Yes it would: But if it doesn't or you need more medicines to control your symptoms, please see your doctor, read the instructions carefully

Perhaps: Antihistamine alone often does not work well enough for nasal symptoms particularly congestion. For many people , a once daily pill is insufficient. As for hives, most people will need taking a 24-hr antihistamine 2-4 x daily to control the hives.
