Which SSRI is approved for treating obsessive-compulsive disorder?

Paroxetine is an SSRI (selective serotonin reuptake inhibitor) that has received approval for the treatment of obsessive-compulsive disorder (OCD). SSRIs like paroxetine work by increasing the levels of serotonin in the brain, which can help alleviate symptoms of OCD, characterized by unwanted and intrusive thoughts and repetitive behaviors.

Paroxetine's efficacy in treating OCD has been supported by various clinical studies, demonstrating its ability to reduce the severity of obsessions and compulsions. This makes it a valuable option for patients suffering from OCD, providing them with a mechanism to manage their symptoms effectively.

The other medications listed do not have this specific approval for OCD treatment. Desipramine and amitriptyline are tricyclic antidepressants that are not first-line treatments for OCD, whereas selegiline is primarily used for Parkinson's disease and has no established role in managing OCD symptoms.
