I have a seven year old daughter with chronic asthma. A year and a half ago she was placed on Singulair which was a Godsend, however we moved a year later and after moving into the new house her condition declined rapidly. She was then placed on Zyrtec and once again she is great. My concern is that with winter coming(when she typically is at her worst), will she still be great? Is anyone on these two meds and how have they been long term, seasonal changes etc...?
