All drugs are used for treatment of OCD except:: (A) Carbamazepine, (B) Lithium, (C) Fluoxetine, (D) Diazepam
Answer is D. Again, we have to choose between Carbamazepine and diazepam. Now, diazepam is a benzodiazepine and can improve anxiety temporarily however it doesn't act at core symptoms of OCD. Whereas, Carbamazepine, though has minimal evidence, but it has been found to act on core symptoms of OCD.
