Nasal Congestion
"I took Claritin D this morning because of severe nasal congestion, it was relieved after few hours but the side effects is not good, I can&#039;t sleep. I am so tired and want to rest but I am still wide awake until 1am. How I wish, I read the reviews first before taking it..so no more Claritin D...I will go back to Allegra."
