1. WHAT VENLADEX XL IS AND WHAT IT IS
The name of your medicine is VENLADEX XL 75
mg or VENLADEX XL 150 mg Prolonged-Release
Tablets (referred to as VENLADEX XL throughout
VENLADEX XL contains the active substance
VENLADEX 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.
VENLADEX XL is a treatment for adults with
depression. VENLADEX 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 VENLADEX XL
Do not take VENLADEX XL
• If you are allergic to venlafaxine or any of the other
ingredients of VENLADEX XL (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 VENLADEX XL,
can cause serious or even life-threatening side
effects. Also, you must wait at least 7 days after
you stop taking VENLADEX XL before you take
any MAOI (see also the section entitled “Other
medicines and Venladex XL” 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 VENLADEX XL:
• If you use other medicines that, if taken
concomitantly with VENLADEX XL, could increase
the risk of developing serotonin syndrome (see
the section “Other medicines and Venladex 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.
• If you have been told you have an abnormal heart
• If you have a history of fits (seizures).
• If you have a history of low sodium levels in your
• 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.
VENLADEX 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 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
If you have thoughts of harming or killing yourself
at any time, contact your doctor or go to a hospital
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
VENLADEX XL. Therefore, the dosage of your
diabetes medicines may need to be adjusted.
Children and adolescents
VENLADEX 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 VENLADEX
XL for patients under 18 because he/she decides
that this is in their best interests. If your doctor has
prescribed VENLADEX 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 VENLADEX
XL. Also, the long-term safety effects concerning
growth, maturation and cognitive and behavioural
development of VENLADEX XL in this age group
has not yet been demonstrated.

hours after the baby is born. If this happens to your
