Compulsive hoarding
Obsessive-compulsive disorders are treated with various serotonergic antidepressants including the tricyclic antidepressant clomipramine and various SSRI medications. With existing drug therapy, OCD symptoms can be controlled, but not cured. Several of these compounds (including paroxetine, which has an FDA indication) have been tested successfully in conjunction with OCD hoarding.
Fluvoxamine
Fluvoxamine's only FDA approved indication is in the treatment of OCD, although in other countries (e.g. Australia, the UK, and Russia) it also has indications for major depressive disorder. In Japan it is currently approved to treat OCD, SAD and MDD. Fluvoxamine is indicated for children and adolescents with OCD. The drug works long-term, and retains its therapeutic efficacy for at least a year. It has also been found to possess some analgesic properties in line with other SSRIs and tricyclic antidepressants.
