How it works
Fluvoxamine is in a class of medication called selective serotonin reuptake inhibitors (SSRIs). It is used to treat depression, anxiety, obsessive-compulsive disorder, social anxiety disorder, and other conditions. Fluvoxamine works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance.
Fluvoxamine is a non-controlled medication, which means that it is not classified as having euphoric or addictive properties. There are no cravings, no hazardous behaviors, and no examples of prolonged addictive behavior associated with it.
Fluvoxamine may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you. Remember that alcohol can add to the drowsiness caused by this medication. You should not drink alcohol while taking fluvoxamine.
Tell your doctor if you use tobacco products. Cigarette smoking may decrease the effectiveness of this medication.
How it should be used
It may take 2 to 4 weeks or longer before you feel the full benefit of fluvoxamine. Continue to take fluvoxamine even if you feel well.
Do not stop taking fluvoxamine without talking to your doctor. If you suddenly stop taking fluvoxamine, you may experience withdrawal symptoms such as irritability; agitation; dizziness; extreme worry; uneasiness; confusion; headache; tiredness; mood changes; difficulty falling asleep or staying asleep; or pain, burning, numbness, tingling or ‘electric shock’ sensations in the hands or feet. Your doctor will probably decrease your dose gradually.
What to do if you forget a dose
Take the missed dose as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Fluvoxamine may cause side effects. However, they tend to go away after an adaptation period. Tell your doctor if any of these symptoms are severe or do not go away:
- difficulty concentrating, memory problems, or confusion

- decreased appetite
- weight loss
- changes in sex drive or ability
