Interactions for Fluvoxamine
Drugs that are metabolized by and / or inhibit cytochrome P450 iso-enzymes: Plasma levels and/or pharmacodynamic effects of terfenadine, astemizole, cisapride, warfarin, theophylline, certain benzodiazepines and phenytoin should be monitored closely.
Monoamine oxidase inhibitors (MAOIs): It is recommended that fluvoxamine should not be used in combination with MAOIs or within 14 days of discontinuing treatment with a MAOI. After stopping fluvoxamine, at least 14 days should be allowed to elapse before starting a MAOI.
Benzodiazepines: Benzodiazepines metabolized by hepatic oxidation (e.g. alprazolam, midazolam, trizolam etc.) should be used with caution because the clearance of these drugs is likely to be reduced by fluvoxamine. Clearance of benzodiazepines metabolized by glucuronidation (e.g. lorazepam, oxazepam, temaxepam) is unlikely to be affected by fluvoxamine.
Diazepam: The co-administration of fluvoxamine and diazepam is generally not advisable because fluvoxamine reduces the clearence of both diazepam and its active metabolite.
Theophylline: If theophylline is coadministered with fluvoxamine, its dose should be redced to one third of the usual maintenance dose (as fluvoxamine decreases the clearence of theophyllline approximately 3-fold). No dose adjustment is required for fluoxamine.
Warfarin: Patients receiving oral anticoagulants and fluvoxamine should have their prothrombin time monitored and the anticoagulant dose adjusted accordingly.
Diltiazem: Bradycardia has been reported with the co-administration of fluvoxamine and diltiazem.
Propranolol and other beta blockers: If propranolol or metaprolol is co-administered with fluvoxamine, a reduction in the initial beta blockers dose along with cautious dose titration is recommended.
Typical Dosage for Fluvoxamine
Depression:Initial dose: 50 mg / day preferably at night dose can be increased by 50 mg every 4 - 7 days until sufficient response occurs. If the dose is more than 100 mg/ day, then the drug should be given in 2 divided doses.
Maximum dose: 300 mg / day
Schedule of Fluvoxamine
Storage Requirements for Fluvoxamine
Store at 15 - 30 degree C. Keep out of the reach of children. Protect from direct light and heat.
Effects of Missed Dosage of Fluvoxamine
Take the missed dose as soon as noticed and if it is the time for next dose then skip the missed dose. Continue the regular schedule. Do not double the dose.
Effects of Overdose of Fluvoxamine
Give supportive measures and symptomatic treatment. Drug can be removed from the body by inducing emesis or by gastric lavage Activated charcoal can be given to reduce the absorption of the drug.
