Try to take fluvoxamine at the same time each evening.
It may take up to four weeks after starting this treatment before you feel the full benefit. Do not stop taking it, feeling it is not helping.
Tell your doctor if you feel that you are getting worse, or if you experience any troublesome side-effects.
|Type of medicine||Selective serotonin reuptake inhibitor (SSRI) antidepressant|
|Used for||Depression in adults, and obsessive-compulsive disorder (OCD) in adults and children over 8 years of age|
Depression and anxiety disorders like obsessive-compulsive disorder (OCD) can develop for no apparent reason, or may be triggered by a life event such as a relationship problem, bereavement, or illness.
Brain cells called neurons, release a number of chemicals which go on to stimulate other neurons. This leads to electrical impulses which result in many functions controlled by the brain. Serotonin is one such chemical in the brain. Once released, it stimulates other neurons and is then taken back up into the neuron cells and recycled. SSRI antidepressants like fluvoxamine increase the amount of circulating serotonin available in your brain. This may help the symptoms of depression and OCD in some people. Fluvoxamine is mainly prescribed for adults. It may be prescribed for older children to treat OCD, but not depression.
Before taking fluvoxamine
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking fluvoxamine it is important that your doctor or pharmacist knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have heart, liver or kidney problems.
- If you have epilepsy.
- If you have diabetes.
- If you have glaucoma (increased pressure in your eye).
- If you have ever had a bleeding disorder.
- If you have ever had abnormally 'high' moods, called mania.
- If you are being treated with electroconvulsive therapy (ECT).
- If you have ever had an allergic reaction to a medicine.
- If you have taken an antidepressant known as a monoamine-oxidase inhibitor (MAOI) within the previous two weeks.
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
How to take fluvoxamine
- Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about fluvoxamine and a full list of side-effects which you may experience from taking it.
- Take fluvoxamine exactly as your doctor has told you to. It is usually taken once a day in the evening. After a few weeks, your doctor may decide to increase your dose gradually if this is needed. Increasing it slowly allows your doctor to make sure that you have the dose that helps your condition, but avoids any unwanted symptoms.
- Swallow the tablets with a drink of water. You can take fluvoxamine 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
- You may feel that fluvoxamine is not working for you straightaway. It can take a week or two after starting this treatment before the effect begins to build up, and 4-6 weeks before you feel the full benefit. Do not stop taking it after a week or two, feeling it is not helping.
- Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
- If you drink alcohol, ask your doctor for advice. Your doctor is likely to recommend that you do not drink alcohol while you are on fluvoxamine, as it increases the risk of side-effects, such as feeling sleepy.
- 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 buy any medicines, check with a pharmacist that they are safe to take with fluvoxamine. This is because several medicines which are available from general retail outlets can interfere with this treatment. In particular, do not take the herbal remedy St John's wort, and ask for advice before buying any anti-inflammatory painkillers.
- There are several types of antidepressants and they differ in their possible side-effects. If you find that fluvoxamine does not suit you then let your doctor know, as another may be found that will.
- While you are taking fluvoxamine, you may have thoughts about harming yourself or ending your life. These thoughts may also be associated with your condition. It is very important that you tell your doctor about this if it happens.
- If you are taking fluvoxamine for depression, you should expect that your treatment will last for several months after your symptoms have eased. This is normal and helps to prevent your symptoms from recurring.
- Do not stop taking fluvoxamine unless your doctor tells you to do so. Stopping treatment suddenly can cause problems and your doctor will probably want you to reduce your dose over a couple of weeks when this becomes necessary.
Can fluvoxamine cause problems?
Along with their useful effects, all medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.
|Common fluvoxamine side-effects - these affect less than 1 in 10 people who take this medicine||What can I do if I experience this?|
|Feeling or being sick, indigestion, abdominal discomfort, diarrhoea||Stick to simple meals - avoid rich or spicy food. Drink plenty of liquid to replace any lost fluids|
|Headache||Ask your pharmacist to recommend a suitable painkiller|
|Dry mouth||Try chewing sugar-free gum, or sucking sugar-free sweets|
|Feeling dizzy, tired or sleepy||If this happens, do not drive or use tools or machines|
|Feeling restless, weak, shaky, or anxious||This usually settles within a few days. If it becomes troublesome or severe, speak with your doctor|
|Constipation||Try to eat a well-balanced diet containing plenty of fibre, and drink several glasses of water each day|
|Changes in appetite and weight, sweating, palpitations, and sleeping problems||If any of these become troublesome, speak with your doctor|
Important: a few people taking fluvoxamine have developed an allergic-type reaction. Although this is rare, you should contact your doctor straightaway if you develop any swelling around your face, any difficulties breathing, or a severe rash.
If you experience any other symptoms which you think may be due to this medicine, discuss them with your doctor or pharmacist.
