<s>[INST] Hi, I am a female, age 22, in great health. I have never had any allergies my entire life, nothing at all. Tonight my face has turned bright red, slightly splotchy and very very hot...seemingly an allergic reaction. I cannot identify what or if it is potentially serious. Besides the face I have no other symptoms.  I was drinking a glass of wine when this started. I have never had a problem with wine before, but have read different levels of sulfates in wine can cause reactions... [/INST] Hello,Yes, the older the wine the more reactions one can have if they have intolerance to sulphites that is present in all wines.This is usually a self limiting reaction unless you feel short of breath which happens in people with underlying asthma, and they need to be more careful.Sulfite-free diet is not recommended, as non-sedating antihistamines will work.Best Wishes. </s>
