Fluoxetine Orifarm – Fluoxetine uses, dose and side effects


20 mg dispersible tablet

What Fluoxetine Orifarm is and what it is used for

Fluoxetine Orifarm contains the active substance fluoxetine, which is part of a group of antidepressant medicines called selective serotonin reuptake inhibitors ( SSRIs ).

Fluoxetine Orifarm is used to treat:

Adults :

  • depression
  • obsessions and compulsions
  • bulimia (hunger); Fluoxetine Orifarm is used in combination with psychotherapy to reduce binge eating and self-cleansing.

Children and adolescents from 8 years of age:

  • Moderate to severe major depression, if depression does not improve after 4-6psychological treatment sessions. Fluoxetine Orifarm should be given to a child or adolescent with moderate to severe depression only in combination with psychological treatment.

How Fluoxetine Orifarm 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 Orifarm 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 Orifarm 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.

What you need to know before you use Fluoxetine Orifarm

Do not use Fluoxetine Orifarm

  • if you are allergic to fluoxetine or any of the other ingredients of this medicine (listed in section 6).
  • if you are taking or have recently taken medicines called irreversible non-selective monoamine oxidase inhibitors (also known as MAOIs ), serious side effects and even death can occur (eg iproniazid used to treat depression).
  • if you are taking metoprolol (to treat heart failure ), as there is an increased risk that your heartbeat will be too slow.

Treatment with Fluoxetine Orifarm should be started only 2 weeks after the end of 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 Orifarm. If Fluoxetine Orifarm has been used for a long time and/or in a high dose, your doctor may decide on a longer time interval.

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before using Fluoxetine Orifarm

  • if you have any heart disease.
  • if you suddenly have a fever, muscle stiffness, or tremor and change mentally, e.g. becomes confused, irritated, and extremely anxious. You may have had 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. Therefore, contact your doctor immediately. Fluoxetine treatment may need to be stopped.
  • if you have or have previously had mania. If you get a manic episode, contact your doctor immediately. Fluoxetine treatment may need to be stopped.
  • if you have a history of bleeding disorders, bruising, or unusual bleeding or if you are pregnant (see “Pregnancy, breast-feeding and fertility ”). 
  • if you are taking blood-thinning medicines (see “Other medicines and Fluoxetine Orifarm”).
  • if you have epilepsy or a history of seizures. If you get cramps or experience that the number of seizures increases in number, contact your doctor immediately. Fluoxetine treatment may need to be stopped.
  • if you are receiving electrical therapy (electroconvulsive therapy).
  • if you are being treated with tamoxifen (used to treat breast cancer) (see “Other medicines and Fluoxetine Orifarm”).
  • if you start to feel restless and can not sit still ( akathisia ). This may get worse if your fluoxetine dose is increased.
  • if you have diabetes. Your doctor may change the dose of insulin or other medicines for diabetes.
  • if you get a rash or other allergic reactions (such as itching, swollen face or lips, or difficulty breathing).
  • if you have liver problems.
  • if you have glaucoma (increased pressure in the eye).

Medicines such as Fluoxetine Orifarm ( SSRI / SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after discontinuation of treatment.

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

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 taking 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 Orifarm 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, such as effects on height growth, puberty development, mental, emotional, and behavioral development. Despite this, Fluoxetine Orifarm can be prescribed by a doctor to you who are under 18 years of age for moderate to severe real 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 Orifarm, consult your doctor again. You should also tell your doctor if you notice any of the above symptoms or if they get worse.

Fluoxetine Orifarm should not be used in the treatment of children under 8 years of age.

Withdrawal symptoms if you stop taking Fluoxetine Orifarm

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

Other medicines and Fluoxetine Orifarm

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

Do not take Fluoxetine Orifarm with:

  • irreversible non-selective MAOIs as severe side effects and even death (serotonergic syndrome) can occur. An example of such an MAO inhibitor is iproniazid which is used to treat depression. Treatment with Fluoxetine Orifarm should be started only 2 weeks after the end of 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 Orifarm. See also section “Do not use Fluoxetine Orifarm ”.
  • Metoprolol for heart failure should not be used with Fluoxetine Orifam as serious side effects may occur.

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

  • Tamoxifen (used to treat breast cancer). Because Fluoxetine Orifarm may alter the blood levels of this medicine, and a reduction in the effect of tamoxifen cannot be ruled out, your doctor may need to consider another antidepressant treatment.
  • MAO-A inhibitors such as 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).
  • Mequitazine (for allergies ); as there is an increased risk of changes in the electrical activity of the heart if you take this medicine with Fluoxetine Orifarm.
  • Phenytoin (for epilepsy ); Because Fluoxetine Orifarm may affect the blood levels of this medicine, your doctor may need to insert phenytoin more carefully and perform regular check-ups as Fluoxetine Orifarm is given at the same time.
  • Lithium (used in mono depressive disease), selegiline, tramadol (painkiller), triptans (drug group for migraines ), tryptophan (used in depression), selegiline (used in Parkinson’s disease ), St. John’s wort ((traditional) herbal medicine). There is an increased risk of the mild serotonergic syndrome as these medicines are given at the same time as Fluoxetine Orifarm. Your doctor will perform more frequent check-ups.
  • Drugs that can affect the heart rhythm, such as Class 1A and III antiarrhythmics (medicines for irregular heart activity), antipsychotics (eg phenothiazines, pimozide, haloperidol ), tricyclic antidepressants (medicines for depression), certain antimicrobial medicines (eg sparfloxacin moxifloxacin, erythromycin given intravenously, pentamidine), treatment against malaria particularly halofantrine or some antihistamine s (astemizole, mizolastine); because the use of one or more of these medicines together with Fluoxetine Orifarm 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 Orifarm may alter the effect of these medicines on the blood. If you are starting or stopping treatment with Fluoxetine Orifarm while taking warfarin, your doctor will need to take some samples, adjust your dose and check you more often.
  • Cyproheptadine (for allergies ); may reduce the effect of fluoxetine.
  • Drugs that lower the level of sodium in the blood (including drugs that increase the excretion of urine, desmopressin, carbamazepine, and oxcarbazepine); increase the risk of too low a sodium level in the blood when taken with Fluoxetine Orifarm.
  • 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 butyrophenones and phenothiazines); as Fluoxetine Orifarm may increase the risk of seizures if taken at the same time as these medicines.
  • Flecainide, propafenone, and nebivolol (used to treat heart disease), atomoxetine (used for ADHD ), carbamazepine (used for epilepsy ), tricyclic antidepressants (eg imipramine, desipramine, and amitriptyline), or risperidone (for schizophrenia); as Fluoxetine Orifarm may alter the blood levels of these medicines and your doctor may need to lower the dose of one of these medicines as they are being given at the same time as Fluoxetine Orifarm.

Fluoxetine Orifarm with food, drink, and alcohol

The tablets can be taken with or without food.

You should avoid using alcohol during treatment with this medicine.

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.


Tell your doctor as soon as possible that you are pregnant, think you may be pregnant, or are planning to become pregnant.

Reports of increased risk of heart defects in infants have been reported in mothers who used Fluoxetine Orifarm 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 approximately 2 in 100 when mothers were treated with Fluoxetine Orifarm.

When medicines such as Fluoxetine Orifarm 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 Orifarm if you are pregnant or planning to become pregnant. However, depending on the circumstances, your doctor may suggest that you should continue treatment with Fluoxetine Orifarm.

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, difficulty in sucking, and sleeping.

If you take Fluoxetine Orifarm 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 Orifarm 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.


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

This medicine may impair your judgment and coordination. Do not drive or use machines until you know how Fluoxetine Orifarm affects you.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased vigilance. 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.

Use in children and adolescents aged 8 to 18 years with depression:

Treatment should be initiated and supervised by a specialist. The starting dose is 10 mg per day. After one to two weeks, your doctor may increase the dose to one to 20 mg per day. Dose one should be increased carefully to ensure that you receive the lowest effective dose. Children with low body weight may need a lower dose. If the treatment gives good results, your doctor should assess the need for continued treatment after 6 months. If you have not improved within 9 weeks, the treatment should be reconsidered.
