Obsessive-compulsive disorder (OCD) is often treated with antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs). These drugs help to increase the levels of serotonin in the brain, which can reduce symptoms such as compulsive behaviors and anxiety. Vitamins, steroids, and analgesics are not typically used to treat OCD.
