Fluoxetine Ratiopharm – Fluoxetine uses, dose and side effects


10 mg soluble tablets

What Fluoxetine Ratiopharm is and what it is used for

Fluoxetine Ratiopharm contains the active substance fluoxetine which belongs to a group of medicines called selective serotonin reuptake inhibitors ( SSRIs ).

Fluoxetine Ratiopharm is used to treat the following diseases:

In adults:

  • actually depression
  • obsessive-compulsive disorder
  • bulimia: Fluoxetine Ratiopharm is used in combination with psychotherapy to reduce binge eating and self-cleansing.

In 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 Ratiopharm should be given to a child or adolescent with moderate to severe depression only in combination with psychological treatment.

How Fluoxetine Ratiopharm works

Everyone has a substance called serotonin in the brain. People who are depressed, have obsessive-compulsive disorder or bulimia have lower levels of serotonin than others. It is not entirely clear how Fluoxetine Ratiopharm and other SSRIs work, but they can help by increasing the level of serotonin in the brain. It is important to treat these conditions for you to feel better. If left untreated, these conditions will not go away and may become more serious and difficult to treat.

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

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

What you need to know before you take Fluoxetine Ratiopharm

Do not take Fluoxetine Ratiopharm:

  • if you are allergic to fluoxetine or any of the other ingredients of this medicine (listed in section 6). Stop taking the tablets and contact your doctor immediately if you get a rash or other allergic reactions (such as itching, swollen face or lips, or difficulty breathing).
  • if you are taking other medicines called irreversible, non-selective monoamine oxidase inhibitors ( MAOIs ), as serious side effects and even death can occur (eg iproniazid used to treat depression). Treatment with Fluoxetine Ratiopharm should only be started if 2 weeks have elapsed after treatment with an irreversible non-selective MAOI.Do not take any irreversible, non-selective MAOI until at least 5 weeks after the end of treatment with Fluoxetine Ratiopharm. If Fluoxetine Ratiopharm has been used for a long time and/or in a high dose, your doctor may decide on a longer time interval.
  • if you are taking metoprolol (to treat heart failure ) as there is an increased risk of your heart rate becoming too slow.

Warnings and cautions

Talk to your doctor or pharmacist before taking Fluoxetine Ratiopharm if you:

  • have any heart disease.
  • have or previously had mania.
  • previously had problems with bleeding or if you are pregnant (see “Pregnancy, breast-feeding and fertility ).
  • use blood-thinning drugs (see “Other drugs and Fluoxetine Ratiopharm”).
  • have epilepsy or previously had seizures.
  • receive electrical therapy (electroconvulsive therapy).
  • receive treatment with tamoxifen (used to treat breast cancer) (see “Other medicines and Fluoxetine Ratiopharm”).
  • have diabetes (your doctor may change the dose of insulin or other medicines to treat diabetes ).
  • have liver problems (your doctor may need to change dose one).
  • have a low resting heart rate and/or know that you have a salt deficiency due to prolonged severe diarrhea and vomiting or use diuretics ( diuretics ).
  • Take diuretics ( diuretic tablets), especially if you are older.
  • have glaucoma (increased pressure in the eye).
  • have ongoing treatment with any other medicine (see “Other medicines and Fluoxetine Ratiopharm”).

Talk to your doctor if you experience any of the following during treatment:

  • Heart problems
  • Presence of bruising or unusual bleeding.
  • If you suddenly have a fever, muscle stiffness, or tremors and change mentally, for example, become confused, irritated, and extremely anxious. You may have had so-called serotonergic syndrome or malignant neuroleptic syndrome. It is rare for this syndrome to occur but if it does occur it can give rise to potentially life-threatening conditions. Contact your doctor immediately as Fluoxetine treatment may need to be stopped.
  • If you get a manic episode, contact your doctor immediately. Fluoxetine treatment may need to be stopped.
  • If you experience seizures (epileptic seizures) or experience an increase in seizures, contact your doctor immediately. Fluoxetine treatment may need to be stopped.
  • If you start to feel restless and can not sit still ( akathisia ). This can get worse if your Fluoxetine dose is increased.

Suicidal ideation and worsening depression or anxiety disorder

You who are depressed and/or suffer from worry/anxiety may 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 may be helpful to tell a relative or close friend that you are depressed and/or suffering from anxiety. 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.

Children and adolescents 8 to 18 years

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 Ratiopharm 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 for the treatment of other diseases.

Also, there are only limited data from this age group regarding the long-term safety of fluoxetine, such as effects on height growth, puberty development, mental, emotional, and behavioral development.

Despite this, Fluoxetine Ratiopharm can be prescribed by a doctor to you who are under 18 years of age 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 Ratiopharm, consult your doctor again. You should also tell your doctor if you notice any of the above symptoms or if they get worse.

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

Sexual dysfunction 

Drugs such as Fluoxetine Ratiopharm (so-called SSRIs ) can cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after discontinuation of treatment.

Other medicines and Fluoxetine Ratiopharm

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Do not take Fluoxetine ratiopharm with you

  • some irreversible, non-selective  MAO inhibitors, some of which are used to treat depression. Irreversible, non-selective MAOIs should not be used with Fluoxetine ratiopharm as serious side effects and even death (serotonergic syndrome) may occur (See section “Do not take fluoxetine ratiopharm”).
  • metoprolol, when used for heart failure; there is an increased risk that your heartbeat may become too slow.

Fluoxetine ratiopharm may affect the action of the following medicines ( interaction )

  • tamoxifen (used to treat breast cancer); Because Fluoxetine Ratiopharm may alter the blood levels of this medicine, which may lead to a reduction in the effect of tamoxifen, your doctor may need to consider another antidepressant treatment.
  • monoamine oxidase inhibitor  A  (MAO-A inhibitor ) including moclobemide, linezolid (an antibiotic ), and methylthionine chloride (also known as methylene blue which is used to treat high levels of methemoglobin in the blood); due to the risk of serious and even fatal reactions (called serotonergic syndrome). Treatment with fluoxetine may be started the day after treatment with reversible MAOIs is stopped, but your doctor may want to monitor you closely and use a lower dose of MAO-A inhibitor.
  • mequitazine (for allergy ); as there is an increased risk of changes in the electrical activity of the heart if you take this medicine with Fluoxetine ratiopharm.
  • phenytoin (used to treat epilepsy ). Because Fluoxetine Ratiopharm may affect the blood levels of this medicine, your doctor may need to use phenytoin more carefully and perform regular check-ups as Fluoxetine Ratiopharm is given at the same time.
  • lithium, selegiline, (traditional) herbal medicines containing  St. John’s wort, tramadol (painkillers), triptans  (for migraines ), and tryptophan; the risk of the mild serotonergic syndrome is greater as these drugs are co-administered with Fluoxetine Ratiopharm. Your doctor will perform more frequent check-ups.
  • drugs that can affect the heart rhythm, such as Class IA and III antiarrhythmics (drugs for irregular heart activity),  antipsychotics (eg phenothiazines, pimozide, haloperidol ), tricyclic antidepressants, certain antimicrobial drugs (eg sparfloxacin, moxifloxacin, moxifloxacin, IV ) pentamidine), treatment against malaria particularly halofantrine, some antihistamine s (astemizole, mizolastine); as the use of one or more of these medicines together with Fluoxetine Ratiopharm may increase the risk of changes in the electrical activity of the heart.
  • anticoagulants (such as warfarin ), NSAIDs (such as ibuprofen, diclofenac ), acetylsalicylic acid, and other drugs that can make the blood thinner (including clozapine, which is used to treat certain mental disorders). Fluoxetine ratiopharm may alter the effect of these medicines on the blood. If you are starting or stopping treatment with Fluoxetine ratiopharm while taking warfarin, your doctor will need to take some samples, adjust your dose and check you more often.  
  • cyproheptadine (for allergies ); as it may reduce the effect of Fluoxetine ratiopharm.
  • drugs that lower sodium levels in the blood (including drugs that increase urine output, desmopressin, carbamazepine, and oxcarbazepine); as they increase the risk of too low a sodium level in the blood when taken with Fluoxetine Ratiopharm.
  • antidepressants such as tricyclic antidepressants, other selective serotonin reuptake inhibitors ( SSRIs ) or bupropion, mefloquine or chloroquine (used to treat malaria ), tramadol (used to treat severe pain), or antipsychotics (such as phenothiazines or butyrophenones); as Fluoxetine Ratiopharm may increase the risk of seizures if taken at the same time as these medicines.
  • flecainide, propafenone, nebivolol or encainide, (used in heart disease), carbamazepine (used in epilepsy ), atomoxetine or tricyclic antidepressants (eg imipramine, desipramine, and amitriptyline ), or risperidone (for schizophrenia); Because Fluoxetine Ratiopharm may change the blood concentration of these medicines, your doctor may need to lower the dose of one of these medicines as they are being given at the same time as Fluoxetine Ratiopharm.

Fluoxetine ratiopharm with food, drink, and alcohol

You can take Fluoxetine ratiopharm between meals or with a meal.
You should avoid alcohol while taking fluoxetine.

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.


Studies have shown 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 ratiopharm.

When drugs such as fluoxetine 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 possible, this medicine should not be used during pregnancy unless the benefit outweighs the potential risk. Thus, you and your doctor may decide to gradually stop taking Fluoxetine ratiopharm if you are pregnant or planning to become pregnant. However, depending on your situation, your doctor may suggest that you should continue treatment with Fluoxetine ratiopharm.

Caution should be exercised when using during pregnancy, especially during the latter part of pregnancy or just before delivery as the following effects have been observed in newborns: irritability, tremors, muscle weakness, persistent crying, and difficulty in sucking or sleeping.

If you take Fluoxetine ratiopharm at the end of your pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should be informed that you are taking Fluoxetine ratiopharm so that they can advise you on this.


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 of fluoxetine.


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.

Driving and using machines

Psychotropic drugs such as Fluoxetine ratiopharm may impair judgment and coordination. Do not drive or use machines until you know how Fluoxetine ratiopharm affects you. You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened 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.
