1. What Alventa is and what it is used for

Alventa contains the active substance - venlafaxine.
Alventa is an antidepressant medicine belonging to a group of medicines called serotonin and noradrenaline reuptake inhibitors (SNRIs). Medicines in this group are used in the treatment of depression and other conditions such as anxiety disorders. It is believed that people experiencing depression and/or anxiety have lower levels of serotonin and noradrenaline in the brain. The mechanism of action of antidepressant medicines is not fully understood, but they may help by increasing the levels of serotonin and noradrenaline in the brain.
Alventa is used in the treatment of depression in adults. Alventa 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 important that treatment for depression and anxiety disorders is properly managed. If treatment is not initiated, the patient's condition may not improve, may worsen, and will become significantly more difficult to treat.

2. Important information before taking Alventa

When not to take Alventa

  • If the patient is allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6).
  • If the patient is currently taking or has taken within the last 14 days any medicine belonging to the group of irreversible monoamine oxidase inhibitors (MAOIs) used to treat depression or Parkinson's disease. Taking irreversible MAOIs together with Alventa may cause severe or even life-threatening adverse reactions. Also, before starting any medicine from the MAOI group, the patient should wait at least 7 days after stopping Alventa (see also section "Alventa and other medicines" and information in this section regarding serotonin syndrome).

Warnings and precautions
Before starting treatment with Alventa, discuss this with your doctor or pharmacist:

  • If the patient is taking other medicines which, when taken together with Alventa, may increase the risk of serotonin syndrome (see section "Alventa and other medicines").
  • If the patient suffers from eye disorders, such as certain types of glaucoma (increased pressure in the eyeball).
  • If the patient has previously had high blood pressure.
  • If the patient has previously had heart diseases.
  • If the patient has previously had heart rhythm disorders.
  • If the patient has previously had seizures (epilepsy).
  • If the patient has previously had low sodium levels in the blood (hyponatraemia).
  • If the patient has a tendency to bruise easily or to bleed (bleeding disorders in the past), or if the patient is pregnant (see section "Pregnancy, breastfeeding and fertility") or if the patient is taking other medicines that may increase the risk of bleeding, such as warfarin (used as an anticoagulant).
  • If the patient's cholesterol levels have increased.
  • If the patient or anyone in their family has previously had mania or bipolar disorder (feelings of excessive excitement or euphoria).
  • If the patient has previously exhibited aggressive behaviour.

Alventa may cause feelings of restlessness or an inability to sit still during the first few weeks of treatment. If such symptoms occur, inform your doctor immediately.
Do not consume alcohol while being treated with Alventa, as this may cause extreme fatigue and loss of consciousness. Concurrent use with alcohol and (or) certain medicines may worsen symptoms of depression and other medical conditions, such as anxiety disorders.

Suicidal thoughts and worsening of depression or anxiety disorders
Patients with depression or anxiety disorders may sometimes experience thoughts about self-harm or suicide. These symptoms or behaviours may worsen at the beginning of treatment with antidepressant medicines, as these medicines usually take about 2 weeks, sometimes longer, to start working. Such thoughts may also occur when the dose is reduced or when Alventa is discontinued.
The following suicidal thoughts or thoughts of self-harm are more likely in:

  • Patients who previously had thoughts about self-harm or suicide;
  • Young adult patients. Clinical trial data show an increased risk of suicidal behaviour in individuals under 25 years of age with psychiatric disorders who were treated with antidepressant medicines.

If the patient develops thoughts about self-harm or suicide, contact a doctor immediately or go to the nearest hospital.
It may be helpful to inform family members or friends about the depression or anxiety disorder and ask them to read this leaflet. The patient may ask them to inform him/her if they notice that depression or anxiety worsens or if there are worrying changes in the patient's behaviour.

Sexual dysfunction
Medicines such as Alventa (so-called SSRIs or SNRIs) may cause sexual dysfunction symptoms (see section 4). In some cases, these symptoms persisted after discontinuation of treatment.

Dry mouth
Dry mouth is reported by 10% of patients treated with venlafaxine. This may increase the risk of dental caries. Therefore, special attention should be paid to oral hygiene.

Diabetes
Alventa may alter blood glucose levels and therefore may require adjustment of the dose of antidiabetic medicines.

Children and adolescents
Alventa should not be used in children and adolescents under 18 years of age.
It should also be emphasized that patients under 18 years of age who take medicines from this group are at increased risk of adverse reactions such as suicide attempts, suicidal thoughts, and hostility (particularly aggression, defiant behaviour, and anger).
Nevertheless, a doctor may prescribe this medicine to patients under 18 years of age if he/she considers it beneficial for them. If a doctor has prescribed this medicine to a patient under 18 years of age, any doubts should be discussed again with the doctor. Inform the doctor if any of the above-mentioned symptoms occur or worsen in patients under 18 years of age taking Alventa. Long-term safety regarding the impact on growth, maturation, and cognitive and behavioural development in this age group has not yet been established.

Alventa and other medicines
Tell your doctor or pharmacist about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take.
The treating doctor will decide whether Alventa can be taken together with other medicines.
Do not start or stop taking other medicines, including over-the-counter medicines, natural or herbal remedies, without first consulting your doctor or pharmacist.

  • Monoamine oxidase inhibitors used to treat depression or Parkinson's disease must not be taken with Alventa. Inform your doctor if the patient has taken these medicines within the last 14 days (MAOIs; see section "Important information before taking Alventa").
  • Serotonin syndrome: During treatment with venlafaxine, a potentially life-threatening condition or reactions resembling neuroleptic malignant syndrome (see section "Possible side effects") may occur, especially when used concomitantly with medicines such as:
  • Triptans (substances used for migraine headaches);
  • Other medicines used to treat depression, e.g., selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, or medicines containing lithium;
  • 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 reversible MAOI 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 addiction or severe pain);
  • Medicines containing methylene blue (used to treat high methemoglobin levels in the blood);
  • Medicines containing St. John's wort (Hypericum perforatum), natural or herbal remedies used to treat mild depression;
  • Medicines containing tryptophan (used for sleep problems and depression);
  • Antipsychotics (used to treat diseases with symptoms such as hearing, seeing, or feeling things that do not exist, delusions, abnormal suspiciousness, abnormal perceptions and judgments, social withdrawal).

Subjective and objective symptoms of serotonin syndrome may include a combination of the following:
agitation, hallucinations, loss of coordination, rapid heartbeat, elevated body temperature, rapid fluctuations in blood pressure, hyperreflexia, diarrhoea, lethargy, nausea, vomiting.
The most severe form of serotonin syndrome may resemble neuroleptic malignant syndrome.
Its symptoms include: fever, rapid heartbeat, sweating, muscle rigidity, confusion, increased muscle enzyme levels (detected in blood tests).
If serotonin syndrome is suspected, contact your doctor immediately or go to the nearest hospital emergency department.

If the patient is taking medicines that may affect heart rhythm, inform the doctor. Examples of such medicines:

  • Antiarrhythmics such as quinidine, amiodarone, sotalol, or dofetilide (used to treat heart rhythm disorders),
  • Antipsychotics such as thioridazine (see above - serotonin syndrome),
  • Antibiotics such as erythromycin or moxifloxacin (used to treat bacterial infections),
  • Antihistamines (used to treat allergies).

The following medicines may also interact with Alventa and therefore should be used with caution. It is particularly important to inform the doctor if the patient is taking medicines containing:

  • Ketoconazole (an antifungal medicine);
  • Haloperidol or risperidone (medicines used to treat psychiatric disorders);
  • Metoprolol (a beta-blocker used to treat high blood pressure and heart diseases).

Alventa with food, drink and alcohol
Alventa should be taken with food (see section 3 "How to take Alventa").
Do not consume alcohol while being treated with Alventa. Concurrent use with alcohol may cause extreme fatigue and loss of consciousness and may worsen symptoms of depression and other medical conditions, such as anxiety disorders.

Pregnancy, breastfeeding and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a baby, she should consult her doctor or pharmacist before taking this medicine.
Alventa should only be used after discussing with the doctor the potential benefits and potential risks to the unborn child.
Taking Alventa late in pregnancy may increase the risk of severe vaginal bleeding occurring shortly after delivery, especially if the patient has a history of blood clotting disorders. If the patient is taking Alventa, she should inform her doctor or midwife so they can provide appropriate advice.
Inform your doctor and (or) midwife about taking Alventa. Taking similar medicines during pregnancy [such as serotonin reuptake inhibitors (SSRIs)] may increase the risk of serious complications in the newborn, known as persistent pulmonary hypertension of the newborn (PPHN), which manifests as rapid breathing and cyanosis. These symptoms usually appear within the first 24 hours after birth. If such symptoms occur in the newborn, contact your doctor and (or) midwife immediately.
If the patient takes this medicine during pregnancy, her newborn may experience, in addition to breathing difficulties, other symptoms such as feeding problems. If the patient is concerned about such symptoms in the newborn, she should contact her doctor and (or) midwife, who will be able to provide appropriate advice.
Alventa passes into breast milk. There is a risk that the medicine may affect the infant. Therefore, this issue should be discussed with the doctor, and the doctor will decide whether breastfeeding should be discontinued or treatment with this medicine stopped.

Driving and operating machinery
Do not drive or operate machinery until you know how this medicine affects you.

Alventa contains sucrose
If the patient has been told by a doctor that he or she has an intolerance to certain sugars, he or she should consult the doctor before taking this medicine.

be initiated at a lower dose (37.5 mg), which may then be gradually increased. The maximum dose for
the treatment of generalized anxiety disorders, social phobia, and panic disorder is 225 mg per day.
Alventa should be taken every day at approximately the same time, regardless of whether it is taken
in the morning or evening. The capsules must be swallowed whole with liquid.
