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. Do not pass it on to others. It may harm them, even if

If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please
tell your doctor or pharmacist.

Further information
The name of your medicine is VENLADEX 37.5 mg Tablets or VENLADEX 75 mg Tablets (referred to
as VENLADEX throughout this leaflet).
VENLADEX 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.
VENLADEX 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.
Do not take VENLADEX

If you are allergic to venlafaxine or any of the other ingredients of VENLADEX (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, can cause serious or even life-threatening side
effects. Also, you must wait at least 7 days after you stop taking VENLADEX before you take any
MAOI (see also the section entitled “Taking other medicines” and the information in that section
about “Serotonin syndrome”).
Take special care with VENLADEX
If any of the following apply to you, please tell your doctor before taking VENLADEX:

If you use other medicines that, if taken concomitantly with VENLADEX, 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 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 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.
Your blood glucose levels may be altered due to VENLADEX. Therefore, the dosage of your diabetes
medicines may need to be adjusted.

Use in children and adolescents under 18 years of age
VENLADEX 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 for patients under 18 because
he/she decides that this is in their best interests. If your doctor has prescribed VENLADEX 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.
Also, the long-term safety effects concerning growth, maturation and cognitive and behavioural
development of VENLADEX 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.
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 VENLADEX with other medicines, such as:

Monoamine oxidase inhibitors which are used to treat depression or Parkinson’s disease must not
be taken with VENLADEX. Tell your doctor if you have taken these medicines within the last 14
days. (MAOIs: see the section “Before you take VENLADEX”).
Products associated with serotonin syndrome:
Serotonin syndrome:

(see the section “Possible Side Effects, Nervous system disorders”), 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
• 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)

• 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

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.
The following medicines may also interact with VENLADEX and should be used with caution. It is
especially important to mention to your doctor or pharmacist if you are taking medicines containing:
