IMPORTANT THINGS YOU SHOULD KNOW ABOUT ViePax

Please read all of this leaflet before you start to take your medicine as it contains important information about ViePax.

ViePax is used to treat depression and social anxiety disorder (also known as social phobia).

ViePax 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 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 or change your dose without the advice of your doctor even if you feel better. If you stop taking ViePax abruptly you may get withdrawal reactions - see in section 3 'If you stop taking ViePax'.

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

-    see in section 2 'Before you take ViePax'.

Taking certain other medicines with ViePax 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'.

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'.

More information on all of these points is provided in the rest of this leaflet. Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.

•    Keep this leaflet. You may need to read it again.

•    If you have any further questions, ask your doctor or pharmacist.

•    This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

1.    WHAT ViePax IS AND WHAT IT IS USED FOR

The name of your medicine is ViePax 37.5 mg Tablets or ViePax 75 mg Tablets (referred to as ViePax throughout this leaflet).

ViePax contains the active substance venlafaxine. ViePax 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. 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 is a treatment for adults with depression. Treating depression 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

Do not take ViePax

•    If you are allergic to venlafaxine or any of the other ingredients of ViePax (section 6 contains a full list).

•    If you are also taking, or have taken within the last 14 days, any medicines known as irreversible monoamine oxidase inhibitors (MAOIs), used to treat depression or Parkinson's disease. Taking an irreversible MAOI together with ViePax, can cause serious or even life-threatening side effects. Also, you must wait at least 7 days after you stop taking ViePax before you take any MAOI (see also the section entitled “Other medicines and ViePax" and the information in that section about “Serotonin syndrome").

Warnings and precautions

If any of the following apply to you, please tell your doctor before taking ViePax:

•    If you use other medicines that, if taken concomitantly with ViePax, could increase the risk of developing serotonin syndrome (see the section “Other medicines and ViePax").

•    If you have eye problems, such as certain kinds 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 you have an abnormal heart rhythm.

•    If you have a history of fits (seizures).

•    If you have a history of low sodium levels in your blood (hyponatraemia).

•    If you have a tendency to develop bruises or a tendency to bleed easily (history of bleeding disorders), or if you are taking other medicines that may increase the risk of bleeding e.g., warfarin (use to prevent blood clots).

•    If your cholesterol levels get higher.

•    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. ViePax 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

If you are depressed and/or anxious, 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 previously had thoughts about killing yourself or harming yourself.

•    If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in young adults (less than 25 years old) 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.

You may find it helpful to tell a relative or close friend that you are depressed or anxious, 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

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.

Diabetes

Your blood glucose levels may be altered due to ViePax. Therefore, the dosage of your diabetes medicines may need to be adjusted.

Children and adolescents

ViePax 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 for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed ViePax 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. Also, the long-term safety effects concerning growth, maturation and cognitive and behavioural development of ViePax in this age group has not yet been demonstrated.

Other medicines and ViePax

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. 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.

Your doctor should decide whether you can take ViePax with other medicines, such as:

•    Monoamine oxidase inhibitors which are used to treat depression or Parkinson's disease must not be taken with ViePax. Tell your doctor if you have taken these medicines within the last 14 days. (MAOIs: see the section “What you need to know before you take ViePax").

•    Products associated with serotonin syndrome: Serotonin syndrome:

A potentially life-threatening condition or Neuroleptic Malignant Syndrome (NMS)-like reactions (see the section “Possible Side Effects"), may occur with venlafaxine treatment, particularly when taken with other medicines. Examples of these medicines include:

•    Triptans (used for migraine)

•    Other medicines to treat depression, for instance SNRI, SSRIs, tricyclics, or medicines containing lithium

•    Medicines containing linezolid, an antibiotic (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 pain-killer), fentanyl, tapentadol, pethidine, or pentazocine (used to treat severe pain)

•    Medicines containing dextromethorphan (used to treat coughing)

•    Medicines containing methadone (used to treat opioid drug addiction or severe pain)

•    Medicines containing methylene blue (used to treat high levels of methaemoglobin in the blood)

•    Products containing St. John's Wort (also called Hypericum perforatum, a natural or herbal remedy used to treat mild depression)

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

•    Antipsychotics (used to treat a disease with symptoms such as hearing, seeing or sensing things which are not there, mistaken beliefs, unusual suspiciousness, unclear reasoning and becoming withdrawn)

Signs and symptoms of serotonin syndrome may include a combination of the following: restlessness, hallucinations, loss of coordination, fast heart beat, 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 heart beat, 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.

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

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 allergy)

The following medicines may also interact with ViePax and should be used with caution. It is especially important to mention to 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 to treat high blood pressure and heart problems)

•    Oral contraceptives

Taking ViePax with food and drink

ViePax should be taken with food (see section 3 “How to take ViePax").

You should avoid alcohol while you are taking ViePax.

risks to your unborn child with your doctor.

Make sure your midwife and/or doctor know you are on ViePax. 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 during pregnancy, other symptoms your baby might have when it is born is not feeding properly, in addition to having trouble breathing. 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 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.

Driving and operating machinery

Venlafaxine can cause impaired judgement, thinking, and movement and coordination as well as problems with vision. If you are affected by any of these you should not drive, operate machinery or take part in any activities where such effects could put you or others at risk.
