Hello. I have what I believe to be a wheat allergy rash on my hands and arms. I have antihystamine tabs and cream for it, but wondered how long before it starts recovering. I first noticed it about 5 days ago but paid it little heed until it got worse. I started treating it today 6 july. Is there anything else I should be doing to aid recovery? Thank you.
Hello, True wheat allergy is rare, whereas wheat intolerance is quite common. Allergic rash secondary to wheat allergy is unusual, and this might be a coincidence. You are more likely to have idiopathic urticaria that might get worse after eating certain foods and long-acting antihistamines for 4-6 weeks is recommended. If you continue to have itchy rashes, continue for 3 months. Fexofenadine 180 mg/90 mg and/or cetirizine 10 mg is standard treatment options. I hope that was useful.
