6. Further information
Alventa 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.
Alventa XL is a treatment for adults with depression. Alventa XL is also a treatment for adults with the following anxiety
disorder: social anxiety disorder (fear or avoidance of social situations). 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.
Do not take Alventa XL
• If you are allergic to venlafaxine or any of the other ingredients of Alventa XL.
• 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 Alventa XL, can cause serious or even life-threatening side effects. Also, you must wait at least 7 days after you stop
taking Alventa XL before you take any MAOI (see also the sections “Serotonin syndrome” and “Taking other medicines”).
Take special care with Alventa XL
• If you use other medicines that taken concomitantly with Alventa XL could increase the risk of developing serotonin syndrome
(see the section “Taking other medicines”).
• 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 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.
• 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.
• If you have diabetes.
Alventa XL may cause a sensation of restlessness or an inability to sit or stand still. You should tell your doctor if this happens
to you.
If any of these conditions apply to you, please talk with your doctor before taking Alventa XL.
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 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 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 caries. Therefore, you should take
special care in your dental hygiene.
Use in children and adolescents under 18 years of age
Alventa 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 Alventa XL for
patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed Alventa 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 Alventa XL. Also, the long-term safety effects concerning
growth, maturation and cognitive and behavioural development of Alventa XL in this age group has not yet been demonstrated.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained
without a prescription.
Your doctor should decide whether you can take Alventa 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.
• Monoamine oxidase inhibitors (MAOIs: see the section “Before you take Alventa XL”).
• Serotonin syndrome: Serotonin syndrome, a potentially life-threatening condition (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)
• 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)

coordination, fast heart beat, increased body temperature, fast changes in blood pressure, overactive reflexes, diarrhoea, coma,
nausea, vomiting. Get medical care right away if you think serotonin syndrome is happening to you.

the potential benefits and the potential risks to your unborn child with your doctor.
Make sure your midwife and/or doctor knows you are on Alventa 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 Alventa XL during pregnancy, let your midwife and/or doctor know, as your baby might have some symptoms
when it is born. These symptoms usually begin during the first 24 hours after the baby is born. They include not feeding properly
and trouble with 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.
