###Human: I am taking Celexa and Xanax for OCD without any improvement. Should I change my treatment? ###Assistant: Hi. Please mention about your OCD (obsessive-compulsive disorder) symptoms. Please say about the type of obsessions and compulsions you have. You can take tablet Prozac (Fluoxetine) 20 mg for a week and gradually increase it to 40 mg. Prozac helps for OCD as well as for impulsivity. Along with it, take tablet Olanzapine 10 mg. It helps for the current mood stability you are experiencing now. Also, consider going to therapy such as exposure and response prevention. It also helps for OCD.
