allergies
"I have severe allergies indoor and out. I cough constantly due to post nasal drip and irritated throat. I took Xyzal and within hours the coughing stopped! I ran out of pills and took Allegra. The coughing came back the same day. The coughing doesn't go down well with everyone being fearful of the Swine Flu! I am so thankful to have found Xyzal."
