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

Efectin ER contains the active substance venlafaxine.
Efectin ER is an antidepressant that belongs to a group of medicines called serotonin and norepinephrine reuptake inhibitors (SNRIs). These medicines are used to treat depression and other conditions, such as anxiety disorders. The mechanism of action of antidepressants is not fully understood, but they may help by increasing the levels of serotonin and norepinephrine in the brain.
Efectin ER is used to treat depression in adults. Efectin 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 correctly. If the patient does not undergo treatment, their condition may not improve, may worsen, and will be much more difficult to treat.

2. Important information before taking Efectin ER

When not to take Efectin 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 monoamine oxidase inhibitor (MAOI) medicines, which are used to treat depression or Parkinson's disease. Taking MAOIs with Efectin ER may cause serious or even life-threatening side effects. Before starting any MAOI medicine, the patient should also wait at least 7 days after stopping Efectin ER (see also "Efectin ER and other medicines" and the information in this section about serotonin syndrome).

Warnings and precautions

Beforestarting treatment with Efectin ER, the patient should discuss it with their doctor or pharmacist:

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

Efectin ER may cause feelings 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 while taking Efectin ER, as it may cause extreme fatigue and loss of consciousness. Taking Efectin ER with alcohol or certain other medicines may worsen 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 thoughts may worsen when first taking antidepressant medicines, as these medicines may start working after 2 weeks, and sometimes later. These thoughts may also occur when reducing the dose or stopping Efectin ER.
The risk of suicidal thoughts 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 years of age with mental disorders who are treated with antidepressant medicines.

If the patient experiences suicidal thoughts or thoughts of 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 relatives or friends for help and ask them to inform them if they notice that the depression or anxiety has worsened or if there are 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 take special care of their oral hygiene.
Diabetes
Efectin ER may affect blood sugar levels, and it may be necessary to adjust the dose of antidiabetic medicines.
Sexual function disorders
Medicines like Efectin ER (SNRIs) may cause sexual function disorders (see section 4). In some cases, these disorders persisted after stopping treatment.

Children and adolescents

Efectin 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 anger). However, the doctor may prescribe this medicine to patients under 18 years of age if they consider it beneficial. If the doctor has prescribed this medicine to a patient under 18 years of age, and the patient has any doubts, they should discuss it with their doctor again. The patient should inform their doctor if any of these symptoms occur or worsen in patients under 18 years of age taking Efectin ER. The long-term safety of Efectin ER in this age group, regarding effects on growth, maturation, and cognitive and behavioral development, has not been established.

Efectin ER and other medicines

The patient should tell their doctor or pharmacist about all medicines they are taking, have recently taken, or plan to take.
The doctor will decide whether to use Efectin 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 Efectin ER. The patient should tell their doctor if they have taken these medicines within the last 14 days (MAOIs; see "Important information before taking Efectin 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 norepinephrine 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 the MAO inhibitor moclobemide (used to treat depression),
  • medicines containing sibutramine (used for weight loss),
  • medicines containing opioids (e.g., buprenorphine, 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 methylene blue (used to treat high levels of methemoglobin 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, and withdrawal).

Subjective and objective symptoms of serotonin syndrome may include: restlessness, hallucinations, loss of coordination, rapid heart rate, 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. Symptoms of neuroleptic malignant syndrome may include fever, rapid heart rate, sweating, muscle stiffness, disorientation, elevated levels of muscle enzymes (detected in blood tests).

In case of suspected serotonin syndrome, the patient should immediately inform their doctor or go to the nearest hospital emergency department.

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

  • antiarrhythmic medicines, such as quinidine, amiodarone, sotalol, or dofetilide (used to treat heart rhythm disturbances),
  • antipsychotic medicines, such as thioridazine (see above - serotonin syndrome),
  • antibiotics, such as erythromycin or moxifloxacin (used to treat bacterial infections),
  • antihistamine medicines (used to treat allergies).

The following medicines may also interact with Efectin ER, and the patient should use them with caution. It is especially important to inform the doctor 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 Efectin ER with food, drink, and alcohol

Efectin ER should be taken with food (see section 3 "How to take Efectin ER").
The patient should not drink alcohol while taking Efectin ER. Taking Efectin ER with alcohol may cause extreme fatigue and loss of consciousness, as well as worsen 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. Efectin ER should only be used after discussing the potential benefits and risks to the unborn child with the doctor.
Taking Efectin ER at the end of pregnancy may increase the risk of severe bleeding from the uterus, occurring shortly after delivery, especially if the patient has a history of bleeding disorders. If the patient is taking Efectin ER, they should inform their doctor or midwife so that they can provide appropriate advice.
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, 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 is taking this medicine during pregnancy, after birth, the child may experience, in addition to breathing difficulties, other symptoms such as poor feeding. 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.
Efectin 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 treatment with Efectin ER.

Driving and using machines

The patient should not drive or operate machinery until they know how the medicine affects them.

Efectin ER 150 contains sodium

The medicine contains less than 1 mmol (23 mg) of sodium per capsule, which means it is essentially "sodium-free".

3. How to take Efectin ER

The patient should always take this medicine exactly as their doctor has told them. If they are unsure, they should ask their doctor or pharmacist.
Typically, the recommended starting dose for depression, generalized anxiety disorder, and social phobia is 75 mg once daily. The doctor may gradually increase this dose if necessary, up to a maximum dose of 375 mg once daily for depression. For panic disorder, treatment should be started with a lower dose (37.5 mg) and gradually increased. The maximum dose for generalized anxiety disorder, social phobia, and panic disorder is 225 mg once daily.
Efectin ER should be taken once daily, at approximately the same time, either in the morning or evening. The capsules should be swallowed whole with a drink of water. They should not be divided, crushed, chewed, or dissolved.
Efectin ER should be taken with food.
The patient should inform their doctor about any liver or kidney problems, as they may need to adjust the dose.
The patient should not stop taking this medicine without consulting their doctor (see "Stopping Efectin ER").

If the patient has taken more than the recommended dose of Efectin ER, they should contact their doctor immediately.
Overdose can be life-threatening, especially when taken with alcohol and/or certain other medicines (see "Efectin ER and other medicines").
Symptoms of possible overdose may include rapid heart rate, changes in consciousness (from drowsiness to coma), vision disturbances, seizures, and vomiting.

Missing a dose of Efectin ER

If the patient misses a dose, they should take it as soon as possible. However, if it is almost time for their next dose, they should skip the missed dose and take only one dose at the usual time. The patient should not take a double dose to make up for a missed dose. The patient should not take more than the daily dose of Efectin ER prescribed by their doctor in a 24-hour period.

Stopping Efectin ER

The patient should not stop taking Efectin ER or reduce the dose without consulting their doctor, even if they feel better. If the doctor decides that it is possible to stop Efectin ER, they will tell the patient how to gradually reduce the dose before completely stopping treatment. When stopping treatment, especially after sudden discontinuation or too rapid dose reduction, the patient may experience side effects, such as suicidal thoughts, aggressive behavior, fatigue, dizziness, feeling empty-headed, headache, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, nervousness, agitation, disorientation, ringing in the ears, tingling or numbness, weakness, sweating, seizures, or flu-like symptoms, vision disturbances, and increased blood pressure (which may cause headaches, dizziness, ringing in the ears, sweating, etc.).
The doctor will advise the patient on how to gradually stop taking Efectin ER. This may take several weeks or months. In some patients, it may be necessary to stop the medicine very slowly over a period of several months or longer. If the patient experiences any of these symptoms or other symptoms that are troublesome, they should consult their doctor.
If the patient has any further doubts about taking this medicine, they should consult their doctor or pharmacist.
