Sunveniz 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. Sunveniz XL is a medicine to treat adults with depression. Sunveniz XL is also used to treat 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.
e Sunveniz XL
Do not take Sunveniz XL 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 any time 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 other medicines, including Sunveniz XL, can cause serious or even life-threatening side effects. Also, you must wait at least 7 days after you stop taking Sunveniz XL before you take any MAOI (see also "Other medicines and Sunveniz XL" and the information in the section about "Serotonin Syndrome"). Warnings and precautions If any of the following apply to you, please tell your doctor or pharmacist before taking Sunveniz XL if you use other medicines that taken together with Sunveniz XL could increase the risk of developing serotonin syndrome (see the section " Other medicines and Sunveniz XL") 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 V027

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 (used to prevent blood clots), or if you are pregnant (see 'Pregnancy') if you have a history of, or if someone in your family has had, mania or bipolar disorder (feeling overexcited or euphoric) if you have a history of aggressive behaviour.
Sunveniz 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. Do not drink alcohol while being treated with Venlafaxine SUN as it can lead to extreme tiredness and unconsciousness. Concomitant use with alcohol and/or certain medicines can make your symptoms of depression and other conditions, such as anxiety disorders worse. 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. These thought may also occur when your dose is decreased or during discontinuation of treatment with Sunveniz XL. You may be more likely to think like this: If you have previously had thoughts about killing or harming yourself. If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in 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 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 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 Sunveniz XL. Therefore, the dosage of your diabetes medicines may need to be adjusted. Sexual problems Medicines like Sunveniz 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 Sunveniz 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 this medicine for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed this medicine 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
V027

symptoms listed above develop or worsen when patients under 18 are taking Sunveniz XL. Also, the longterm safety concerning growth, maturation and cognitive and behavioural development of this medicine in this age group has not yet been demonstrated. Other medicines and Sunveniz XL Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Your doctor should decide whether you can take Sunveniz XL with 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. –

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:
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.
