Fluvoxamine is used to treat obsessive-compulsive disorder (OCD). It helps decrease persistent/unwanted thoughts (obsessions) and urges to perform repeated tasks (compulsions such as hand-washing, counting, checking) that interfere with daily living. Fluvoxamine belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs). This medication works by helping to restore the balance of certain natural chemicals (neurotransmitters such as serotonin) in the brain.

Read the Medication Guide provided by your pharmacist before you start using fluvoxamine and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth with or without food, usually once daily at bedtime, or twice daily, or as directed by your doctor. Dosage is based on your medical condition and response to therapy. For children, the dosage may also be based on their age and gender. To reduce your risk of side effects, your doctor may start you at a low dose and gradually increase your dose. The maximum recommended daily dose is 300 milligrams for people aged 12 years and older and 200 milligrams for children up to 11 years. Doses greater than 100 milligrams in adults or 50 milligrams in children should be given as 2 equally divided doses. If the doses are not equal, then the larger dose should be given at bedtime. Consult your doctor or pharmacist for more details. Avoid eating grapefruit or drinking grapefruit juice while being treated with this medication unless your doctor instructs you otherwise.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: personal or family history of psychiatric disorder (e.g., bipolar/manic-depressive disorder), personal or family history of suicide attempts, liver disease, seizures, low sodium in the blood, stomach/intestinal ulcers. This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Avoid alcoholic beverages. Liver function declines as you grow older. This medication is removed by the liver. Therefore, elderly people may be at greater risk for side effects while using this drug. The elderly are also more likely to develop a type of mineral imbalance (hyponatremia), especially if they are also taking "water pills" (diuretics) with this medication. Caution is advised when using this drug in children because they may be more sensitive to the side effects of the drug, especially loss of appetite and weight loss. It is important to monitor weight and growth in children who are taking this drug. Use this medication only when clearly needed during pregnancy. It may harm an unborn baby. Also, babies born to mothers who have used this drug during the last 3 months of pregnancy may infrequently develop withdrawal symptoms such as feeding/breathing difficulties, seizures, muscle stiffness, or constant crying. If you notice any of these symptoms in your newborn, tell the doctor promptly. Since untreated depression can be a serious condition, do not stop taking this medication unless directed by your doctor. If you are planning pregnancy, become pregnant, or think you may be pregnant, immediately discuss the benefits and risks of using this medication during pregnancy with your doctor.

Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first. This drug should not be used with the following medications because very serious interactions may occur: alosetron, cisapride, diazepam, pimozide, ramelteon, sibutramine, thioridazine, tizanidine. Avoid taking MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) within 2 weeks before, during, and after treatment with this medication. In some cases a serious, possibly fatal drug interaction may occur. If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting fluvoxamine. Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially: antipsychotics (e.g., olanzapine, clozapine), "water pills"/diuretics (e.g., furosemide), drugs that can cause bleeding/bruising (e.g., "blood thinners" such as heparin or warfarin, anti-platelet drugs including aspirin, NSAIDs such as ibuprofen), drugs removed from your body by certain liver enzymes (e.g., methadone, mexiletine, melatonin, tacrine, theophylline, certain benzodiazepines such as alprazolam/triazolam, certain anti-seizure drugs such as carbamazepine/phenytoin, certain beta blockers such as metoprolol/propranolol). Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (NSAIDs such as aspirin, ibuprofen, naproxen) that may increase your risk for bleeding if taken together with this drug. Low-dose aspirin should be continued if prescribed by your doctor for specific medical reasons such as heart attack or stroke prevention (usually at dosages of 81-325 milligrams per day). Consult your doctor or pharmacist for more details. Also tell your doctor if you take any other drugs that increase serotonin, such as amphetamines (e.g., dextroamphetamine), bromocriptine, buspirone, dextromethorphan, lithium, meperidine, propoxyphene, phentermine, tramadol, tryptophan, St. John's wort, drugs used to treat migraines (e.g., dihydroergotamine, "triptans" such as sumatriptan), street drugs such as MDMA/"ecstasy," certain antidepressants including other SSRIs (e.g., citalopram, paroxetine) and SNRIs (e.g., duloxetine, venlafaxine). Also report the use of drugs that might increase seizure risk when combined with fluvoxamine such as isoniazid (INH), tramadol, bupropion, or tricyclic antidepressants (e.g., amitriptyline, clomipramine), among others. Consult your doctor or pharmacist for details. This medication can increase the side effects of caffeine. Avoid drinking large amounts of beverages containing caffeine (coffee, tea, colas) or eating large amounts of chocolate. Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as: certain antihistamines (e.g., diphenhydramine), medicine for sleep or anxiety (e.g., lorazepam, zolpidem), muscle relaxants, narcotic pain relievers (e.g., codeine). Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain dextromethorphan, caffeine, or ingredients that cause drowsiness. Ask your pharmacist about using those products safely. Cigarette smoking decreases blood levels of this medication. Tell your doctor if you smoke or if you have recently stopped smoking.
