LUVOX is a prescription medication primarily used for the treatment of obsessive-compulsive disorder (OCD) and social anxiety disorder. As a selective serotonin reuptake inhibitor (SSRI), Fluvoxamine works by increasing the levels of serotonin, a neurotransmitter that plays a key role in mood regulation, in the brain. This helps to alleviate symptoms associated with anxiety and obsessive-compulsive behaviors.
