I got severe itching on skin all over body. This happens many times during the year. I am also suffering from major depression and any anti allergic like cetrizine levocetrizine atarax etc induce too much sleep drowsiness rendering me not functional for 24 hours after taking them. Only allegra 180mg is non drowsy but does not work that much. Many times i take twice of it three times a day to control itching as feel helpless. Am on diabetes medication as well. Are there really medicines which can help being non drowsy in my case? Without too much complications.
