Hi, I am suffering from allergic rhinitis from 2006, i am taking allercet tablets when I need, sometimes I use flomist nasal spray but it is not effective sometimes, my question is are there any side effects in long term usage of allercet tablets, is there any alternate treatment or surgery? Not able to lead a normal life , early morning when I wake up I usually start sneezing with runny nose itchy red eyes, when I take allercet I feel drowsy and sleepy, kindly help
