1. What is Symfaxin ER and what is it used for

Symfaxin ER contains the active substance venlafaxine.
Symfaxin ER is an antidepressant that belongs to a group of medicines called serotonin and noradrenaline reuptake inhibitors (SNRIs). These medicines are used to treat depression and other conditions, such as anxiety disorders. It is thought that in people with depression and/or anxiety, there is a lower level of serotonin and noradrenaline in the brain.
The mechanism of action of antidepressants is not fully understood, but they may help by increasing the levels of serotonin and noradrenaline in the brain.
Symfaxin ER is used to treat depression in adults. Symfaxin ER is also indicated for the treatment of the following anxiety disorders in adults: generalized anxiety disorder, social phobia (fear or avoidance of social situations), and panic disorder (panic attacks). For the patient to feel better, it is essential that the treatment of depression and anxiety disorders is carried out properly. If the patient does not undergo treatment, their condition may not improve, it may worsen, and it will be much more difficult to treat.

2. Important information before taking Symfaxin ER

When not to take Symfaxin ER:

  • If the patient is allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6).
  • If the patient is taking, or has taken within the last 14 days, any medicines known as irreversible monoamine oxidase inhibitors (MAOIs), which are used to treat depression or Parkinson's disease. Taking irreversible MAOIs with Symfaxin ER may cause serious or even life-threatening side effects. Before starting to take any MAOI medicine, the patient should also wait at least 7 days after stopping taking Symfaxin ER (see also section "Symfaxin ER and other medicines" and the information in that section about serotonin syndrome).

"Symfaxin ER and other medicines" and the information in that section about serotonin syndrome.

Warnings and precautions

Before starting to take Symfaxin ER, the patient should discuss it with their doctor or pharmacist:

  • If the patient is taking other medicines that, when taken with Symfaxin ER, may increase the risk of developing serotonin syndrome (see section "Symfaxin ER and other medicines").
  • If the patient has eye diseases, such as certain types of glaucoma (increased pressure in the eyeball).
  • If the patient has had high blood pressure in the past.
  • If the patient has had heart disease in the past.
  • If the patient has had arrhythmias in the past.
  • If the patient has had seizures (epilepsy) in the past.
  • If the patient has had low sodium levels in the blood (hyponatremia) in the past.
  • If the patient has a tendency to bruise or bleed (a history of bleeding disorders), or if they are taking other medicines that may increase the risk of bleeding, such as warfarin (used to prevent blood clots).
  • If the patient is pregnant (see "Pregnancy and breastfeeding").
  • If the patient or anyone in their family has had mania (a feeling of excessive excitement or euphoria) or bipolar disorder in the past.
  • If the patient has had aggressive behavior in the past.

Symfaxin ER may cause a feeling of restlessness or an inability to sit or stand still during the first few weeks of treatment. If such symptoms occur, the patient should inform their doctor.
The patient should not drink alcohol during treatment with Symfaxin ER, as it may cause extreme fatigue and loss of consciousness. Taking Symfaxin ER with alcohol and/or certain other medicines may increase the severity of symptoms of depression and other conditions, such as anxiety disorders.
Suicidal thoughts and worsening of depression or anxiety disorders
People with depression and/or anxiety disorders may sometimes have thoughts of self-harm or suicide. Such symptoms or behavior may worsen at the start of treatment with antidepressants, as these medicines start to work usually after 2 weeks, and sometimes later.
The risk of suicidal thoughts or self-harm is higher if:

  • the patient has had suicidal thoughts or self-harm in the past,
  • the patient is a young adult; clinical trial data indicate an increased risk of suicidal behavior in people under 25 with mental disorders who are treated with antidepressants.

If the patient experiences suicidal thoughts or self-harm, they should contact their doctor or go to the hospital immediately.
It may be helpful to inform relatives or friends about the depression or anxiety disorder and ask them to read this leaflet. The patient may ask their relatives or friends for help and ask them to inform them if they notice that the depression or anxiety has worsened and if there are any worrying changes in behavior.
Dry mouth
Dry mouth was reported by 10% of patients treated with venlafaxine. It may increase the risk of tooth decay. Therefore, the patient should pay special attention to oral hygiene.
Diabetes
Symfaxin ER may affect blood sugar levels, and it may be necessary to adjust the dose of antidiabetic medicines.
Medicines such as Symfaxin ER (so-called SSRIs or SNRIs) may cause sexual dysfunction (see section 4). In some cases, these symptoms have persisted after stopping treatment.

Children and adolescents

Symfaxin ER should not be used in children and adolescents under 18 years of age. It should also be noted that patients under 18 years of age who take medicines of this class are at increased risk of side effects, such as suicidal attempts, suicidal thoughts, and hostility (especially aggression, rebellious behavior, and manifestations of anger). However, the doctor may prescribe Symfaxin ER to patients under 18 years of age if they consider it beneficial for them. If the doctor has prescribed Symfaxin ER to a patient under 18 years of age, in case of any doubts, the patient should consult their doctor to discuss it. The patient should inform their doctor if any of these symptoms occur or worsen in patients under 18 years of age taking Symfaxin ER. The long-term safety of Symfaxin ER on growth, maturation, and cognitive and behavioral development in this age group has not been established.

Symfaxin ER and other medicines

The patient should tell their doctor or pharmacist about all medicines they are taking, have recently taken, or might take.
The doctor will decide whether to use Symfaxin ER with other medicines.
The patient should not start or stop taking other medicines, including those available without a prescription, herbal products, or dietary supplements, without consulting their doctor or pharmacist first.

  • Monoamine oxidase inhibitors, used to treat depression or Parkinson's disease, must not be taken with Symfaxin ER. The patient should tell their doctor if they have taken these medicines within the last 14 days (see section "Important information before taking Symfaxin ER").
  • Serotonin syndrome: During treatment with venlafaxine, a life-threatening or neuroleptic malignant syndrome-like reaction may occur, especially when taken with other medicines. Examples of such medicines include:
    • triptans (used to treat migraine headaches);
    • other medicines used to treat depression, such as selective serotonin reuptake inhibitors (SSRIs), serotonin and noradrenaline reuptake inhibitors (SNRIs), tricyclic antidepressants, or lithium-containing medicines;
    • medicines containing amphetamine derivatives [used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity];
    • medicines containing the antibiotic linezolid (used to treat infections);
    • medicines containing moclobemide, an MAO inhibitor (used to treat depression);
    • medicines containing sibutramine (used for weight loss);
  • medicines containing tramadol, fentanyl, tapentadol, pethidine, or pentazocine (used to treat severe pain);
  • medicines containing dextromethorphan (used to treat cough);
  • medicines containing methadone (used to treat opioid dependence or severe pain);
  • medicines containing methylthioninium chloride (methylene blue) (used to treat high methemoglobin levels in the blood);
  • medicines containing St. John's Wort (Hypericum perforatum, herbal products or dietary supplements, used to treat mild depression);
  • medicines containing tryptophan (used for sleep problems and depression);
  • antipsychotic medicines (used to treat conditions with symptoms such as hearing, seeing, or feeling things that do not exist, delusions, unnatural suspicion, unclear thinking, withdrawal).

The subjective and objective symptoms of serotonin syndrome may include: restlessness, hallucinations, loss of coordination, rapid heartbeat, elevated body temperature, rapid changes in blood pressure, overreactivity, diarrhea, coma, nausea, vomiting.
The most severe form of serotonin syndrome may resemble neuroleptic malignant syndrome (NMS). The symptoms of NMS may include fever, rapid heartbeat, sweating, muscle stiffness, disorientation, elevated levels of muscle enzymes (detected in blood tests),

In case of suspected serotonin syndrome, the patient should immediately tell their doctor or go to the hospital.

If the patient is taking medicines that may affect heart rhythm, they should tell their doctor. Examples of such medicines include:

  • anti-arrhythmic medicines, such as quinidine, amiodarone, sotalol, or dofetilide (used to treat arrhythmias);
  • antipsychotic medicines, such as thioridazine (see above - serotonin syndrome);
  • medicines used to treat bacterial infections, such as erythromycin or moxifloxacin;
  • antihistamine medicines (used to treat allergies).

The following medicines may also interact with Symfaxin ER, and the patient should use them with caution. It is especially important to inform the doctor or pharmacist if the patient is taking medicines containing:

  • ketokonazole (an antifungal medicine);
  • haloperidol or risperidone (medicines used to treat mental disorders);
  • metoprolol (a beta-blocker used to treat high blood pressure and heart disease).

Taking Symfaxin ER with food, drink, and alcohol

Symfaxin ER should be taken with food (see section 3 "How to take Symfaxin ER").
The patient should not drink alcohol during treatment with Symfaxin ER. Taking Symfaxin ER with alcohol may cause extreme fatigue and loss of consciousness, as well as worsening of symptoms of depression and other conditions, such as anxiety disorders.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a baby, they should consult their doctor or pharmacist before taking this medicine. Symfaxin ER should only be used after discussing the potential benefits and risks to the unborn child with the doctor.
The patient should inform their doctor and/or midwife if they are taking Symfaxin ER. Similar medicines (SSRIs) taken during pregnancy may increase the risk of a serious condition in children and/or infants, called persistent pulmonary hypertension of the newborn (PPHN), which causes rapid breathing and bluish discoloration. These symptoms usually occur within 24 hours of birth. If the patient notices such symptoms in their child, they should contact the midwife and/or doctor immediately.
If the patient took this medicine during pregnancy, the newborn may experience difficulties with breathing or other symptoms, such as poor sucking. If the patient is concerned about such symptoms in their newborn, they should contact their doctor and/or midwife, who will be able to provide appropriate advice.
Taking Symfaxin ER at the end of pregnancy may increase the risk of severe bleeding from the uterus, which occurs shortly after delivery, especially if the patient has a history of bleeding disorders. If the patient is taking Symfaxin ER, they should inform their doctor or midwife so that they can provide appropriate advice.
Symfaxin ER passes into breast milk. There is a risk of affecting the child. Therefore, the patient should discuss this with their doctor, who will decide whether to stop breastfeeding or stop Symfaxin ER treatment.

Driving and using machines

The patient should not drive or operate machinery until they know how Symfaxin ER affects them.

Missing a dose of Symfaxin ER

Stopping Symfaxin ER treatment

The patient should not stop treatment or reduce the dose of Symfaxin ER without consulting their doctor, even if they feel better.
