How does this medication work? What will it do for me?
Fluvoxamine belongs to the class of medications called selective serotonin reuptake inhibitors (SSRIs). It is used to treat depression and obsessive-compulsive disorder (OCD). It helps to reduce anxiety and unpleasant thoughts associated with OCD and improves mood by treating depression.
Serotonin reuptake inhibitors are thought to work by increasing the amount of a neurotransmitter (a chemical found in the brain) called serotonin. Although you may start feeling better within a few weeks of treatment, the full effects of the medication may not be evident until several weeks of treatment have passed.
