Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. For some people, celiac disease causes an itchy, blistering rash known as dermatitis herpetiformis. The rash usually clears with a gluten-free diet but can also be treated with medication. You can also use antihistamines daily to relief the itching and use calmine lotion for local relief. Hope I have answered your query. Let me know if I can assist you further.
