Urticaria
"I took xolair for chronic idiopathic urticaria, the hives disappeared after the first injection. The 3 first months was 300mg per 4 weeks. After 3 months the hives came back&hellip; reactine, and blexten ( new antihistamin) can&#039;t do anything for my hives. The doctor increase my xolair to 300mg per 2 weeks. The hives completely disappeared but, after the injections I have headaches for 3-4 days and I&#039;m so tired. But for the moment is more acceptable that have hives and angioeodema ! ( sorry my english is bad)"
