1. What Venlafaxine Retard Normogen is and what it is used for

Venlafaxine Retard Normogen contains the active substance venlafaxine.

Venlafaxine is an antidepressant which belongs to a group of medicines known as serotonin and norepinephrine reuptake inhibitors (SNRIs). This group of medicines is used to treat depression and other conditions such as anxiety disorders. The way antidepressants work is not fully understood, but they may help increase levels of serotonin and norepinephrine in the brain.

Venlafaxine is a treatment for depression in adults. It is also a treatment for the following anxiety disorders in adults: generalized anxiety disorder, social anxiety disorder (fear or avoidance of social situations), and panic disorder (panic attacks). Properly treating depressive and anxiety disorders is important to help you feel better. If left untreated, your condition may not go away or may worsen and become more difficult to treat.

2. What you need to know before taking Venlafaxine Retard Normogen

Do not take Venlafaxine Retard Normogen

• If you are allergic to venlafaxine or to 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, a medicine known as an irreversible monoamine oxidase inhibitor (MAOI) used to treat depression or Parkinson’s disease. Taking an irreversible MAOI together with venlafaxine may cause serious, potentially life-threatening side effects. In addition, you must wait at least 7 days after stopping venlafaxine before taking any MAOI (see also section “Other medicines and Venlafaxine Retard Normogen” and the information in that section about “Serotonin Syndrome”).

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Venlafaxine Retard Normogen:

• If you are using other medicines that, when taken together with venlafaxine, could increase the risk of developing serotonin syndrome (see section “Other medicines and Venlafaxine Retard Normogen”).
• 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 a history of heart problems.
• If you have been told that your heart rhythm is abnormal.
• If you have a history of seizures (fits).
• If you have a history of low sodium levels in the blood (hyponatremia).
• If you have a history of bleeding disorders (tendency to bruise easily or tendency to bleed easily), or if you are taking other medicines that may increase the risk of bleeding, e.g., warfarin (used to prevent blood clots), or if you are pregnant (see section Pregnancy, breastfeeding and fertility).
• If you have a history of, or if someone in your family has had, mania or bipolar disorder (feeling over-excited or euphoric).
• If you have a history of aggressive behaviour.

Venlafaxine 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 during treatment with Venlafaxine Retard Normogen, as it may cause extreme drowsiness and unconsciousness. Taking it together with certain medicines and/or alcohol may worsen symptoms of depression and other conditions, such as anxiety disorders.

Suicidal thoughts and worsening of your depression or anxiety disorder

If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or of suicide. These thoughts may increase when you first start taking antidepressants, as all these medicines take time to work, usually about two weeks, although sometimes longer. These thoughts may also occur when your dose is reduced or during discontinuation of treatment with venlafaxine.

This is more likely to happen if:

• You have previously had thoughts of suicide or of harming yourself.
• You are a young adult. Clinical trial data have shown an increased risk of suicidal behaviour in young adults (under 25 years of age) with psychiatric illnesses who were treated with antidepressants.

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

You may find it helpful to tell a close family member or friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You may also ask them to let you know if they think your depression or anxiety is getting worse, or if they are concerned about changes in your behaviour.

Dry mouth

Dry mouth has been reported in 10% of patients treated with venlafaxine. This may increase the risk of tooth decay (caries). Therefore, you should take care of your dental hygiene.

Diabetes

Your blood glucose levels may be altered by venlafaxine. Therefore, the doses of your diabetes medications may need to be adjusted.

Sexual problems

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

Children and adolescents

Venlafaxine should not normally be used to treat children and adolescents under 18 years of age. In addition, you should know that in patients under 18 years of age, there is an increased risk of adverse effects such as suicide attempts, suicidal thoughts, and hostility (predominantly aggression, confrontational behaviour, and irritability) when taking this type of medicine. Nevertheless, your doctor may prescribe this medicine to patients under 18 years of age if they decide it is best for the patient. If your doctor has prescribed this medicine to a patient under 18 years of age and you wish to discuss this decision, please consult your doctor again. You must inform your doctor if any of the symptoms listed above develop or worsen while these patients under 18 years of age are taking venlafaxine.

In addition, long-term safety with regard to growth, maturation, and cognitive and behavioural development has not been established.

Other medicines and Venlafaxine Retard Normogen

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

Your doctor must decide whether you can take venlafaxine with other medicines.

Do not start or stop taking any medicine, including those available without a prescription, herbal remedies, or plant-based products, without first checking with your doctor or pharmacist.

• Monoamine oxidase inhibitors (MAOIs) used to treat depression or Parkinson’s disease must not be taken with venlafaxine. Tell your doctor if you have taken any of these medicines in the last 14 days. (MAOIs: see section “What you need to know before taking Venlafaxine Retard Normogen”).

• Serotonin syndrome:

A potentially life-threatening condition, or reactions resembling Neuroleptic Malignant Syndrome (NMS) (see section “Possible Side Effects”), may occur during treatment with venlafaxine, particularly when taken with other medicines.

Examples of these medicines include:

• Triptans (used for migraine).
• Other medicines to treat depression, for example, SNRIs, SSRIs, tricyclic antidepressants, or 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, an MAOI (used to treat depression).
• Medicines containing sibutramine (used for weight loss).
• Medicines containing opioids (e.g., buprenorphine, tramadol, fentanyl, tapentadol, meperidine, or pentazocine), used to treat severe pain.
• Medicines containing dextromethorphan (used to treat cough).
• Medicines containing methadone (used for opioid addiction treatment or for treatment of severe pain).
• Medicines containing methylene blue (used to treat elevated levels of methemoglobin in blood).
• Herbal products containing St. John’s wort (also known as “Hypericum perforatum”, a herbal or plant-based remedy used to treat mild depression).
• Products containing tryptophan (used for problems such as sleep and depression).
• Antipsychotics (used to treat illnesses with symptoms such as hearing, seeing, or feeling things that are not there, false beliefs, unusual suspicion, unclear thinking, and tendency to withdraw).

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, diarrhoea, coma, nausea, vomiting.

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

Contact your doctor immediately or go to the nearest hospital emergency department if you think you are experiencing serotonin syndrome.

Tell your doctor if you are taking medicines that may affect your heart rhythm.

Some examples of these medicines include:

• Antiarrhythmics such as quinidine, amiodarone, sotalol, or dofetilide (used to treat abnormal heart rhythm).
• 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 venlafaxine and should be used with caution. It is especially important to tell your doctor or pharmacist if you are taking medicines containing:

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

Taking Venlafaxine Retard Normogen with food, drinks, and alcohol

Venlafaxine should be taken with food (see section 3 “How to take Venlafaxine Retard Normogen”).

Do not drink alcohol during treatment with Venlafaxine Retard Normogen. Taking it together with alcohol may cause extreme drowsiness and unconsciousness, and may worsen symptoms of depression and other conditions, such as anxiety disorders.

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine. You should only take venlafaxine after discussing with your doctor the possible benefits and possible risks to the unborn child.

Make sure your midwife and/or doctor knows that you are taking venlafaxine. Medicines similar to venlafaxine (SSRIs) taken during pregnancy may increase the risk of a serious condition in newborns called persistent pulmonary hypertension of the newborn (PPHN), causing the baby to breathe faster and appear blue. These symptoms usually begin within the first 24 hours after the baby’s birth. If this happens to your baby, contact your midwife and/or doctor immediately.

If you take venlafaxine in the late stages of pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should know you are taking venlafaxine so they can advise you.

If you take this medicine during pregnancy, in addition to breathing problems, another symptom your baby may have at birth is feeding difficulties. If your baby has these symptoms at birth and you are concerned, contact your doctor and/or midwife, who can advise you.

Venlafaxine passes into breast milk. There is a risk of effects on the baby. Therefore, you should discuss this with your doctor, who will decide whether to stop breastfeeding or to stop treatment with this medicine.

Driving and using machines

Do not drive or operate tools or machinery until you know how this medicine affects you.

Venlafaxine Retard Normogen contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per capsule; essentially “sodium-free”.

3. How to take Venlafaxine Retard Normogen

Follow exactly the instructions for use of this medicine as given by your doctor. If in doubt, consult your doctor or pharmacist again.

The usual recommended starting dose for the treatment of depression, generalized anxiety disorder, and social anxiety disorder is 75 mg per day. Your doctor may gradually increase the dose, and if necessary, further increase it up to a maximum of 375 mg per day for depression. If you are being treated for panic disorder, your doctor will start with a lower dose (37.5 mg) and then gradually increase the dose. The maximum dose for generalized anxiety disorder, social anxiety disorder, and panic disorder is 225 mg/day.

Take venlafaxine at approximately the same time each day, either in the morning or in the evening. The capsules must be swallowed whole with liquid and must not be opened, crushed, chewed, or dissolved.

Venlafaxine should be taken with food.

If you have liver or kidney problems, talk to your doctor, as your dose of this medicine may need to be adjusted.

Do not stop taking this medicine without consulting your doctor (see section “If you stop taking Venlafaxine Retard Normogen”).

If you take more Venlafaxine Retard Normogen than you should

In case of overdose or accidental ingestion, contact your doctor, pharmacist, or call the Toxicology Information Service at telephone number 91 562 04 20, indicating the medicine and the amount ingested.

Overdose can be life-threatening, especially when taken simultaneously with certain medicines and/or alcohol (see “Other medicines and Venlafaxine Retard Normogen”).

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

If you forget to take Venlafaxine Retard Normogen

If you have missed a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take only your next dose at the usual time. Do not take a double dose to make up for a missed dose. Do not take more than the daily amount of venlafaxine prescribed for you in one day.

If you stop taking Venlafaxine Retard Normogen

Do not stop or reduce your treatment without consulting your doctor, even if you feel better. If your doctor considers that you no longer need venlafaxine, they may ask you to gradually reduce the dose before stopping treatment completely. Adverse effects are known to 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, fatigue, dizziness, unsteadiness, headache, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, nervousness, agitation, confusion, tinnitus, tingling sensations, or, rarely, electric shock-like sensations, weakness, sweating, seizures, flu-like symptoms, visual disturbances, and increased blood pressure (which may cause headache, dizziness, tinnitus, sweating, etc.).

Your doctor will advise you on how to gradually discontinue treatment with venlafaxine. This may take several weeks or months. In some patients, discontinuation may need to be very gradual over months or longer. If you experience any of these or other bothersome symptoms, consult your doctor for advice.

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

4. Possible adverse effects

Like all medicines, this medicine can cause adverse effects, although not everyone experiences them.

If any of the following effects occur, stop taking venlafaxine and contact your doctor immediately or go to the nearest hospital emergency department:

Uncommon (may affect up to 1 in 100 people)

• Swelling of the face, mouth, tongue, throat, hands, or feet and/or swollen, itchy rash, difficulty swallowing or breathing.

Rare (may affect up to 1 in 1,000 people)

• Chest tightness, noisy breathing, difficulty swallowing or breathing.

In its most severe form, serotonin syndrome may resemble neuroleptic malignant syndrome (NMS). Signs and symptoms of NMS may include a combination of fever, rapid heartbeat, sweating, severe muscle stiffness, confusion, and increased muscle enzymes (detected by a blood test).
• Signs of infection, such as increased temperature, chills, shivering, headache, sweating, or flu-like symptoms. This may be due to a blood disorder that can lead to an increased risk of infection.
• Severe rash, which may progress to the formation of severe blisters and skin peeling.
• Unexplained muscle pain, discomfort, or weakness. This may be a sign of rhabdomyolysis.

Frequency not known (cannot be estimated from available data)

• Signs and symptoms of a condition called "stress cardiomyopathy" (also known as Takotsubo cardiomyopathy), which may include chest pain, difficulty breathing, dizziness, fainting, or irregular heartbeats.

• Prolonged bleeding—if you are cut or sustain a wound, it may take slightly longer than normal for the bleeding to stop.

Do not be alarmed if you notice white balls or small granules in your faeces after taking this medicine. Inside the capsules of Venlafaxine Retard Normogen there are spheroids (small white balls) containing the active substance (venlafaxine). These spheroids are released from the capsule in the stomach. As they pass through the stomach and intestines, venlafaxine is slowly released. The "shell" of the spheroid does not dissolve and is excreted in the faeces. Therefore, even if you see spheroids in your faeces, the dose of the medicine has been absorbed.

Other possible adverse effects

Very common (may affect more than 1 in 10 people)

Venlafaxine may sometimes cause unwanted effects that you may not be aware of, such as increases in blood pressure or an abnormal heartbeat; mild changes in blood levels of liver enzymes, sodium, or cholesterol. Less frequently, venlafaxine may reduce the function of blood platelets, leading to an increased risk of bruising or bleeding. Therefore, your doctor may wish to carry out occasional blood tests, especially if you have been taking venlafaxine for a long time.
