Has anyone ever taken prozac and risperdal together?

My doctor prescribed me prozac and risperdal for my ocd. (I have trichotillomania) When I search online it says there is a reaction between the two when taken together. Even when I picked them up from the pharmacy the pharmacist asked me what i was on risperdal for and he was wary about giving it to me. I am on 80 mg of prozac and have been since may. If anyone has taken them together, did you have any side effects?
