###Human: Kindly suggest treatment for urticaria. ###Assistant: Hello. You have new-onset urticaria. Since it has gone on for longer than six weeks, it is now considered chronic urticaria. It is a common condition. Most people will experience at least one episode of urticaria during their lifetimes. There are many causes of urticaria such as 1. Infections-viruses, bacteria, and parasites 2. Drug allergies. 3. Food allergies. 4. Insect bites or stings. 5. Physical causes like exposure to cold. The exact cause cannot be identified in about 50 % of the cases. Please try to see if you have changed any cosmetics (hair dye, creams, powders, soaps, shampoos, deodorants, etc.). Have you started any new medicine or supplements (including herbal, over-the-counter, etc.)? Any recent change in your occupation, use of latex, etc. Any urine infection-burning urine etc. Any use of food colors?If no answer can be obtained, I suggest checking a complete urine examination. Also, I would try a course of de-worming treatment. Albendazole chewable tablets (brand name Zentel) 400 mg. Take it in two doses. The first and second dose should be separated by a week. Take after food, only two doses are required. For symptom relief, try antihistamines. I suggest a non-sedating anti-histamine taken once a day in the morning.If this alone helps, fine, if not, take a different antihistamine at night. Take them daily for a few weeks and then start cutting back slowly and observe. If your itching and urticaria do not respond to anti-histamines, you may need to take corticosteroids.
