There are biologicals like omalizumab which are now available for urticaria (injections that target only the cells causing allergy and do not affect other cells or chemicals in the body). If you know something like egg is causing it avoid it. Antihistamines like hydroxizine (atarax) are usually quite effective and biological medicines are reserved for difficult cases not responding to standard materials. An allergy testing for common food and inhalational allergens may help you. It can identify things causing the allergy. A lot of allergic problems are due to the immune system being hyper responsive. Daily exercise, breathing exercises like pranayama do help in correcting these on a long term basis and improving the immune system. Warm regards. Dr. Rajdeep Mysore. Chirag Hospital Bangalore.
