I had been diagnosed with Acute Urticaria about a month back. Was prescribed Allerga and another anti-allergy tab. Took that for 2 weeks but it did not help. Saw a doctor after 2 weeks and he prescribed a higher dosage of both Allegra as well as Bilastine, that did not help either as i tried it for another 3-4 days. Finally the doctor prescribed Wysolene among other medicines like pan-40, xyzal and dazit. This worked. However my medicine got over yesterday after 2 weeks' dosage and we're back to the urticaria reappearing. I also underwent tests like IGE, CBC and Kideny tests and all of them turned out to be alright and the doctor said in 80% cases it's hard to detect the allergen for urticaria. Kindly HELP.
