Pharmacologic class: Selective serotonin reuptake inhibitor (SSRI)
Therapeutic class: Antidepressant, antiobsessive agent
Pregnancy risk category C
Selectively inhibits serotonin reuptake in neurons. This inhibition is thought to relieve depression and reduce behaviors related to obsessive-compulsive disorder (OCD).
Capsules (extended-release): 100 mg, 150 mg
Tablets: 25 mg, 50 mg, 100 mg
⊘Indications and dosages
Adults: Initially, 50 mg P.O. daily at bedtime; may increase by 50 mg q 4 to 7 days until desired effect occurs (not to exceed 300 mg/day). If daily dosage exceeds 100 mg, give in two equally divided doses; if doses aren't equal, give larger dose at bedtime. As needed, adjust dosage periodically to maintain lowest effective dosage that controls symptoms (immediate-release formulation)
Children ages 8 to 17: Initially, 25 mg at bedtime; may increase by 25 mg/day q 4 to 7 days until desired effect occurs (up to 200 mg/day for patients up to age 11 or up to 300 mg for adolescents). If daily dosage exceeds 50 mg, give in divided doses, with larger dose at bedtime (immediate-release formulation).
➣ OCD; social anxiety disorder
Adults: 100 mg P.O. once daily at bedtime; titrate in 50-mg increments weekly, to a maximum of 300 mg/day (extended-release formulation).

Drug-behaviors.Smoking: decreased fluvoxamine efficacy
☞ Watch closely for signs and symptoms of depression and suicidal ideation (especially in child or adolescent).
• Assess patient's appetite. Report weight gain or loss.
• Monitor liver function test results.
• Monitor cardiovascular status, particularly blood pressure.
• Instruct patient to swallow extended-release capsules whole and not to break, crush, or chew them.
☞ Instruct patient or caregiver (especially with child or adolescent patient) to recognize and immediately report signs of suicidal intent or expressions of suicidal ideation.
• Inform patient that drug may take several weeks to be fully effective.
• Recommend establishing effective bedtime routine to minimize insomnia.
• Instruct female patient to notify prescriber if she becomes or intends to become pregnant. Caution her not to breastfeed.
