1. What Venlafaxine NORMON is and what it is used for

Venlafaxine NORMON is an antidepressant belonging 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. It is believed that people who are depressed and/or suffer from anxiety have lower levels of serotonin and noradrenaline in the brain. The exact way antidepressants work is not fully understood, but they may help increase the levels of serotonin and noradrenaline in the brain.

Venlafaxine NORMON is a treatment for depression in adults. Properly treating depressive disorders is important to help you feel better. If left untreated, your condition may not improve or may worsen and become more difficult to treat.

2. What you need to know before taking Venlafaxine NORMON

Do not take Venlafaxine NORMON

• If you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6).
• If you are also taking or have taken at any time within the last 14 days any medicine known as an irreversible monoamine oxidase inhibitor (MAOI) used to treat depression or Parkinson's disease. Taking an irreversible MAOI together with other medicines, including Venlafaxine NORMON, may cause serious or even potentially life-threatening adverse effects. In addition, you must wait at least 7 days after stopping Venlafaxine NORMON before taking any irreversible MAOI (see also sections “Serotonin syndrome” and “Use with other medicines”).

Warnings and precautions

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

• If you are using other medicines that, when taken concomitantly with Venlafaxine NORMON, could increase the risk of developing serotonin syndrome (see section “Use with other medicines”).
• 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 a history of seizures (fits).
• If you have a history of low sodium levels in the blood (hyponatremia).
• If you tend to develop bruises easily or have a tendency to bleed easily (history of bleeding disorders), or if you are taking other medicines that may increase the risk of bleeding, or if you are pregnant (see “Pregnancy and breastfeeding”).
• If your cholesterol levels increase.
• 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 behavior.

Venlafaxine NORMON may cause a feeling of restlessness or an inability to sit or stand still. You should consult your doctor if this occurs.

Some medicines in the group to which Venlafaxine NORMON belongs (called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after discontinuation of treatment.

If any of these conditions apply to you, consult your doctor before taking Venlafaxine NORMON.

Do not drink alcohol during treatment with Venlafaxine NORMON, as it may cause extreme tiredness 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 suffer from anxiety disorders, you may occasionally have thought about self-harm or suicide. These thoughts may increase when you first start taking antidepressants, as these medicines take time to work—usually about two weeks, but sometimes longer.

You may be more likely to have such thoughts:

• If you have previously had suicidal thoughts or thoughts of self-harm.
• If you are a young adult. Clinical trial data have shown an increased risk of suicidal behavior in young adults (under 25 years of age) with psychiatric conditions treated with antidepressants.

If you have thoughts of self-harm or suicide at any time, contact your doctor or go directly to a hospital.

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 could ask them whether they think your depression or anxiety is getting worse, or if they are concerned about changes in your behavior.

Dry mouth

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

Use in children and adolescents under 18 years of age

Venlafaxine NORMON must not be used in children and adolescents under 18 years of age. In addition, you should know that patients under 18 years of age have an increased risk of adverse effects such as suicide attempts, suicidal thoughts, and there have been increased reports of hostility (predominantly aggression, oppositional behavior, and anger) when taking this group of medicines. Despite this, your doctor may prescribe Venlafaxine NORMON to patients under 18 years of age if they decide it is the most appropriate for the patient. If your doctor has prescribed Venlafaxine NORMON to a patient under 18 years of age and you wish to discuss this decision, speak to your doctor. You must inform your doctor if any of the symptoms listed above develop or worsen when these patients under 18 years of age are taking Venlafaxine NORMON. In addition, the long-term effects of venlafaxine on growth, puberty, and development in this age group have not been established.

Taking Venlafaxine NORMON with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicine. Your doctor must decide whether you can take Venlafaxine NORMON with other medicines.

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

• Monoamine oxidase inhibitors (MAOIs): See section “Before taking Venlafaxine NORMON”

• Serotonin syndrome: Serotonin syndrome, a potentially life-threatening condition (see section “Possible side effects”), may occur with venlafaxine treatment, particularly when taken with other medicines. Examples of such medicines include:

• triptans (used for migraine)

• medicines to treat depression, for example, SNRIs, SSRIs, tricyclic antidepressants, or medicines containing lithium

• 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 tramadol (a painkiller)

• products containing St. John’s wort (also known as “Hypericum perforatum”, a natural or herbal remedy used to treat mild depression)

• products containing tryptophan (used for problems such as sleep and depression)

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, hyperactive reflexes, diarrhea, nausea, vomiting, and coma. Seek immediate medical attention if you think you are experiencing serotonin syndrome.

The following medicines may also interact with Venlafaxine NORMON 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 (for treating psychiatric conditions)
• metoprolol (a beta-blocker used to treat high blood pressure and heart problems)

Taking Venlafaxine NORMON with food, drinks, and alcohol

Venlafaxine NORMON should be taken with food (see section 3 “HOW TO TAKE VENLAFAXINE NORMON”).

Do not drink alcohol during treatment with Venlafaxine NORMON. Taking it together with alcohol may cause extreme tiredness and unconsciousness, and may worsen symptoms 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 become pregnant, consult your doctor or pharmacist before using this medicine. You should only use Venlafaxine NORMON after discussing the possible benefits and possible risks to the unborn child with your doctor.

If you are taking Venlafaxine NORMON during pregnancy, inform your midwife and/or doctor, as your baby may experience some symptoms after birth. These symptoms usually begin within the first 24 hours after birth. These include feeding difficulties and breathing problems. If your baby has these symptoms at birth and you are concerned, contact your doctor and/or midwife, who can advise you.

If you are taking Venlafaxine NORMON during pregnancy, inform your midwife and/or doctor. When similar medicines (called serotonin reuptake inhibitor antidepressants: SSRIs) are taken during pregnancy, there may be an increased risk of the baby developing a serious condition 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 birth. If this occurs in your case, you must contact a doctor and/or midwife immediately.

If you take Venlafaxine NORMON 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 be aware that you are taking Venlafaxine NORMON so they can advise you.

Venlafaxine NORMON 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 you should stop breastfeeding or stop treatment with Venlafaxine NORMON.

Driving and using machines

During treatment with Venlafaxine NORMON, you may feel drowsy or dizzy. Do not drive or operate tools or machinery until you know how Venlafaxine NORMON affects you.
