What Venlafaxine is and what it is used for
Venlafaxine contains the active ingredient venlafaxine, which 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.
Venlafaxine is a treatment for adults with depression or to prevent the recurrence of major
depressive episodes. Venlafaxine 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.
What you need to know before you take Venlafaxine
Do not take Venlafaxine:
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 venlafaxine, can cause serious or even life-threatening side effects. Also, you
must wait at least 7 days after you stop taking venlafaxine before you take any MAOI
(see also the sections “Serotinin syndrome” and “Other medicines and Venlafaxine”).
Warnings and precautions
Talk to your doctor or pharmacist before taking Venlafaxine:
if you are taking certain medicines that taken with venlafaxine could increase the risk of
developing a potentia l seri ou s si d e - ef fec t calle d serotonin syndrome (see the section
“Other medicines and venlafaxine”).
if you have eye problems, such as certain kinds of glaucoma (increased pressure in the
eye) or if your optician has told you that you may be at increased risk of developing
if you have a history of high blood pressure or if you have recently had a heart attack .
if you, or someone in your family, have a history of heart or heart rhythm problems.
if you have a history of fits (seizures).
if you have a history of low sodium levels in your blood (hyponatraemia). Also, if you are
elderly, are taking diuretics (water tablets that may cause increased production of urine) or
are dehydrated (e.g. due to severe diarrhoea or being sick).
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 thin the blood and may
increase the risk of bleeding.
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. You may feel aggressive especially during the
early stages of treatment with venlafaxine, if your dose is changed or when you stop
taking.if you have diabetes (this medicine may affect blood sugar levels).
if you are taking any medicine to lose weight.
This medicine may cause an increase in blood pressure or cholesterol levels. Your doctor
may check your blood pressure and cholesterol levels regularly.
If you get a sensation of restlessness or an inability to sit or stand still, which may occur

may be seen in faeces.
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
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 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
Dry mouth is reported in 1 in 10 people taking venlafaxine. This may increase the risk of tooth
decay. Therefore, you should take special care in your dental hygiene.
Children and adolescents under the age of 18
Venlafaxine should normally not be used in children and adolescents under 18 years. Also, you
should know that patients under the age of 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 Venlafaxine for patients under 18 because he/she decides that this is in their best
interests. If your doctor has prescribed Venlafaxine 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 mentioned above develop or worsen when patients under 18 are taking
Venlafaxine. Also, the long-term safety effects concerning growth, maturation, and cognitive
and behavioural development of venlafaxine in this age group have not yet been demonstrated.

other medicines, including medicines obtained without a prescription, natural and herbal

before you take Venlafaxine”).

potential risks to your unborn child with your doctor.

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
