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 with depression and/or anxiety have lower levels of serotonin and noradrenaline in the brain. The exact mechanism of action of antidepressants is not fully understood, but they may help by increasing the levels of serotonin and noradrenaline in the brain.
Alventa is used to treat 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 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 from 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 treatment with any MAOI, 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 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 eye).
- 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, e.g. warfarin (used as an anticoagulant).
- If the patient has increased cholesterol levels.
- 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, during the first few weeks of treatment, cause feelings of restlessness or inability to sit still. If such symptoms occur, inform the treating doctor.
Suicidal thoughts and worsening of depression or anxiety disorders
Patients with depression or anxiety disorders may sometimes have thoughts about self-harm or suicide. These symptoms or behaviours may worsen at the beginning of treatment with antidepressants, as these medicines usually start working only after about 2 weeks, sometimes later. 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 of 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 antidepressants.
If the patient experiences thoughts about self-harm or suicide, they should immediately contact their doctor or go to the nearest hospital.
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 them to inform them if they notice worsening depression or anxiety, or concerning changes in the patient's behaviour.
Sexual dysfunction
Medicines such as Alventa (so-called SSRIs or SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persisted after stopping 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 necessitate 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 manifestations of anger).
Nevertheless, a 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, 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. The long-term safety of the effect 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 any 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 life-threatening condition or reactions resembling neuroleptic malignant syndrome may occur (see section "Possible side effects"), especially when taken 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 (a substance used to treat infections);
- medicines containing the reversible MAOI, moclobemide (a substance used to treat depression);
- medicines containing sibutramine (a substance used for weight loss);
- medicines containing tramadol, fentanyl, buprenorphine, tapentadol, pethidine, or pentazocine (substances used to treat severe pain) (analgesics);
- medicines containing dextromethorphan (used to treat cough);
- medicines containing methadone (used to treat opioid addiction or severe pain);
- medicines containing methylene blue (a substance used to treat high levels of methemoglobin 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);
- antipsychotic medicines (used to treat illnesses with symptoms such as hearing, seeing, and feeling things that do not exist, delusions, abnormal suspiciousness, abnormal perceptions and judgements, 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 changes in blood pressure, hyperreflexia, diarrhoea, coma, nausea, vomiting.
The most severe form of serotonin syndrome may resemble neuroleptic malignant syndrome.
Its symptoms include: fever, rapid heartbeat, sweating, muscle rigidity, disorientation, increased levels of muscle enzymes (detected in blood tests).
If serotonin syndrome is suspected, inform the doctor immediately or go to the nearest hospital emergency department.
If the patient is taking medicines that may affect heart rhythm, they should inform their 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").
During treatment with Alventa, alcohol consumption should be avoided.
Pregnancy, breastfeeding and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to become pregnant, 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 towards the end of pregnancy may increase the risk of severe vaginal bleeding occurring shortly after delivery, especially if the patient has a history of coagulation disorders. If the patient is taking Alventa, she should inform her doctor or midwife so they can provide appropriate advice.
Inform the 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 is characterized by rapid breathing and cyanosis. These symptoms usually appear within the first day after birth. If such symptoms occur in the newborn, contact the 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 problems with sucking. If the patient is concerned about such symptoms in the newborn, she should contact the doctor and (or) midwife, who will be able to provide appropriate advice.
Alventa passes into breast milk. There is a risk of the medicine affecting the infant. Therefore, this issue should be discussed with the doctor, and the doctor will decide whether breastfeeding should be discontinued or whether treatment with this medicine should be stopped.
Driving and using machines
Do not drive or operate machinery until the effect of this medicine on the patient's body is known.
Alventa contains sucrose
If the patient has been told by a doctor that they have an intolerance to certain sugars, they should consult their doctor before taking this medicine.
