allergies
"After taking everything else and still having same problems in decided to take levocetirizine 5 mg just to make my doctor happy. It worked miracles! 7 years of no hives, no sneezing,  no itchy eyes during worst pollen season nothing!  (My biggest problem is dust mite, so I take this medication through the whole year) but everything must come to an end. Blue cross Blue shield is no longer paying for this medications, it will cost me $76 for 30 pills.  So I am now trying to find anything that's close to levocetirizine but no luck. All my symptoms returned overnight."
