[|Human|] 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.
[|AI|]  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.
