Xyzal
"Within two days of starting this drug my Delayed Pressure Urticaria, DPU, came under control. It controls it so far to about at the 95% level. I had a couple of major flare-ups the first day I took it, but I suspect the levels had not built up in my blood yet. I have had one headache but unknown if this drug caused it.  My allergies are also under control. The Urticaria still appears a little but much less in size, scope and no itching or raised welts. No feelings of tiredness for me, in fact it kind of speeds me up. I'm amazed that a cousin of Zyrtec can do so much more. Zyrtec didn't touch the hives before, even when taking up to triple the normal daily dose. If you have hives give it a try."
