allergic urticaria
"I was diagnosed with Urticaria at the age of 16 (in 1985 which just came out of the blue) and took an Atarax pill every 3-4 days when I felt the itchiness coming on. It worked 100%. Later in life they suggested I try some other antihistamine (Claritin), which I did and it worked but I have to take a pill every day so I went back to Atarax as I did not suffer from drowsiness (after taking it for so many years). Fortunately in 2011 the Urticaria disappeared and I no longer need any meds for it. If ever I get itchy skin again, Atarax will be my choice."
