Luvox CR Dosage

Generic name: FLUVOXAMINE MALEATE 100mg
Dosage form: capsule, extended release
Drug class: Selective serotonin reuptake inhibitors

Medically reviewed by Last updated on Dec 26, 2023.

OCD (Obsessive Compulsive Disorder)

The recommended starting dose is 100 mg at bedtime, with weekly increases of 50 mg as tolerated to maximum therapeutic benefit, not to exceed 300 mg per day.

Capsules should not be crushed or chewed.

Pediatric Patients Naïve to Fluvoxamine Maleate

Physicians should consider that the lowest available dose of LUVOX CR Capsules may not be appropriate for pediatric patients naïve to fluvoxamine maleate.

Dosage for 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 titrate slowly following the initial dose of 100 mg in these patient groups.

Maintenance/Continuation of Extended Treatment

Although the efficacy of LUVOX CR Capsules beyond 12 weeks of dosing has not been documented in controlled trials, OCD is a chronic condition, and it is reasonable to consider continuation for a responding patient. The benefit of maintaining patients with OCD on immediate-release fluvoxamine maleate tablets after achieving a response for an average duration of about 4 weeks in a 10-week single-blind phase during which patients were titrated to effect was demonstrated in a controlled trial (see CLINICAL TRIALS [14.2]). Dosage adjustments should be made to maintain the patient on the lowest effective dosage, and patients should be periodically reassessed to determine the need for continued treatment.

Switching a Patient To or From a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders

At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with LUVOX CR Capsules. Conversely, at least 14 days should be allowed after stopping LUVOX CR Capsules before starting an MAOI intended to treat psychiatric disorders (see CONTRAINDICATIONS [4.1]).

Use of LUVOX CR Capsules with Other MAOIs such as Linezolid or Methylene Blue

Do not start LUVOX CR Capsules in a patient who is being treated with linezolid or intravenous methylene blue because there is an increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization, should be considered (see CONTRAINDICATIONS [4.1]).

In some cases, a patient already receiving LUVOX CR therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risks of serotonin syndrome in a particular patient, LUVOX CR should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for two weeks or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with LUVOX CR may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue (see WARNINGS AND PRECAUTIONS [5.2]).

The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with LUVOX CR is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use (see WARNINGS AND PRECAUTIONS [5.2]).

Discontinuation of Treatment with LUVOX CR Capsules

Symptoms associated with discontinuation of other SSRIs or SNRIs have been reported (see WARNINGS AND PRECAUTIONS [5.10]). Patients should be monitored for these symptoms when discontinuing treatment. A gradual reduction in the dose rather than abrupt cessation is recommended whenever possible. If intolerable symptoms occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered. Subsequently, the health care provider may continue decreasing the dose but at a more gradual rate.
