Fluvoxamine

Fluvoxamine, sold under the brand name Luvox among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is primarily used to treat major depressive disorder and, perhaps more especially, obsessive–compulsive disorder (OCD), but is also used to treat anxiety disorders such as panic disorder, social anxiety disorder, and post-traumatic stress disorder. Fluvoxamine's side-effect profile is similar to that of other SSRIs. Common adverse effects include constipation, gastrointestinal problems, headache, anxiety, irritation, sexual problems, dry mouth, sleep problems, and an increased risk of suicide at the start of treatment. These effects appear to be significantly weaker than with other SSRIs, with the exception of gastrointestinal side-effects. In some patients, sexual dysfunction may persist even after the drug is discontinued, a condition known as post-SSRI sexual dysfunction; regulatory agencies including the European Medicines Agency and Health Canada have recommended that fluvoxamine's product labeling warn of this risk. Fluvoxamine appears to be more tolerable than other SSRIs, particularly with respect to cardiovascular complications. It is on the World Health Organization's List of Essential Medicines.
