zyrec is not recommended for children in your childs age group. your doctor should have never prescribed it to begin with. if its not helping the child, then stop giving it to her. more then likely, your doctor prescribed it to her because the pharmacy rep. gave him a big check as a incentive to prescribe it to as many people as possible. if the childs sniffles are worse as she is going to bed, then more then likely it is the bedding that is causing it. what to do..simple, take everything off the bed, sheets, blankets, pillows, toys, the dog, everything.then wash absolutely everything in hot water with baking soda, no detergent. get rid off the feather pillows, no dog or cat sleeping in room with the child, and then tackle the room, steam clean the rugs, and wash the curtains and wipe down the bed frame, throughly.any questions, email me..
