allergic urticaria
"My Doctor diagnosed me with dermatographia, and prescribed Singulair and Alavert.  The condition lessened, but did not go away.  I would still break out into hives on a daily basis, though they were not as frequent and covered a smaller portion of my body.  After a few months, she prescribed Vistaril in place of Alavert, and kept me on the Singulair.  Almost immediately, I noticed a significant change!  For the first time in months, I went an entire day without any hives - though I had to take the capsule four times a day.  If I took fewer capsules, my hives would come back.  I did experience severe drowsiness and a slight "euphoric" feeling, but it lessened over time."
