Urticaria
"My husband got a very acute urtricaria on his whole body for 2 weeks. Nothing helped really to get rid of the burning patches. Benadryl caused more drowsiness then any help and additionally my husbands face was sweeling all over when taking Benadryl. Finally we got Allegra 180 mg pills. And just after the first Allegra pill all red patches on his skin and all swollen areas were gone for good as long as he keeps taking it twice a day 180 mg each tablet. This medicine is really great."
