Patient leaflet - Fluoxetine Neuraxpharm 10 mg tablets

1. What Fluoxetine tablets are and what they are used for What Fluoxetine tablets are

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:

  • Major depressive episodes
  • Obsessive-compulsive disorder
  • Bulimia nervosa: Fluoxetine is used alongside psychotherapy for the reduction of binge-eating and purging

Children and adolescents aged 8 years and

above:

  • Moderate to severe major depressive disorder, if the depression does not respond to psychological therapy after 4 - 6 sessions. Fluoxetine should be offered to a child or young person with moderate to severe major depressive disorder only in combination with psychological therapy.

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.

2. What you need to know before you take Fluoxetine tablets

Do not take Fluoxetine if you are:

  • allergic to fluoxetine or any of the other ingredients of this medicine (listed in section 6). If you develop a rash or other allergic reactions (like itching, swollen lips or face or shortness of breath), stop taking the tablets straight away and contact your doctor immediately.
  • taking other medicines known as irreversible, non-selective monoamine oxidase inhibitors (MAOIs), since serious or even fatal reactions can occur (e.g. iproniazid used to treat depression).

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.

  • taking metoprolol (to treat heart failure) since there is an increased risk of your heart beat becoming too slow.

Warnings and precautions

Talk to your doctor or pharmacist before taking

Fluoxetine if any of the following applies to you:

  • heart problems;
  • appearance of fever, muscle stiffness or tremor, changes in your mental state like confusion, irritability and extreme agitation; you may suffer from the so-called “serotonin syndrome” or “neuroleptic malignant syndrome”. Although this syndrome occurs rarely it may result in potentially life threatening conditions; contact your doctor immediately, since fluoxetine might need to be discontinued.
  • mania now or in the past; if you have a manic episode, contact your doctor immediately because fluoxetine might need to be discontinued;
  • history of bleeding disorders or appearance of bruises or unusual bleeding or if you are pregnant (see ‘Pregnancy);
  • ongoing treatment with medicines that thin the blood (see ‘Other medicines and Fluoxetine ´);
  • epilepsy or seizures. If you have a fit (seizures) or experience an increase in seizure frequency, contact your doctor immediately; fluoxetine might need to be discontinued;
  • ongoing ECT (electro-convulsive therapy);
  • ongoing treatment with tamoxifen (used to treat breast cancer) (see ‘Other medicines and Fluoxetine’);
  • starting to feel restless and cannot sit or stand still (akathisia). Increasing your dose of fluoxetine may make this worse;
  • diabetes (your doctor may need to adjust your dose of insulin or other antidiabetic treatment);
  • liver problems (your doctor may need to adjust your dosage);
  • low resting heart-rate and/or if you know that you may have salt depletion as a result of prolonged severe diarrhoea and vomiting (being sick) or usage of diuretics (water tablets);
  • ongoing treatment with diuretics (water tablets), especially if you are elderly;
  • glaucoma (increased pressure in the eye).
  • medicines like Fluoxetine (so called (SSRIs/ SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms have continued after stopping treatment.
  • The use of Buprenorphine together with Fluoxetine can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Fluoxetine capsules”). Thoughts of suicide and worsening of your

depression or anxiety disorder.

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 previously had thoughts about killing or harming yourself.
  • If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant.

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.

Other medicines and Fluoxetine

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:

  • Buprenorphine/opioids. These medicines may interact with fluoxetine and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, hallucinations, coma, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38ºC. Contact your doctor when experiencing such symptoms.

Do not take Fluoxetine with:

  • Certain irreversible, non-selective monoamine oxidase inhibitors (MAOIs), some used to treat depression. Irreversible, non-selective MAOIs must not be used with fluoxetine as serious or even fatal reactions (serotonin syndrome) can occur (see section “Do not take Fluoxetine ”). Treatment with Fluoxetine should only be started at least 2 weeks after discontinuation of an irreversible, non-selective MAOI (for instance tranylcypromine). 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 than 5 weeks may need to be considered by your doctor.
  • metoprolol when used for heart failure; there is an increased risk of your heart beat becoming too slow.

Fluoxetine may affect the way the following medicines work (interaction):

  • tamoxifen (used to treat breast cancer); because fluoxetine may change the blood levels of this drug, resulting in the possibility of a reduction in the effect of tamoxifen, your doctor may need to consider prescribing a different antidepressant treatment.
  • monoamine oxidase inhibitors A (MAOI-A) including moclobemide, linezolid (an antibiotic) and methylthioninium chloride (also called methylene blue used for the treatment of medicinal or chemical product induced methaemoglobinaemia): due to the risk of serious or even fatal reactions (called serotonin syndrome). Treatment with fluoxetine can be started the day after stopping treatment with reversible MAOIs but the doctor may wish to monitor you carefully and use a lower dose of the MAOI-A drug.
  • mequitazine (for allergies); because taking this drug with fluoxetine may increase the risk of changes in the electrical activity of the heart.
  • phenytoin (for epilepsy); because fluoxetine may influence the blood levels of this drug, your doctor may need to introduce phenytoin more carefully and carry out check-ups when given with Fluoxetine.
  • lithium, selegiline, St. John’s Wort, tramadol (a painkiller), triptans (for migraine) and tryptophan; there is an increased risk of mild serotonin syndrome when these drugs are taken with Fluoxetine. Your doctor will carry out more frequent check-ups.
  • medicines that may affect the heart’s rhythm, e.g. Class IA and III antiarrhythmics, antipsychotics (e.g. phenothiazine derivatives, pimozide, haloperidol), tricyclic antidepressants, certain antimicrobial agents (e.g. sparfloxacin, moxifloxacin, erythromycin IV, pentamidine), anti-malaria treatment particularly halofantrine or certain antihistamines (astemizole, mizolastine), because taking one or more of these drugs with fluoxetine may increase the risk of changes in the electrical activity of the heart.
  • Anti-coagulants (such as warfarin), NSAID (such as ibruprofen, diclofenac), aspirin and other medicines which can thin the blood (including clozapine, used to treat certain mental disorders). Fluoxetine may alter the effect of these medicines on the blood. If Fluoxetine treatment is started or stopped when you are taking warfarin, your doctor will need to perform certain tests, adjust your dose and check on you more frequently.
  • cyproheptadine (for allergies); because it may reduce the effect of Fluoxetine.
  • drugs that lower sodium levels in the blood (including, drug that causes increase in urination, desmopressin, carbamazepine and oxcarbazepine); because these drugs may increase the risk of sodium levels in the blood becoming too low when taken with Fluoxetine.
  • anti-depressants such as tricyclic anti-depressants, other selective serotonin reuptake inhibitors (SSRIs) or bupropion, mefloquine or chloroquine (used to treat malaria), tramadol (used to treat severe pain) or anti-psychotics such as phenothiazines or butyrophenones; because fluoxetine may increase the risk of seizures when taken with these medicines.
  • flecainide, propafenone, nebivolol or encainide (for heart problems), carbamazepine (for epilepsy), atomoxetine or tricyclic antidepressants (for example imipramine, desipramine and amitriptyline) or risperidone (for schizophrenia); because fluoxetine may possibly change the blood levels of these medicines, your doctor may need to lower their dose when administered with Fluoxetine. Fluoxetine with food, drink and alcohol

  • You can take Fluoxetine with or without food, whatever you prefer.
  • You should avoid alcohol while you are taking this medicine.

Pregnancy, breast-feeding and fertility

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 Package leaflet: Information for the patient

  1. 1.

    Draft: 11-February-2026

    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. Driving and using machines

    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.

    Fluoxetine contains sodium

    This medicine contains less than 1 mmol

    sodium (23 mg) per tablet, that is to say essentially sodium-free.

3. How to take Fluoxetine tablets

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.

Adults:

The recommended dose is:

  • Depression: The recommended dose is 2 tablets (20 mg) daily. Your doctor will review and adjust your dosage if necessary within 3 to 4 weeks of the start of treatment. If required, the dosage can be gradually increased up to a maximum of 6 tablets (60 mg) daily. The dose should be increased carefully to ensure that you receive the lowest effective dose. You may not feel better immediately when you first start taking your medicine for depression. This is usual because an improvement in depressive symptoms may not occur until after the first few weeks. Patients with depression should be treated for at least 6 months.
  • Bulimia nervosa: The recommended dose is 6 tablets (60 mg) daily.
  • Obsessive-compulsive disorder: The recommended dose is 2 tablets (20 mg) daily. Your doctor will review and adjust your dosage if necessary after 2 weeks of treatment. If required, the dosage can be gradually increased up to a maximum of 6 tablets (60 mg) daily. If no improvement is noted within 10 weeks, your doctor will reconsider your treatment.

Use in children and adolescents aged 8 to

18 years with depression:

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.

Elderly:

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.

Liver impairment:

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.

If you take more Fluoxetine than you should

  • If you take too many tablets, go to your nearest hospital emergency department (or casualty) or tell your doctor straight away.
  • Take the pack of Fluoxetine with you if you can. 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.

If you forget to take Fluoxetine

  • If you miss a dose, do not worry. Take your next dose the next day at the usual time. Do not take a double dose to make up for a forgotten dose.
  • Taking your medicine at the same time each day may help you to remember to take it regularly.

If you stop taking Fluoxetine

  • Do not stop taking Fluoxetine tablets without asking your doctor first, even when you start to feel better. It is important that you keep taking your medicine.
  • Make sure you do not run out of tablets. You may notice the following effects

(withdrawal effects) when you stop taking Fluoxetine tablets: dizziness; tingling feelings like pins and needles; sleep disturbances (vivid dreams, nightmares, inability to sleep); feeling restless or agitated; unusual tiredness or weakness; feeling anxious; nausea/vomiting (feeling sick or being sick); tremor (shakiness); headaches.

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.

If you have any further questions on the use of

this medicine, ask your doctor or pharmacist.
