Fluoxetine Sandoz – Fluoxetine uses, dose and side effects


20 mg dispersible tablets

What Fluoxetine Sandoz is and what it is used for

Fluoxetine Sandoz is an antidepressant drug that affects the central nervous system. Fluoxetine Sandoz contains the active substance fluoxetine.

Fluoxetine Sandoz is used for:


  • Depression.
  • Obsessions and compulsions.
  • Bulimia (binge eating).

Children and adolescents from 8 years of age:

  • Moderate to severe actual depression, if the depression has not improved after 4-6 psychological treatment sessions. Fluoxetine Sandoz should be given to children or adolescents with moderate to severe depression only in combination with psychological treatment.

How Fluoxetine Sandoz works

All people have a substance called serotonin in the brain. People who have depression or obsessive-compulsive disorder or bulimia have lower serotonin levels than others. It is not completely known how Fluoxetine Sandoz and other SSRIs work, but they can help by raising serotonin levels in the brain.

It is important to treat these conditions for you to feel better. If the condition is not treated, it may not go away and may become more serious and difficult to treat.

You may need to receive treatment for a few weeks or months to ensure that you are symptom-free.

Please note that your doctor may have prescribed this medicine for a different purpose and/or with a different dosage than what is stated in the package leaflet. Always follow your doctor’s prescription and the instructions on the label on the package.

Fluoxetine contained in Fluoxetine Sandoz may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

If you start to feel worse and have thoughts of harming yourself

You who are depressed can sometimes have thoughts of harming yourself or committing suicide. These symptoms may worsen when you start using antidepressants, as it takes time for this type of medicine to take effect, usually about 2 weeks, sometimes longer.

These thoughts may be common:

  • if you have previously had thoughts of harming yourself or committing suicide
  • if you are younger than 25 years. Studies have shown that young adults (younger than 25 years) with mental illness who are treated with antidepressant drugs have an increased risk of suicidal thoughts and thoughts of harming themselves.

Contact a doctor as soon as possible or see the nearest hospital if you have thoughts of injuring yourself or committing suicide.

It can be helpful to tell a relative or close friend that you are depressed. Feel free to ask them to read this leaflet. You can also ask them to tell you if they think you are feeling worse or if they think your behavior is changing.

Restlessness such as difficulty sitting or standing still, allergic reactions, or a combination of severe symptoms known as the serotonergic syndrome may occur during treatment with Fluoxetine Sandoz, see section 4.

Weight loss may occur during treatment with Fluoxetine Sandoz.

Children and young people

The risk of side effects such as suicide attempts, suicidal thoughts, and hostility (mainly aggression, defiance, and anger) is greater in patients under 18 years of age when taking drugs of this type. Fluoxetine Sandoz should only be used in children and adolescents aged 8 to 18 years for the treatment of moderate to severe major depression (in combination with psychological treatment) and should not be used in other indications. Also, there are only limited data in this age group regarding the long-term safety of Fluoxetine Sandoz, such as effects on height growth, puberty development, mental, emotional, and behavioral development. Despite this, Fluoxetine Sandoz is prescribed by a doctor to patients under the age of 18 for moderate to severe major depression in combination with psychological treatment as the doctor considers this to be in your best interest. If you are under 18 years of age and want to discuss why you received Fluoxetine Sandoz, you should consult your doctor again. You should also tell your doctor if you notice any of the above symptoms or if they get worse.

Fluoxetine Sandoz should not be used to treat children under 8 years of age.

Withdrawal symptoms if you stop taking Fluoxetine Sandoz

When you stop taking Fluoxetine Sandoz, especially if it happens abruptly, you may experience withdrawal symptoms (see “How to use Fluoxetine Sandoz”)

Other medicines and Fluoxetine Sandoz

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Some other medicines may affect or be affected by Fluoxetine Sandoz. These drugs are:

  • metoprolol used to treat heart failure, and irreversible non-selective MAOIs (eg iproniazid) must not be taken concomitantly with Fluoxetine Sandoz (see above under “Do not use Fluoxetine Sandoz”). If your doctor changes your medicine from a so-called irreversible non-selective MAOI (eg iproniazid) to Fluoxetine Sandoz, there should be at least 2 weeks between treatments. If you stop taking Fluoxetine Sandoz and the medication changes to an irreversible non-selective MAOI, it should be at least 5 weeks before you start taking the MAOI.
  • warfarin, anti-inflammatory drugs ( NSAIDs ), or other blood-thinning drugs (eg clozapine used for certain mental disorders, or acetylsalicylic acid ). Concomitant use of Fluoxetine Sandoz with such drugs increases the risk of bleeding. If treatment with Fluoxetine Sandoz is started or stopped while you are taking warfarin, your doctor will need to take some samples.
  • Lithium or tryptophan is used to treat depressed mood. There is an increased risk of serotonergic syndrome when these medicines are taken with fluoxetine. Your doctor will perform more frequent check-ups.
  • phenytoin is used to treat epilepsy. Fluoxetine may affect the concentration of this medicine in the blood and your doctor may need to insert phenytoin more carefully and perform checks while Fluoxetine Sandoz is being given at the same time.
  • tramadol is used to treat pain or triptans is used to treat migraines. There is an increased risk of the serotonergic syndrome. Triptans can also lead to narrowing of the heart’s blood vessels and high blood pressure when used concomitantly.
  • Antiarrhythmics of Class 1A or class III or other drugs which can affect heart rhythm; antipsychotics used to treat schizophrenia (eg phenothiazines, pimozide, haloperidol ); tricyclic antidepressants used to treat depression; certain antimicrobial drugs used to treat infections (eg sparfloxacin, moxifloxacin, erythromycin IV, pentamidine); halofantrine for malaria; astemizole, mizolastine, and mequitazine used to treat allergy s
  • diuretics, desmopressin, carbamazepine, oxcarbazepine and other medicines that can cause low levels of sodium in the blood.
  • tricyclic antidepressants, other selective serotonin reuptake inhibitors, phenothiazines, butyrophenones, Floxin, chloroquine, bupropion, tramadol, and other drugs that may lower the seizure threshold.
  • St. John’s wort (Hypericum perforatum, a (traditional) herbal medicine used to treat depression), MAO-A inhibitors (eg linezolid or methylthionine chloride [methylene blue]), selegiline, and other serotonergic medicines. Concomitant treatment with Fluoxetine Sandoz may lead to serious side effects (serotonergic syndrome).
  • flecainide, propafenone, or nebivolol used to treat heart problems; carbamazepine used to treat epilepsy; tricyclic antidepressants (eg imipramine, desipramine, and amitriptyline); atomoxetine used to treat ADHD; risperidone used to treat psychotic illnesses. If they are taken with Fluoxetine Sandoz, the blood levels of these medicines may change and your doctor may need to reduce the dose of one of these medicines.
  • tamoxifen is used to treat breast cancer. Fluoxetine Sandoz may alter the concentration of this drug in the blood and a reduction in the effect of tamoxifen can not be ruled out. Your doctor may consider choosing another treatment for depression.
  • cyproheptadine (used to treat allergies ) may reduce the antidepressant effect of fluoxetine.

Fluoxetine Sandoz with food, drink, and alcohol

The tablets can be taken with or without food.

The combination of Fluoxetine Sandoz and alcohol is not recommended.

Pregnancy, breastfeeding, 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.

Fluoxetine Sandoz should not be used during pregnancy and breast-feeding unless your doctor has decided that the risk of not using the medicine is greater than using it.

Taking Fluoxetine Sandoz during both pregnancy and lactation may affect the fetus / newborn baby.


There have been reports that there is an increased risk of heart defects in infants whose mothers used fluoxetine during the first months of pregnancy. In the population, approximately 1 in 100 babies is normally born with heart defects. This malformation increased in frequency to about 2 in 100 when mothers were treated with fluoxetine. You and your doctor may decide to gradually stop treatment if you are pregnant. Depending on the circumstances, however, your doctor may suggest that you should continue using Fluoxetine Sandoz.

Tell your midwife or doctor that you are using Fluoxetine Sandoz. When drugs such as Fluoxetine Sandoz are used during pregnancy, especially during the last three months, they may increase the risk of a serious condition called persistent pulmonary hypertension in the newborn (PPHN). This condition causes the baby to breathe faster and look blue. The symptoms usually appear within 24 hours of the baby being born. If this affects your baby, contact a midwife or doctor immediately.

If you are taking Fluoxetine Sandoz, especially during the latter part of your pregnancy or just before birth, your baby may have some symptoms at birth. These symptoms are irritability, tremors, muscle weakness, persistent crying, difficulty sucking and sleeping. These symptoms may indicate so-called serotonergic effects or withdrawal symptoms. If your baby has any of these symptoms at birth, contact your midwife or doctor who can advise you.


Fluoxetine passes into breast milk and may cause side effects in breast-fed infants. You should only breast-feed if necessary. If you continue to breast-feed, your doctor may prescribe a lower dose.


In animal studies, fluoxetine has been shown to reduce sperm quality. In theory, this could affect fertility, but no such reducing effect of fluoxetine on fertility has yet been demonstrated in humans.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines

Fluoxetine Sandoz may impair judgment, thinking ability, and motor skills. This should be observed in situations where increased attention is necessary, e.g. when driving or when using dangerous machinery.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
