Allergic Rhinitis
"Clarinex is absolutely wonderful when it comes to treating allergic rhinitis, itching, sneezing, rash, asthma like feeling. However lately I&#039;ve been getting skipped heart beat feeling and lightheadedness after taking it for 2 years now. I&#039;m guessing it&#039;s due to Clarinex since I&#039;m not taking any other medicines other than an occasional Biotin tablet."
