IMPORTANT THINGS YOU SHOULD KNOW ABOUT ViePax XL
Please read all of this leaflet before you start to take your medicine as it contains important information about ViePax XL.
ViePax XL is used to treat depression, severe and persistent anxiety known as generalised anxiety disorder (GAD), social anxiety disorder (also known as social phobia) and panic disorder (panic attacks).
ViePax XL is not for use in children and adolescents – see in section 2 'Children and adolescents'.
If you have any concerns about how you feel, or about this medication, it is important that you talk to your doctor – even if you feel anxious or worried about doing so. You may find it helpful to tell a friend or relative that you are depressed or suffering from an anxiety disorder, and that you have been prescribed this medication; it might be useful to show them this leaflet.
ViePax XL may not start to work immediately. Some people taking antidepressants may feel worse before feeling better. Your doctor may ask to see you again in a couple of weeks after you start treatment and then regularly until you start to feel well again. Tell your doctor if you do not start to feel better.
Some people who are depressed may think of harming or killing themselves. If this happens you should see your doctor or go to a hospital straight away – see in section 2 'Thoughts of suicide and worsening of your depression or anxiety disorder'.
If you take too many tablets it is important to seek immediate medical attention, even if you feel well, because of the risk of serious side effects.
Do not stop taking ViePax XL or change your dose without the advice of your doctor even if you feel better. If you stop taking ViePax XL abruptly you may get withdrawal reactions – see in section 3 'If you stop taking ViePax XL'.
If you have heart problems such as fast or irregular heart rate or high blood pressure you should talk to your doctor before taking Viepax XL – see in section 2 'Before you take ViePax XL'.
Taking certain other medicines with ViePax XL may cause problems. You should tell your doctor if you are taking any other medicines – see in section 2 'What you need to know before you take ViePax XL'.
See your doctor without delay if you feel restless and feel like you can't keep still, feel 'high' or very over-excited, have jerky muscle movements which you can't control. See section 4 'Possible side effects' for other important information.
If you are pregnant, or intend to become pregnant, or breast-feeding, you should talk to your doctor – see in section 2 'Pregnancy and breast-feeding'.

1. WHAT ViePax XL IS AND WHAT IT IS USED FOR
The name of your medicine is ViePax XL 75 mg or ViePax XL 150 mg Prolonged-release Tablets (referred to as ViePax XL throughout this leaflet).
ViePax XL contains the active substance venlafaxine.
ViePax XL 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. It is thought that people who are depressed and/or anxious have lower levels of serotonin and noradrenaline in the brain. It is not fully understood how antidepressants work, but they may help by increasing the levels of serotonin and noradrenaline in the brain.
ViePax XL is a treatment for adults with depression. ViePax XL is also a treatment for adults with the following anxiety disorders: generalised anxiety disorder, social anxiety disorder (fear or avoidance of social situations) and panic disorder (panic attacks). Treating depression or anxiety disorders properly is important to help you get better. If it is not treated, your condition may not go away and may become more serious and more difficult to treat.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE ViePax XL
Do not take ViePax XL
Warnings and precautions
Talk to your doctor or pharmacist before taking ViePax XL:
ViePax XL may cause a sensation of restlessness or an inability to sit or stand still during the first few weeks of treatment. You should tell your doctor if this happens to you.
Thoughts of suicide and worsening of your depression or anxiety disorder
If you are depressed and/or have anxiety disorders, you can sometimes have thoughts of harming or killing yourself. These may be increased when you first start taking antidepressants, since these medicines all take time to work, usually about two weeks, but sometimes longer.
You may be more likely to think like this:
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.
You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behaviour.
Dry mouth is reported in 10% of patients treated with venlafaxine. This may increase the risk of tooth decay (caries). Therefore, you should take special care in your dental hygiene.
Your blood glucose levels may be altered due to ViePax XL. Therefore, the dosage of your diabetes medicines may need to be adjusted.
Medicines like ViePax XL (so called SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms have continued after stopping treatment.
Children and adolescents
ViePax XL should normally not be used for children and adolescents under 18 years. Also, you should know that patients under 18 have an increased risk of side effects, such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, oppositional behaviour and anger) when they take this class of medicines. Despite this, your doctor may prescribe ViePax XL for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed ViePax XL for a patient under 18, and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen when patients under 18 are taking ViePax XL. Also, the long-term safety effects concerning growth, maturation and cognitive and behavioural development of ViePax XL in this age group has not yet been demonstrated.
Other medicines and ViePax XL
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Do not start or stop taking any medicines,including those bought without a prescription, natural and herbal remedies, before checking with your doctor or pharmacist.
Signs and symptoms of serotonin syndrome may include a combination of the following:
restlessness, hallucinations, loss of coordination, fast heartbeat, increased body temperature, fast changes in blood pressure, overactive reflexes, diarrhoea, 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, fast heartbeat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).
Tell your doctor immediately, or go to the casualty department at your nearest hospital if you think serotonin syndrome is happening to you.

Examples of these medicines include:
The following medicines may also interact with ViePax XL and should be used with caution. It is especially important to mention to your doctor or pharmacist if you are taking medicines containing:
ViePax XL with food , drink and alcohol
ViePax XL should be taken with food (see section 3 “How to take ViePax XL”).

Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. You should use ViePax XL only after discussing the potential benefits and the potential risks to your unborn child with your doctor.
Make sure your midwife and/or doctor know you are on ViePax XL. When taken during pregnancy, similar drugs (SSRIs) may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your baby you should contact your midwife and/or doctor immediately.
If you are taking ViePax XL during pregnancy, in addition to having trouble breathing, another symptom your baby might have when it is born is not feeding properly. If your baby has these symptoms when it is born and you are concerned, contact your doctor and/or midwife who will be able to advise you.
ViePax XL passes into breast milk. There is a risk of an effect on the baby. Therefore, you should discuss the matter with your doctor, and he/she will decide whether you should stop breast-feeding or stop the therapy with ViePax XL.
