Dose reference
Human
Adults: The recommended starting dose for Fluvoxamine Maleate Tablets in adult patients is 50 mg, administered as a single daily dose at bedtime. In the controlled clinical trials establishing the effectiveness of Fluvoxamine Maleate Tablets in OCD, patients were titrated within a dose range of 100 to 300 mg/day. Consequently, the dose should be increased in 50 mg increments every 4 to 7 days, as tolerated, until the maximum therapeutic benefit is achieved, not to exceed 300 mg per day. It is advisable that a total daily dose of more than 100 mg should be given in two divided doses. If the doses are not equal, the larger dose should be given at bedtime.Pediatric Population (children and adolescents): The recommended starting dose for Fluvoxamine Maleate Tablets in pediatric populations (ages 8-17 years) is 25 mg, administered as a single daily dose at bedtime. In a controlled clinical trial establishing the effectiveness of Fluvoxamine Maleate Tablets in OCD, pediatric patients (ages 8-17) were titrated within a dose range of 50 to 200 mg/day. Physicians should consider age and gender differences when dosing pediatric patients. The maximum dose in children up to age 11 should not exceed 200 mg/day. Therapeutic effects in female children may be achieved with lower doses. Dose adjustment in adolescents (up to the adult maximum dose of 300 mg) may be indicated to achieve therapeutic benefit. The dose should be increased in 25 mg increments every 4 to 7 days, as tolerated until the maximum therapeutic benefit is achieved. It is advisable that a total daily dose of more than 50 mg should be given in two divided doses. If the two divided doses are not equal, the larger dose should be given at bedtime.Elderly or Hepatically Impaired Patients: Elderly patients and those with hepatic impairment have been observed to have a decreased clearance of fluvoxamine maleate. Consequently, it may be appropriate to modify the initial dose and the subsequent dose titration for these patient groups.

The exact mechanism of action of fluvoxamine has not been fully determined but appears to be linked to its inhibition of CNS neuronal uptake of serotonin. Fluvoxamine blocks the reuptake of serotonin at the serotonin reuptake pump of the neuronal membrane, enhancing the actions of serotonin on 5HT1A autoreceptors. Studies have also demonstrated that fluvoxamine has virtually no affinity for α1- or α2-adrenergic, β-adrenergic, muscarinic, dopamine D2, histamine H1, GABA-benzodiazepine, opiate, 5-HT1, or 5-HT2 receptors, despite having an affinity for binding to σ1 receptors.
Drugs Inhibiting or Metabolized by Cytochrome P450: Fluvoxamine inhibits several cytochrome P450 isoenzymes (CYP1A2, CYP2C9, CYP3A4, and CYP2C19). Carbamazepine: Elevated carbamazepine levels and symptoms of toxicity with coadministration (7.2). Sumatriptan: Rare postmarketing reports of weakness, hyperreflexia, and incoordination following use of an SSRI and sumatriptan. Monitor appropriately if concomitant treatment is clinically warranted. Tacrine: Coadministration increased tacrine C max and AUC five- and eight-fold and caused nausea, vomiting, sweating, and diarrhea.Tricyclic Antidepressants (TCAs): Coadministration significantly increased plasma TCA levels. Use caution; monitor plasma TCA levels; reduce TCA dose if indicated. Tryptophan: Severe vomiting with coadministration.Diltiazem: Bradycardia with coadministration.Propranolol or metoprolol: Reduce dose if coadministered and titrate more cautiously
Most common reactions in controlled trials with adult OCD and depression patients (incidence ≥5% and at least twice that for placebo) were nausea, somnolence, insomnia, asthenia, nervousness, dyspepsia, abnormal ejaculation, sweating, anorexia, tremor, and vomiting. Using the above rule, the following events were also identified: anorgasmia, decreased libido, dry mouth, rhinitis, taste perversion, and urinary frequency in patients with OCD; and agitation, depression, dysmenorrhea, flatulence, hyperkinesia, and rash in pediatric patients with OCD.
Consider both potential risks and benefits when treating a pregnant woman. Infants exposed to SSRIs late in pregnancy have developed various complications and may be at risk for persistent pulmonary hypertension of the newborn (PPHN). Fluvoxamine is secreted in human breast milk.
Fluvoxamine Maleate should be used with caution in patients with a history of mania, seizures, suicide, concomitant ECT, cardiac disease, diabetes mellitus, angle-closure glaucoma, history of bleeding disorders (especially gastrointestinal bleeding), hepatic and renal impairment. Fluvoxamine maleate may also impair the performance of skilled tasks (driving).
