1. What is Venlabrain Retard and what is it used for

Venlabrain Retard contains the active substance venlafaxine.

Venlabrain Retard is an antidepressant that belongs to a group of medicines called serotonin and noradrenaline reuptake inhibitors (SNRIs). This group of medicines is used to treat depression and other conditions such as anxiety disorders. It is not fully understood how antidepressants work, but they may help to increase the levels of serotonin and noradrenaline in the brain.

Venlabrain Retard is a treatment for adults with depression. It is also a treatment for adults with the following anxiety disorders: generalized anxiety disorder, social anxiety disorder (fear or avoidance of social situations), panic disorder (panic attacks). Treating depressive and anxiety disorders properly is important to help you feel better. If left untreated, your condition may not improve or may get worse and become more difficult to treat.

2. What you need to know before you take Venlabrain Retard

Do not takeVenlabrainRetard

• If you are allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6).
• If you are also taking, or have taken within the last 14 days, any medicinal product known as an irreversible monoamine oxidase inhibitor (MAOI) used to treat depression or Parkinson's disease. Taking an irreversible MAOI with Venlabrain Retard can cause serious or even life-threatening side effects. Also, you must wait at least 7 days after stopping Venlabrain Retard before taking any irreversible MAOI (see also the section "Taking Venlabrain Retard with other medicines" and the information in this section on "Serotonin Syndrome").

Warnings and precautions

Consult your doctor or pharmacist beforeyou take Venlabrain Retard

• If you are taking other medicines that, when taken with Venlabrain Retard, could increase the risk of developing serotonin syndrome (see the section "Taking Venlabrain Retard with other medicines").
• If you have problems with swallowing or have a condition that reduces your ability to swallow or pass food through your digestive system.
• If you have eye problems, such as certain types of glaucoma (increased pressure in the eye).
• If you have a history of high blood pressure.
• If you have been told you have an abnormal heart rhythm.
• If you have a history of heart problems.
• If you have a history of seizures (fits).
• If you have a history of low sodium levels in your blood (hyponatremia).
• If you have a history of bleeding disorders (tendency to develop bruises or bleeding easily), or if you are using other medicines that may increase the risk of bleeding (e.g., warfarin to prevent blood clots), or if you are pregnant (see "Pregnancy and breastfeeding").
• If you have a history of, or if a family member has had, mania or bipolar disorder (feeling overexcited or euphoric).
• If you have a history of aggressive behavior.

Venlabrain Retard may cause a feeling of restlessness or difficulty sitting or standing still during the first few weeks of treatment. You should consult your doctor if this happens to you.

Do not drink alcohol while taking this medicine, as it may cause extreme tiredness and unconsciousness. Taking it with certain medicines and/or alcohol may worsen symptoms of depression and other conditions, such as anxiety disorders.

Thoughts of suicide and worsening of your depression or anxiety disorder

If you are depressed and/or have an anxiety disorder, you may sometimes have thoughts of harming or killing yourself. These thoughts may increase when you first start taking antidepressants, because all these medicines take time to work, usually around 2 weeks, but sometimes longer. These thoughts may also occur when your dose is reduced or when you stop taking Venlabrain Retard.

You are more likely to have these thoughts if:

• You have previously had thoughts of suicide or harming yourself.
• You are a young adult. Information from clinical trials has shown an increased risk of suicidal behavior in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant.

If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.

Dry mouth

Dry mouth has been reported in 10% of patients treated with venlafaxine. This may increase the risk of tooth decay. Therefore, you should be careful with your oral hygiene.

Diabetes

Your blood glucose levels may be altered due to Venlabrain Retard. The doses of your diabetes medicines may need to be adjusted.

Sexual problems

Some medicines of the same group as Venlabrain Retard (called SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms have persisted after stopping treatment.

Children and adolescents

Venlabrain Retard should not normally be used in the treatment of children and adolescents under 18 years. Also, you should know that in patients under 18 years, there is an increased risk of adverse effects such as suicidal attempts, suicidal thoughts, and hostility (mainly aggression, confrontation, and irritability) when they take this type of medicine. However, your doctor may prescribe this medicine to a patient under 18 years when they decide that it is the best option for the patient. If your doctor has prescribed this medicine to a patient under 18 years and you want to discuss this, please go back to your doctor. You should tell your doctor if any of the above symptoms develop or get worse when these patients under 18 years are taking Venlabrain Retard. Also, the long-term effects of this medicine on safety, growth, maturation, and cognitive and behavioral development have not yet been demonstrated.

Taking Venlabrain Retard with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Your doctor will decide if you can take Venlabrain Retard with other medicines.

Do not start or stop taking any medicines, including those that can be bought without a prescription, herbal remedies, and supplements, before checking with your doctor or pharmacist.

• Irreversible monoamine oxidase inhibitors, which are used to treat depression or Parkinson's disease, must not be taken with Venlabrain Retard. Tell your doctor if you have taken these medicines in the last 14 days (MAOIs: see section "What you need to know before you take Venlabrain Retard").
• Serotonin Syndrome: a potentially life-threatening condition, or reactions similar to Neuroleptic Malignant Syndrome (NMS) (see section "Possible side effects"), may occur with venlafaxine treatment, particularly when taken with other medicines.

Examples of these medicines include:

• Triptans (used to treat migraine).
• Other medicines for treating depression, for example, SSRIs, SNRIs, tricyclic antidepressants, medicines containing lithium.
• Medicines containing amphetamines (used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity).
• Medicines containing the antibiotic linezolid (used to treat infections).
• Medicines containing moclobemide, a reversible MAOI (used to treat depression).
• Medicines containing sibutramine (used for weight loss).
• Medicines containing opioids (e.g., buprenorphine, tramadol, fentanyl, tapentadol, pethidine, or pentazocine) (for the treatment of severe pain).
• Medicines containing dextromethorphan (used to treat coughs).
• Medicines containing methadone (used to treat addiction to opioid drugs or severe pain).
• Medicines containing methylthioninium chloride (methylene blue) (used to treat high levels of methemoglobin in the blood).
• Products containing St. John's Wort (also known as Hypericum perforatum, a herbal remedy used to treat mild depression).
• Products containing tryptophan (used for problems such as sleep and depression).
• Antipsychotics (used to treat disorders with symptoms such as hearing, seeing, or feeling things that are not there, mistaken beliefs, unusual suspiciousness, confused reasoning, and withdrawal into oneself).

The signs and symptoms of serotonin syndrome may include a combination of the following: restlessness, hallucinations, loss of coordination, rapid heartbeat, increased body temperature, rapid changes in blood pressure, overactive reflexes, diarrhea, coma, nausea, vomiting.

In its most severe form, serotonin syndrome can resemble Neuroleptic Malignant Syndrome (NMS). Signs and symptoms of NMS may include a combination of fever, rapid heartbeat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (measured by a blood test).

If you think you are suffering from serotonin syndrome, inform your doctor immediately or go to the emergency department of your nearest hospital.

You must tell your doctor if you are taking medicines that may affect your heart rhythm.

These include:

• Anti-arrhythmics such as quinidine, amiodarone, sotalol, and dofetilide (used to treat irregular heartbeat).
• Antipsychotics such as thioridazine (see also Serotonin Syndrome above).
• Antibiotics such as erythromycin or moxifloxacin (used to treat bacterial infections).
• Antihistamines (used to treat allergies).

The following medicines may also interact with Venlabrain Retard and should be used with caution. It is especially important to tell your doctor or pharmacist if you are taking medicines that contain:

• Ketoconazole (an antifungal medicine)
• Haloperidol or risperidone (for treating psychiatric conditions)
• Metoprolol (a beta-blocker for treating high blood pressure and heart problems)

Taking Venlabrain Retard with food, drinks, and alcohol

Venlabrain Retard should be taken with food (see section 4.3 "How to take Venlabrain Retard"). Do not drink alcohol during treatment with this medicine. Taking it with alcohol may cause extreme tiredness and unconsciousness, and worsen symptoms of depression and other conditions, such as anxiety disorders.

Pregnancy and breastfeeding

Consult your doctor or pharmacist before taking any medicine.

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before taking this medicine. You should only use Venlabrain Retard after discussing the potential benefits and risks to the unborn child with your doctor.

Make sure your doctor and/or midwife know you are taking Venlabrain Retard. When similar medicines (called selective serotonin reuptake inhibitors: SSRIs) are taken during pregnancy, there may be an increased risk that the baby will have a serious condition called persistent pulmonary hypertension of the newborn (PPHN), causing the baby to breathe faster and appear blue. These symptoms usually start during the first 24 hours after birth. If this happens to your baby, you should contact your doctor and/or midwife immediately.

If you take Venlabrain Retard in the final stages of pregnancy, you may have a higher risk of heavy vaginal bleeding after giving birth, especially if you have a history of bleeding disorders. Your doctor or midwife should know you are taking Venlabrain Retard so they can advise you.

If you are taking this medicine during pregnancy, your baby may have problems with breathing, as well as other symptoms that may occur when born, such as not feeding properly. If your baby has these symptoms when born and you are concerned, contact your doctor and/or midwife, who will be able to advise you.

Venlabrain Retard passes into breast milk. There is a risk of an effect on the baby, so you should discuss this with your doctor, who will decide whether you should stop breastfeeding or stop taking this medicine.

Driving and using machines

Do not drive or use tools or machines until you know how Venlabrain Retard affects you.

Venlabrain Retard contains lactose. If your doctor has told you that you have an intolerance to some sugars, consult them before taking this medicine.

Symptoms of a possible overdose may include: palpitations, changes in the level of consciousness (ranging from drowsiness to coma), blurred vision, seizures or fits, and vomiting.

If you forget to take Venlabrain Retard

If you miss a dose, take it as soon as you remember. However, if it is already time for your next dose, skip the missed dose and take only a single dose as usual. Do not take a double dose to make up for a forgotten dose. Do not take more than the prescribed daily dose of Venlabrain Retard in one day.

If you stop taking Venlabrain Retard

Do not stop taking your treatment or reduce the dose without the advice of your doctor, even if you feel better. If your doctor thinks you no longer need Venlabrain Retard, they may ask you to reduce the dose gradually before stopping treatment completely. It is known that side effects can occur when people stop using this medicine, especially when it is stopped suddenly or the dose is reduced too quickly.

Some patients may experience symptoms such as suicidal thoughts, aggression, tiredness, dizziness, unsteadiness, headache, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, nervousness, agitation, anxiety, confusion, ringing in the ears, tingling or electric shock-like sensations, weakness, sweating, seizures, or flu-like symptoms, and increased blood pressure (which can cause headache, dizziness, ringing in the ears, sweating, etc.).

Your doctor will advise you on how to gradually stop taking Venlabrain Retard. This may take several weeks or months. In some patients, stopping may need to be done very gradually over several months or longer. If you experience any of these or other symptoms that are troublesome, talk to your doctor for further advice.

If you have any other questions about the use of this medicine, ask your doctor or pharmacist.
