  • If you have any thoughts of harming yourself or ending your life, talk to a friend, your doctor or go to hospital straight away.
  • Fluvoxamine is used in children over 8 years to treat obsessive compulsive disorder, not depression.

About fluvoxamine

Type of medicineSelective serotonin reuptake inhibitor (SSRI) antidepressant
Used forDepression
Obsessive-compulsive disorder (OCD)
Also calledFluvoxamine maleate
Faverin®
Available asTablets

Fluvoxamine is an antidepressant. It is used to treat depression in adults and it can also be used to relieve the symptoms of obsessive-compulsive disorder in adults and children over the age of 8 years.

The exact cause of depression is not known, but a chemical imbalance in parts of our brain which control how we feel might be a factor. It is thought that low levels of a chemical called serotonin can lead to depression and other related conditions. Fluvoxamine works by helping to regulate serotonin levels in our body, easing the symptoms of depression and obsessive-compulsive disorder.

Before taking fluvoxamine

Before taking fluvoxamine make sure your doctor or pharmacist knows:

  • If you have heart, liver or kidney problems.
  • If you have epilepsy, diabetes or glaucoma.
  • If you are receiving electroconvulsive therapy (ECT).
  • If you have ever suffered from mania (an abnormally 'high' mood).
  • If you have a blood disorder or have had problems with bleeding.
  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have ever had an allergic reaction to this or to any other medicine.
  • If you are taking any other medicines, including those available to buy without a prescription, herbal or complementary medicines. This is particularly important if you have recently taken a type of antidepressant called a Monoamine Oxidase Inhibitor (MAOI).

How to take fluvoxamine

  • Before starting this treatment, read the manufacturer's printed information leaflet.
  • Take fluvoxamine exactly as your doctor has told you to. It is usually taken once a day in the evening, although you may be asked to take fluvoxamine two or three times a day.
  • Swallow fluvoxamine tablets with a drink of water. It is not important whether you take the tablets before or after food.
  • If you forget to take a dose and it is still within the same day, take it as soon as you remember. If you only remember through the night or during the next day, leave out the missed dose and take the next dose when it is due. Do not take two doses together to make up for a missed dose.

Getting the most from your treatment

  • It may take between two and four weeks for you to feel the benefits of fluvoxamine, but it is very important that you keep taking it even if it doesn't seem to make much difference at first.
  • Keep your regular appointments with your doctor so your progress can be checked.
  • If you feel your depression is getting worse, or if you have any distressing thoughts or feelings while you are taking fluvoxamine, then you should talk to your doctor as soon as possible.
  • Fluvoxamine may slow your reactions. Make sure your reactions are normal before driving, operating machinery or doing any other jobs which would be dangerous if you were not fully alert.
  • It is sensible to avoid drinking alcohol while you are being treated with fluvoxamine. Taking fluvoxamine and alcohol increases the chance that you may experience side-effects.
  • If you have diabetes you may need to check your blood glucose more frequently, as fluvoxamine may affect the levels of sugar in your blood. Your doctor will be able to advise you about this.
  • If you are being treated for depression, your doctor is likely to continue your treatment for at least 6 months even if you are feeling better.
  • Do not stop taking fluvoxamine without speaking with your doctor first. Your doctor will want to reduce your dose gradually, as stopping suddenly can cause problems.
  • If you buy any medicines, check with a pharmacist that they are safe to take with fluvoxamine.
