Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain recurring itchiness all over the body including scalp and groin that is reduced with anti allergics like Levocetrizine and also having a history of
allergic reaction to wheat..
As you also have a pet dog at home itchiness can be due to allergic reaction or
Contact Dermatitis with animal danders..
For a permanent cure you first of all need a thorough evaluation and investigations like allergic tests like
Patch test, RAST test, Food Challenge test etc..
Once the exact cause of the allergic reaction is ruled out and you know the thing that is causing
allergy, avoiding exposure to the allergen and eliminating it from your environment can help in preventing recurring symptoms..
In case if you still get exposed accidentally anti allergics like Levocetrizine has to be taken..
The Allergist can also advise you
Immunotherapy that will be instilled gradually over the period of time and will help in reducing the severity and frequency of allergy symptoms..
Hope this information helps..
Thanks and regards.
