drug immediately."

For Allergic Rhinitis "I took Claritin for congestion due to allergies. Day 1, I felt a bit tired after taking it, but the congestion began to clear. Day 2, I felt fine for a few hours with the exception of dry mouth, all of a sudden, I became severely dizzy and felt like I was going to fall out of my chair. Checked all my vitals: BP, oxygen, sugar, etc., and they are perfect. The only new medicine I took was Claritin. I am lying on my back right now, writing this review while I am recovering from the effects."

For Allergic Rhinitis "This stuff did very little for my allergies. It made me feel tired and spaced out and gave me minor heart palpitations. Benadryl works much better but has some dangers if taken long term. Nasacort has few side effects for me but only limited help. Some homeopathic nasal sprays work better than most OTC stuff."
