It seems that your urticaria
is truly idiopathic in nature, but I presume that the H pylori test (during endoscopy
) was negative as your results of food allergies.
Thyroid function with TPO antibodies
should be checked as occasionally thyroid imbalance can be the cause.
You will need Allegra 180mg AM plus 90mg PM and cetirizine
10mg (midday) with 10mg reserve at night (PM) or hydroxyzine
25/50mg ONLY at night to control the urticaria. There are various combinations of antihistamines you can use that give you best control. Anti-IgE therapy (Omalizumab) or high-dose IVIG are expensive traetment options especially when hydroxycholoroquine or ciclosporin fails after antihistamines have not worked.
