6.Contents of the pack and other information

The active ingredient of Dumirox is fluvoxamine; it belongs to the group of medications known as selective serotonin reuptake inhibitors (SSRIs). It is an antidepressant and is used to treat depression (major depressive disorder).

Dumirox may also be used to treat individuals who suffer from obsessive-compulsive disorder (OCD)

Do not take Dumirox:

- if you are allergic (hypersensitive) to fluvoxamine or any of the other components of Dumirox (see section 6 “Additional information”)

- if you are being treated with medications called monoamine oxidase inhibitors (MAOIs) sometimes prescribed to treat depression or anxiety, including linezolid (an antibiotic that is also an MAOI).

The treatment with fluvoxamine should start at least 2 weeks after stopping an irreversible MAOI. However, treatment with fluvoxamine after stopping certain reversible MAOIs can be initiated the next day. In exceptional cases, linezolid (an antibiotic MAOI) can be used with fluvoxamine if your doctor closely monitors you.

Your doctor will advise you how to take Dumirox once you have stopped taking MAOIs

- if you are taking tizanidine, a medication often used as a muscle relaxant

- if you are breastfeeding

- if you are taking pimozide, a neuroleptic medication used in the treatment of schizophrenia and other psychiatric disorders

If any of the above circumstances apply to you, do not take Dumirox and consult your doctor

Warnings and precautions

Consult your doctor or pharmacist before taking the medication:

- if you have had a recent heart attack

- if you are pregnant, or think you may be pregnant

- if you have epilepsy

- if you have a history of bleeding problems or if you regularly take medications that increase the risk of bleeding, such as analgesics, or if you are pregnant (see “Pregnancy” 2)

- if you have diabetes

- if you are undergoing electroconvulsive therapy (ECT)

- if you have a history of having had mania (feeling of euphoria or overexcitement)

- if you have liver or kidney insufficiency

- if you have high eye pressure (glaucoma)

- if you are under 18 years old (see also section 3 “How to take Dumirox”)

- if you are taking medications that contain opioids such as buprenorphine or buprenorphine/naloxone, as these products taken in combination with Dumirox may cause serotonin syndrome, a potentially fatal condition (for symptoms, see section 4, "Possible side effects") and "Other medications and Dumirox".

If any of the above circumstances apply to you, your doctor will advise you whether it is safe for you to consult your doctor if they recommend starting Dumirox treatment.

In some cases, agitation ideas, cannot sit or stay still (akathisia) may occur in the first weeks of treatment with Dumirox, until the antidepressant effect is produced.

Inform your doctor immediately if you have these symptoms. Adjusting the dose may be helpful.

Severe skin reactions have been reported when using Dumirox.Stop takingDumirox and contact your doctor immediately if you develop a rash or lesions on the mucous membranes. Severe rashes may include skin rash, which begins on the extremities, usually on both sides of the body and evolving into concentric circles that resemble erythema (erythema multiforme), generalized rash with blisters and skin peeling, which occurs particularly around the mouth, nose, eyes, and genitals (Stevens-Johnson syndrome), extensive skin peeling (more than 30% of the body surface - toxic epidermal necrolysis).

Medications like Dumirox (called ISRS) may cause sexual dysfunction symptoms (see section 4). In some cases, these symptoms have continued after stopping treatment.

Ideas of suicide and worsening of your depression or anxiety disorder

If you are depressed and/or have an anxiety disorder, you may have ideas of self-harm or suicide. This may increase when starting antidepressant treatment for the first time, as these medications take time to take effect, usually two weeks, but sometimes longer.

You are likely to think this way if:

- you have previously had ideas of self-harm or suicide.

- you are a young adult. Information from clinical trials has shown an increase in the risk of suicidal behavior in adults under 25 years with psychiatric disorders who were treated with an antidepressant.

If you have ideas of self-harm or suicide,inform your doctor immediately or go directly to a hospital.

It may be very helpful to tell a family member or friendthat you are depressed or have an anxiety disorder, and ask them to read the leaflet. You can ask them for their opinion on whether your depression or anxiety is getting worse, or if they are concerned about the changes in your behavior.

Inform your doctor immediatelyif you have ideas or experiences that cause you distress.

Use in children and adolescents under 18 years old

Children and adolescents under 18 years old should not take this medication, unless they are being treated for obsessive-compulsive disorder (OCD). This is because Dumirox is not used to treat depression in people under 18 years old.

When taking this type of medication, patients under 18 years old have a higher risk of adverse effects such as suicidal attempts, ideas of suicide, and hostility, such as aggression, confrontational behavior, and irritability.

If your doctor has prescribed Dumirox to a patient under 18 years old to treat another condition other than OCD and wants to discuss this decision, return to your doctor.

If a patient under 18 years old is taking Dumirox, inform your doctor if any of the symptoms listed above progress or if you have complications.

There is no information on the long-term safety of Dumirox in children under 18 years old regarding growth, maturation, and intellectual and behavioral development.

Taking Dumirox with food and drinks

- do not take alcoholic beverages while taking this medication. Alcohol may interact with Dumirox and cause drowsiness and instability.

Pregnancy and breastfeeding

Consult your doctor or pharmacist before using any medication.

Pregnancy

There is limited experience regarding the use of fluvoxamine during pregnancy. Do not take Dumirox if you are pregnant, unless your doctor considers it absolutely necessary. If you are currently taking fluvoxamine and are planning to become pregnant, please consult your doctor to decide whether to change your medication.

Studies in animals have shown that fluvoxamine reduces sperm quality. Theoretically, this could affect fertility, but so far, there has been no observed impact on human fertility.

Make sure your midwife and/or doctor know that you are taking fluvoxamine. If you take it during pregnancy, especially in the last three months of pregnancy, medications like fluvoxamine may increase the risk of a severe condition in newborns, called persistent pulmonary hypertension of the newborn (PPHN), which makes the baby breathe faster and appear blue. These symptoms usually start within the first 24 hours after the baby's birth. If this happens to your baby, you should inform your midwife and/or doctor immediately.

Do not stop treatment with fluvoxamine suddenly. If you have been taking fluvoxamine for the last three months of pregnancy, your baby may have other symptoms at birth, in addition to difficulty breathing or blue skin, such as being unable to sleep or feed properly, being very hot or cold, feeling unwell, crying a lot, stiff or hypotonic muscles, lethargy, drowsiness, tremors, becoming nervous or having seizures. If your baby has any of these symptoms at birth, consult your doctor immediately.

If you take Dumirox in the final stages of 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 know that you are taking Dumirox to advise you.

Breastfeeding

Fluvoxamine passes into breast milk. There is a risk that it may affect the newborn. Therefore, discuss with your doctor whether you should stop breastfeeding or stop taking fluvoxamine.
