1. What Axyven is and what it is used for

Axyven contains the active substance venlafaxine. Axyven is an antidepressant that belongs to a group of medicines called serotonin and norepinephrine reuptake inhibitors (SNRIs). This group of medicines is 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. Axyven is used to treat adult patients with depression. Axyven is also used to treat the following anxiety disorders in adult patients: generalized anxiety disorder, social phobia (fear or avoidance of social situations), and panic attacks (panic disorder). It is important for the patient's well-being that the treatment of depression and anxiety disorders is carried out properly. If the patient does not receive treatment, their condition may not improve, may worsen, and may become more difficult to treat.

2. What you need to know before you take Axyven

When not to take Axyven:

• If you are allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6).
• If you are taking, or have taken within the last 14 days, any medicines known as irreversible monoamine oxidase inhibitors (IMAOs) used to treat depression or Parkinson's disease. Taking irreversible IMAOs with Axyven may cause serious or even life-threatening side effects. Also, before starting to take any medicines that are part of the IMAO group, the patient should wait at least 7 days after stopping Axyven (see also "Axyven with other medicines" and information in "Serotonin syndrome").

Side effects can be serious. If you experience any of the following, stop taking Axyven and contact a doctor or go to the emergency department at your nearest hospital immediately.

Warnings and precautions

Before startingtreatment with Axyven, you should discuss this with your doctor or pharmacist:

• If you are taking other medicines that, when taken with Axyven, may increase the risk of developing serotonin syndrome (see "Axyven with other medicines").
• If you have problems with swallowing, stomach or intestinal problems that reduce your ability to swallow or pass food through proper bowel movements.
• If you have eye problems, such as certain types of glaucoma (increased pressure in the eyeball).
• If you have a history of high blood pressure.
• If you have had heart problems in the past.
• If you have had heart rhythm problems.
• If you have had seizures (epilepsy) in the past.
• If you have had low sodium levels in the blood (hyponatremia) in the past.
• If you have had bleeding disorders (tendency to bruise or bleed) or if you are taking other medicines that may increase the risk of bleeding, such as warfarin (used to prevent blood clots), or if you are pregnant (see "Pregnancy, breastfeeding, and fertility").
• If you or anyone in your family has had mania or bipolar disorder (feeling excessively excited or euphoric) in the past.
• If you have had aggressive behavior in the past.

During the first few weeks of treatment with Axyven, you may experience restlessness or an inability to sit or stand still. If such symptoms occur, you should inform your doctor. Do not drink alcohol while taking Axyven, as it may cause extreme fatigue and loss of consciousness. Taking Axyven with alcohol and/or certain other medicines may increase the severity of depression and other conditions, such as anxiety disorders. Suicidal thoughts and worsening of depression or anxiety disorders Patients with depression and/or anxiety disorders may sometimes have thoughts of self-harm or suicide. These thoughts may worsen when starting to take antidepressants, as these medicines usually start working after two weeks or sometimes later. These thoughts may also occur when the dose of Axyven is reduced or when treatment with Axyven is stopped. Such thinking may be more likely if:

• You have had suicidal thoughts or self-harm in the past.
• You are a young adult. Data from clinical trials have shown an increased risk of suicidal behavior in young adults (under 25 years of age) with mental health conditions who were treated with antidepressants.

If you experience suicidal thoughts or thoughts of self-harm, you should contact your doctor or go to the emergency department at your nearest hospital immediately. It may be helpful to inform your relatives or friends about your depression or anxiety disorder and ask them to read this leaflet. You may want to ask your relatives or friends to tell you if they notice that your depression or anxiety has worsened or if you have developed worrying changes in your behavior. Dry mouth Dry mouth was reported by 10% of patients treated with venlafaxine. This may increase the risk of tooth decay. Therefore, you should pay special attention to oral hygiene. Patients with diabetes The blood sugar level may change when taking Axyven. Therefore, the dosage of antidiabetic medicines may need to be adjusted. Sexual dysfunction Medicines like Axyven (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

Axyven should not normally be used in children and adolescents under 18 years of age. It is also known that in the case of this class of medicines, patients under 18 years of age are at increased risk of developing side effects such as suicidal attempts, suicidal thoughts, and hostility (especially aggression, rebellious behavior, and manifestations of anger). Despite this, the doctor may prescribe this medicine to patients under 18 years of age if they consider it to be in their best interest. If the doctor has prescribed this medicine to a patient under 18 years of age and there are any doubts, you should consult the doctor. You should inform the doctor if any of the following symptoms occur or worsen in patients under 18 years of age taking Axyven. Additionally, as of now, there is a lack of long-term safety data on the use of this medicine in this age group regarding the impact on growth, maturation, and cognitive and behavioral development.

Axyven with other medicines

Tell your doctor or pharmacist about all the medicines you are taking now or have taken recently, as well as any medicines you plan to take. Your doctor will decide whether to use Axyven with other medicines. Do not start or stop taking other medicines, including those available without a prescription, herbal, or natural remedies, without consulting your doctor or pharmacist first.

• Do not takemonoamine oxidase inhibitors (used to treat depression or Parkinson's disease) at the same time as Axyven. Tell your doctor if you have taken these medicines in the last 14 days (IMAO; see "Important information before taking Axyven").
• Serotonin syndrome:A potentially life-threatening or neuroleptic malignant syndrome-like reaction (see section 4) may occur during treatment with venlafaxine, especially when taken with other medicines.

Examples of such medicines include:

• Tryptans (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 moclobemide, IMAO (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 levels of methemoglobin in the blood).
• Medicines containing St. John's Wort (Hypericum perforatum, herbal or natural remedies used to treat mild depression).
• Medicines containing tryptophan (used for sleep problems and depression).
• Antipsychotic medicines (used to treat symptoms such as hearing, seeing, or feeling things that do not exist, delusional beliefs, unusual suspiciousness, unclear reasoning, and withdrawal behavior).

Subjective and objective symptoms of serotonin syndrome may include a combination of the following symptoms: restlessness, hallucinations, loss of coordination, accelerated heart rate, elevated body temperature, rapid changes in blood pressure, hyperactivity, diarrhea, coma, nausea, vomiting. In its most severe form, serotonin syndrome can resemble neuroleptic malignant syndrome. Objective and subjective symptoms may include a combination of fever, accelerated heart rate, sweating, severe muscle stiffness, disorientation, and increased levels of muscle enzymes (measured in a blood test).

In case of suspected serotonin syndrome, seek medical attention immediately.

If you are taking medicines that may affect your heart rhythm, you should tell your doctor. Examples of such medicines include:

• Antiarrhythmic medicines, such as quinidine, amiodarone, sotalol, or dofetilide (used to treat heart rhythm disorders).
• Antipsychotic medicines, 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 Axyven, so you should use them with caution. It is especially important to inform your doctor or pharmacist if you are taking medicines containing:

• Ketoconazole (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).

Axyven with food, drink, and alcohol

Axyven should be taken with food (see section 3, "How to take Axyven"). Do not drink alcohol while taking Axyven. Taking Axyven with alcohol may cause extreme fatigue and loss of consciousness, as well as worsening of depression and other conditions, such as anxiety disorders.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a baby, ask your doctor for advice before taking this medicine. You should only take Axyven after discussing the potential benefits and risks with your doctor. Make sure your doctor and/or midwife know that you are taking Axyven. Taking similar medicines (SSRIs) during pregnancy may increase the risk of the baby developing a condition called persistent pulmonary hypertension of the newborn (PPHN), which is characterized by rapid breathing and bluish discoloration. These symptoms usually occur within the first 24 hours after birth. If such symptoms occur in the newborn, you should contact your doctor and/or midwife immediately. Taking Axyven late in pregnancy may increase the risk of severe bleeding from the vagina, which occurs shortly after delivery, especially if you have a history of bleeding disorders. If you are taking Axyven, you should inform your doctor or midwife so that they can provide you with appropriate advice. If you take this medicine during pregnancy, your baby may experience breathing difficulties and other symptoms, such as feeding problems, after birth. If you are concerned about such symptoms in your newborn after birth, you should contact your doctor and/or midwife, who will be able to provide you with appropriate advice. Axyven passes into breast milk. There is a risk of an effect on the baby. Therefore, you should discuss this with your doctor, and your doctor will decide whether to stop breastfeeding or stop treatment with this medicine.

Driving and using machines

Do not drive or operate any tools or machines until you know how Axyven affects you.

Axyven contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

3. How to take Axyven

Overdose can be life-threatening, especially when taken with alcohol and/or certain other medicines (see "Axyven with other medicines"). Symptoms of possible overdose may include accelerated heart rate, disturbances of consciousness (from drowsiness to coma), visual disturbances, seizures or convulsions, and vomiting.

Forgetting to take a dose of Axyven

Stopping Axyven treatment

Do not stop taking Axyven without consulting your doctor, even if you feel better. If your doctor decides that you can stop taking Axyven, they will tell you how to gradually reduce the dose before completely stopping treatment. When stopping Axyven, especially when stopping treatment abruptly or reducing the dose too quickly, you may experience side effects. Some patients may experience symptoms such as suicidal thoughts, aggression, fatigue, dizziness, headache, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, nervousness, agitation, disorientation, ringing in the ears, or tingling, and rarely, electric shock-like sensations, weakness, sweating, seizures, or flu-like symptoms. Your doctor will advise you on how to gradually stop taking Axyven. This may take several weeks or months. In some patients, it may be necessary to stop the medicine very gradually over several months or longer. If you experience any of these symptoms or other symptoms that are troublesome to you, you should consult your doctor.
