Fluoxetine tablets contain the active substance fluoxetine which is one of a group of medicines called selective serotonin re-uptake inhibitors (SSRI) antidepressants.
This medicine is used to treat the following conditions:
Adults:
Children and adolescents aged 8 years and above:
How Fluoxetine works
Everyone has a substance called serotonin in their brain. People who are depressed or have obsessive-compulsive disorder or bulimia nervosa have lower levels of serotonin than others. It is not fully understood how Fluoxetine and other SSRIs work but they may help by increasing the level of serotonin in the brain.
Treating these conditions is important to help you get better. If it’s not treated, your condition may not go away and may become more serious and more difficult to treat.
You may need to be treated for a few weeks or months to ensure that you are free from symptoms.
Treatment with Fluoxetine should only be started at least 2 weeks after discontinuation of an irreversible, non-selective MAOI.
Do not take any irreversible, non-selective MAOIs for at least 5 weeks after you stop taking Fluoxetine. If Fluoxetine has been prescribed for a long period and/or at a high dose, a longer interval needs to be considered by your doctor.
Talk to your doctor or pharmacist before taking Fluoxetine if any of the following applies to you:
If you are depressed and/or have anxiety disorders you can sometimes have thoughts of harming or killing yourself. These may be increased when first starting antidepressants, since these medicines all take time to work, usually about two weeks but sometimes longer.
You may be more likely to think like this:
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.
You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behaviour.
Children and adolescents aged 8 to 18 years:
Patients under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, oppositional behaviour and anger) when they take this class of medicines. Fluoxetine should only be used in children and adolescents aged 8 to 18 years for the treatment of moderate to severe major depressive episodes (in combination with psychological therapy) and it should not be used to treat other conditions.
Additionally, only limited information concerning the long-term safety of fluoxetine on growth, puberty, mental, emotional and behavioural development in this age group is available. Despite this, and if you are a patient under 18, your doctor may prescribe fuoxetine for moderate to severe major depressive episodes, in combination with psychological therapy, because he/she decides that this is in your best interests. If your doctor has prescribed fluoxetine for a patient under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen when patients under 18 are taking fluoxetine.
Fluoxetine should not be used in the treatment of children under the age of 8 years.
Tell your doctor or pharmacist if you are taking/using, have recently taken/used or might take/use any other medicines.
Some medicines may increase the side effects of Fluoxetine and may sometimes cause very serious reactions. Do not take any other medicines whilst taking Fluoxetine without first talking to your doctor, especially:
Do not take Fluoxetine with:
Fluoxetine may affect the way the following medicines work (interaction):
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Talk to your doctor as soon as possible if you're pregnant, if you might be pregnant, or if you're planning to become pregnant.
In babies whose mothers took fluoxetine during the first few months of pregnancy, there have been some studies describing an increased risk of birth defects affecting the heart. In the general population, about 1 in 100 babies are born with a heart defect. This increased to about 2 in 100 babies in mothers who took fluoxetine.
When taken during pregnancy, particularly in the last 3 months of pregnancy, medicines like fluoxetine may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your baby you should contact your midwife and/or doctor immediately.
If you take fluoxetine near the end of your pregnancy there may be an increased risk of heavy vaginal bleeding shortly after birth, especially if you have a history of bleeding disorders. Your doctor or midwife should be aware that you are taking Fluoxetine so they can advise you.
It is preferable not to use this treatment during pregnancy unless the potential benefit outweighs the potential risk. Thus, you and your doctor may decide to gradually stop taking Fluoxetine while you are pregnant or before being pregnant. However, depending on your circumstances, your doctor may suggest that it is better for you to keep taking Fluoxetine.
Caution should be exercised when used during pregnancy, especially during late pregnancy or just before giving birth since the following effects have been reported in new born children: irritability, tremor, muscle weakness, persistent crying, and difficulty in sucking or in sleeping.
Breast-feeding
Fluoxetine is excreted in breast milk and can cause side effects in babies. You should only breast-feed if it is clearly necessary. If breast-feeding is continued, your doctor may prescribe a lower dose of fluoxetine.
Fertility
Fluoxetine has been shown to reduce the quality of sperm in animal studies. Theoretically, this could affect fertility, but impact on human fertility has not been observed as yet.
Psychotropic drugs such as fluoxetine may affect your judgment or co-ordination. Do not drive or use machinery until you know how Fluoxetine affects you.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially sodium-free.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. Do not take more tablets than your doctor tells you.
Swallow the tablets with a drink of water. Do not chew the tablet.
The recommended dose is:
Treatment should be started and be supervised by a specialist. The starting dose is 10 mg daily. After 1 to 2 weeks, your doctor may increase the daily dose to 20 mg. The dose should be increased carefully to ensure that you receive the lowest effective dose. Lower weight children may need lower doses. If there is a satisfactory response to treatment, your doctor will review the need for continuing treatment beyond 6 months. If you have not improved within 9 weeks, your doctor will reassess your treatment.
Your doctor will increase the dose with more caution and the daily dose should generally not exceed 4 tablets (40 mg). The maximum dose is 6 tablets (60 mg) daily.
If you have a liver problem or are using other medication that might affect fluoxetine, your doctor may decide to prescribe a lower dose or tell you to take Fluoxetine tablets every other day.
Symptoms of overdose include: nausea, vomiting, seizures, heart problems (like irregular heart beat and cardiac arrest), lung problems and change in mental condition ranging from agitation to coma.

Most people find that any symptoms on stopping fluoxetine are mild and disappear within a few weeks. If you experience symptoms when you stop treatment, contact your doctor.
When stopping Fluoxetine tablets, your doctor will help you to reduce your dose slowly over one or two weeks - this should help reduce the chance of withdrawal effects.
