My Grand Daughter has been on Concerta since March w/great success noticed by family & teachers. However, as it started getting hotter this June &/or being out in sun (sometimes only sun, sometimes only heat indoors @ gymnastics) more we noticed she is turning red & itching on different parts of her body, (cheeks, upper arms, thighs, chest, back, etc.) not necessarily all at once. Is this a common side effect? She's 12 & never had this problem before now. She has Asthma & other meds she is on are Advair, Singulair, Zyrtec & Protonix for her reflux.
