<s>[INST] I recently purchased some organic chocolate milk with alkaline cocoa in it.  My 3 1/2 year old has been drinking milk her entire life without issue...but since she started drinking this, she has broken out in a red rash on her face and arm.  The rash on her arm went away fairly quickly, but the rash on her face still persists.  It did get better overnight, but when she drank more chocolate milk, it became worse again.  It doesn't seem to bother her at all, but it is dry and red.  If she has no other issues with milk, can she be allergic to something in the chocolate milk (she has had chocolate syrup in milk many times with no issues either).  This is the only think we have changed in our daily routine.  Thank you so much! [/INST] Hello,Thank you for asking at HCM.I went through your history and would like to make suggestions for your daughter as follows:1. From your history, I would first think of allergic reaction to some substance within the organic chocolate milk. However, it is difficult to determine exactly which component within the chocolate milk as there are so many constituents including milk, chocolate, cocoa, sweeteners, preservatives, coloring agents, etc etc.2. I usually suggest my such patients to stop consuming the thing that caused allergic reaction and taking an antihistamine like hydroxyzine or cetirizine would control itching and rash.Hope above suggestions will be helpful to you.Should you have any further query, please feel free to ask at HCM.Wish your daughter the best of the health ahead.Thank you & Regards. </s>
