I have been lurking here for several months. I read a whole lot but do not post. My liitle boy has aspergers syndrome and is taking Risperdal and taking concerta for ADHD. I was wondering if Risperdal would make his prolactin levels go up. He is 8 years old and the doctor now wants him to have an MRI done. His prolactin level is 23.8. Anyone ever had this problem.
