Full Consumer Medicine Information (CMI)
This leaflet provides important information about using ENLAFAX-XR. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about taking ENLAFAX-XR.
Where to find information in this leaflet:
1. Why am I taking ENLAFAX-XR?
ENLAFAX-XR contains the active ingredient
venlafaxine hydrochloride
. It belongs to a class of medications for depression and anxiety, called Serotonin-Noradrenaline
Reuptake Inhibitors (SNRIs).
Serotonin and noradrenaline are chemical messengers that allow certain nerves in the
brain to work. ENLAFAX-XR capsules increase the level of these two messengers. Experts
think this is how it helps to restore your feeling of wellness.
There is no evidence that ENLAFAX-XR is addictive.
ENLAFAX-XR is used in the treatment and prevention of relapse of depression and in
the treatment of social phobia (social anxiety disorder).
Depression is longer lasting or more severe than the 'low moods' that everyone has
from time to time. It is thought to be caused by a chemical imbalance in parts of
the brain. This imbalance affects your whole body and can cause emotional and physical
symptoms such as feeling low in spirit, lose interest in usual activities, be unable
to enjoy life, have poor appetite or over eat, have disturbed sleep, often waking
up early, loss of sex drive, low energy and feel guilty over nothing.
Social phobia is a fear of being embarrassed, judged or evaluated negatively in social
situations, which can result in substantial impairment in the person's social emotional,
interpersonal and occupational life.
Depression and anxiety are treatable illnesses. Anxiety or tension associated with
the normal stress of everyday life usually does not require treatment with medicines.
Ask your doctor if you have any questions about why ENLAFAX-XR has been prescribed
for you.
Your doctor may have prescribed it for another reason.
Use in Children
Do not give ENLAFAX-XR to children or adolescents under 18 years of age.
The safety and effectiveness of ENLAFAX-XR in this age group have not been established.
2. What should I know before I take ENLAFAX-XR?
Warnings
Do not take ENLAFAX-XR if:
you are taking other medications for depression known as monoamine oxidase inhibitors,
even if you have stopped taking them now, but have taken them within the last 14 days.
you are allergic to venlafaxine, or any of the ingredients listed at the end of this
leaflet.
Symptoms of an allergic reaction may include:
rash, itching or hives on the skin
swelling of the face, lips, tongue, throat or other parts of the body
shortness of breath, wheezing or troubled breathing; difficulty swallowing.
Always check the ingredients to make sure you can use this medicine.
the expiry date printed on the pack has passed or if the packaging is torn or shows
signs of tampering.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Check with your doctor or pharmacist if you:
have any other medical conditions
take any medicines for any other condition
have allergies to any other medicines, foods, preservatives or dyes.
During treatment, you may be at risk of developing certain side effects. It is important
you understand these risks and how to monitor for them. See additional information
under Section
6. Are there any side effects?
Pregnancy and breastfeeding
Check with your doctor or pharmacist if you are pregnant or intend to become pregnant.
ENLAFAX-XR is not recommended for use during pregnancy. Your doctor will discuss the
risks and benefits of taking ENLAFAX-XR if you are pregnant. One of these risks is
that newborn babies, whose mothers have been taking ENLAFAX-XR in the last few months
of pregnancy, may experience problems soon after delivery, including breathing difficulties,
seizures and lack of oxygen in their blood.
If you take ENLAFAX-XR or similar anti-depressants mid to late in your pregnancy,
you may develop a condition known as "pre-eclampsia", which is characterised by persistent
high blood pressure during or after pregnancy. Symptoms of pre-eclampsia can include
headaches, abdominal pain, shortness of breath or burning around the sternum, nausea
and vomiting, confusion, heightened state of anxiety, and/or visual disturbances such
as oversensitivity to light, blurred vision, or seeing flashing spots or auras.
If you take ENLAFAX-XR or similar antidepressants in the last month of your pregnancy,
you may experience heavy vaginal bleeding shortly after birth (postpartum haemorrhage).
Continuing treatment with ENLAFAX-XR or similar antidepressants during pregnancy should
be strictly as directed by your doctor. Symptoms of a relapse may occur if treatment
is discontinued, even if major depression was previously under control.
Talk to your doctor or pharmacist if you are breastfeeding or intend to breastfeed.
ENLAFAX-XR passes into breast milk and there is a possibility that the breast-fed
baby may be affected. For this reason, the use of ENLAFAX-XR is not recommended in
breast-feeding women.
Tell your doctor if you have or have had any of the following medical conditions:
a history of fits (seizures or convulsions)
a personal history or family history of bipolar disorder
a history of aggression
a history of restlessness or difficulty sitting still
diabetes
blood pressure problems
glaucoma (increased pressure in the eye)
a tendency to bleed more than normal or you are taking medicines to prevent blood
clots
raised cholesterol levels or you are taking medicines to lower cholesterol
problems with your kidneys or liver
problems with your heart, especially conditions causing irregular heartbeats.
Your doctor may wish to do some heart tests such as an electrocardiogram (ECG) or
blood tests during treatment with ENLAFAX-XR.
Tell your doctor if you plan to have surgery.
If you have not told your doctor about any of the above, tell them before you start
taking ENLAFAX-XR.
3. What if I am taking other medicines?
Tell your doctor or pharmacist if you take any other medicines, including:
all prescription medicines
all medicines, vitamins, herbal supplements or natural therapies you buy without a
prescription from a pharmacy, supermarket, naturopath or health food shop such as
St John's Wort or tryptophan supplements.
Do not start to take any other medicine while you are taking ENLAFAX-XR, unless it
is prescribed or approved by your doctor.
Some medicines may interfere with ENLAFAX-XR, or ENLAFAX-XR may interfere with these
medicines. These include:
Medications for depression known as monoamine oxidase inhibitors (such as moclobemide,
linezolid, phenelzine and tranylcypromine), even if you have stopped taking them now,
but have taken them within the last 14 days. Your doctor or pharmacist can tell you
what to do if you are taking any of these medicines
Allow at least 7 days after stopping ENLAFAX-XR before starting a MAOI.
Taking this medicine with a MAOI, or within 7 days of taking a MAOI, may cause a serious
reaction with a sudden increase in body temperature, extremely high blood pressure
and severe convulsions.
The appropriate washout period is needed to prevent severe adverse reactions.
any other medications for depression, anxiety, obsessive-compulsive disorder or premenstrual
dysphoric disorder, including St John's Wort
medicines for treating mental disorders such as haloperidol, risperidone, lithium
or clozapine
tramadol, fentanyl, tapentadol, pethidine, methadone and pentazocine used to treat
strong pain
amphetamines used to treat attention deficit hyperactivity disorder or ADHD
cimetidine for reflux and stomach ulcers
triptans used to treat migraine
amiodarone or quinidine used to treat irregular heartbeats.
Your doctor may do some tests such as an electrocardiogram (ECG) or blood tests if
you are taking either of these medicines whilst taking ENLAFAX-XR:
metoprolol for high blood pressure or angina
medicines used to prevent blood clotting such as platelet inhibitors and anti-coagulants
e.g., warfarin
indinavir for viral infections
medicines for weight loss
antibiotics such as erythromycin and linezolid for bacterial infections
ketoconazole or fluconazole for fungal infections.
These medicines may be affected by ENLAFAX-XR or may affect how well it works. You
may need to use different amounts of your medicine, or you may need to take different
medicines. Your doctor will advise you.
Your doctor and pharmacist have more information on medicines to be careful with or
avoid while taking ENLAFAX-XR.
4. How do I take ENLAFAX-XR?
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist
for help.
How much to take
Your doctor will tell you how many capsules you need to take each day. This may depend
on your age, your condition and whether or not you are taking any other medicines.
The usual starting dose is 75mg taken once daily. After 2 weeks, your doctor may increase
your dose.
Do not change dose unless your doctor tells you to.
If you have kidney or liver problems, you may need a lower dose of ENLAFAX-XR.
If you have heart problems your doctor may first do some blood tests or heart tests
such as an electrocardiogram (ECG) before increasing your dose of ENLAFAX-XR.
How to take ENLAFAX-XR
Swallow the capsules whole with a glass of water or other non-alcoholic liquid.
DO NOT DIVIDE, CRUSH, CHEW OR DISSOLVE THE CAPSULES IN WATER.
Taking divided, chewed or crushed ENLAFAX-XR capsules, in theory, could lead to the
rapid release and absorption of venlafaxine.
When to take ENLAFAX-XR
Take ENLAFAX-XR once daily with food, at approximately the same time each day.
This could be either in the morning or in the evening.
Taking it at the same time each day will have the best effect. It will also help you
remember when to take it.
How long to take ENLAFAX-XR
Continue taking your medicine for as long as your doctor tells you.
The length of treatment will depend on how quickly your symptoms improve. Most antidepressants
take time to work, so don't be discouraged if you don't feel better right away. Some
of your symptoms may improve in 1 or 2 weeks but it can take up to another few weeks
to feel any real improvement.
Even when you feel well, it is important to keep taking your medicine. You will usually
have to take ENLAFAX-XR for several months or even longer to make sure the benefits
will last. Discuss this with your doctor and don't stop taking ENLAFAX-XR until gaining
your doctor's agreement.
If you forget to take ENLAFAX-XR
ENLAFAX-XR should be taken regularly at the same time each day.
If it is less than 12 hours until your next dose, skip the dose you missed and then
take your next dose when you are meant to. Otherwise, take it as soon as you remember,
and then go back to taking as you would normally.
Do not take a double dose to make up for the dose you missed.
This may increase the chance of you getting an unwanted side effect.
Contact your doctor if you have missed more than two doses in a row.
Always finish the capsules you are taking in the current pack before you start a new
pack.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some
hints.
If you take too much ENLAFAX-XR
If you think that you or anyone else may have taken too much ENLAFAX-XR, urgent medical
attention may be needed.
You should immediately:
phone the Poisons Information Centre
(Australia telephone 13 11 26) for advice, or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
If you take too many ENLAFAX-XR capsules you may:
feel sleepy
vomit
have an increased heart rate or changes in heart rhythm
have a seizure (fits)
have breathing difficulties
become unconscious
have dilated pupils.
Keep the telephone number for these places handy whilst taking any medications.
5. What should I know while taking ENLAFAX-XR?
Things you should do
Visit your doctor regularly for a check up so that your progress can be checked.
Your doctor may do some tests (such as an electrocardiogram (ECG) or blood tests)
from time to time to make sure the medicine is working and to prevent unwanted side
effects.
Always discuss any questions you have about ENLAFAX-XR capsules with your doctor.
If you are going to have surgery, tell your doctor that you are taking this medicine.
Some agents used to assist your doctor during surgery may interact with ENLAFAX-XR
leading to unwanted side effects.
If you are about to have any urine tests, tell your doctor that you are taking this
medicine.
ENLAFAX-XR may interfere with the results of some tests.
Take ENLAFAX-XR capsules as your doctor has prescribed.
Keep enough ENLAFAX-XR capsules to last weekends and holidays.
ENLAFAX-XR helps to control your condition, but does not cure it. It is important
to keep taking your medicine even if you feel well.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking
this medicine.
Watch carefully for signs that your depression or anxiety is getting worse, especially
in the first few weeks of treatment, or if your dose has changed.
Sometimes people with depression can experience a worsening of their depressive symptoms.
This can happen even when taking an antidepressant.
Information from clinical trials has suggested that children, adolescents and young
adults (18-24 years), particularly those with depression, may be at increased risk
of suicidal behaviour (including suicide attempts) when treated with ENLAFAX-XR, especially
during initial treatment.
Call your doctor straight away if you experience:
anxiety or agitation
panic attacks
difficulty sleeping
irritability
aggressiveness
hostility or impulsiveness
restlessness
overactivity or uninhibited behaviour
other unusual changes in behaviour
thoughts of suicide
tremor, sweating, fast heart rate
muscle rigidity.
Tell your doctor immediately if you experience any of the above symptoms, especially
if they are severe, you have not had these symptoms before or they happen very suddenly.
Symptoms of serotonin syndrome may include mental status changes (e.g. agitation,
confusion, hallucinations, and coma), autonomic instability (e.g. excessive sweating,
fast heart rate, and increased body temperature), neuromuscular aberrations (e.g.
overactive reflexes, incoordination, tremor) and/or gastrointestinal symptoms (e.g.
nausea, vomiting, and diarrhoea).
Tell your doctor immediately if you have any thoughts about suicide or doing harm
to yourself.
Warning signs of suicide
If you or someone you know is showing the following warning signs, either contact
your doctor or a mental health advisor right away or go to the nearest hospital for
treatment.
All thoughts or talk about suicide or violence are serious.
thoughts or talk about death or suicide
thoughts or talk about self-harm or doing harm to others
any recent attempts of self-harm
an increase in aggressive behaviour, irritability or agitation.
Things you should not do
Do not suddenly stop taking ENLAFAX-XR or lower the dose, without first checking with
your doctor.
Check with your doctor for the best way to slowly reduce the amount of ENLAFAX-XR
you are taking before stopping completely.
If you stop taking it suddenly, your condition may worsen or you may have unwanted
side effects such as:
headache
nausea and vomiting
dizziness
insomnia
nervousness
anxiety
confusion and agitation
diarrhoea
sweating
loss of appetite
tremor
flu-like symptoms
impaired coordination and balance
tingling or numbness of the hands and feet.
Slowly reducing the amount of ENLAFAX-XR being taken reduces the possibility of these
effects occurring.
Some of these symptoms may impair driving, or the operation of dangerous machinery.
Avoid these activities if you experience these symptoms.
Do not take ENLAFAX-XR to treat any other complaints unless your doctor tells you
to.
Do not give this medicine to anyone else even if they have the same condition as you.
Driving or using machines
Be careful before you drive or use any machines or tools until you know how ENLAFAX-XR
affects you.
ENLAFAX-XR capsules may make you feel drowsy.
Things to be careful of
If you are feeling drowsy or are uncoordinated, be careful that you do not fall over.
ENLAFAX-XR, like other medicines in this class, may increase your risk of bone fracture.
Drinking alcohol
Avoid drinking alcohol while you are taking ENLAFAX-XR.
Alcohol can cause dizziness and lightheadedness. Alcohol may also worsen your condition.
Looking after your medicine
Store below 25°C
Keep your capsules in their blister pack until it is time to take them. If you take
the capsules out of the blister pack they may not keep well.
Follow the instructions in the carton on how to take care of your medicine properly.
Store it in a cool dry place away from moisture, heat or sunlight; for example, do
not store it:
in the bathroom or near a sink, or
in the car or on window sills.
Heat and dampness can destroy some medicines.
Keep it where young children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place
to store medicines.
Getting rid of any unwanted medicine
If you no longer need to take this medicine or it is out of date, take it to any pharmacy
for safe disposal.
Do not take this medicine after the expiry date.
6. Are there any side effects?
Tell your doctor or pharmacist as soon as possible if you do not feel well while you
are taking ENLAFAX-XR.
This medicine helps most people with depression, but it may have unwanted side effects
in some people.
All medicines can have side effects. Sometimes they are serious; often they are not.
You may need medical attention if you get some of the side effects.
It can be difficult to tell whether side effects are the result of taking this medicine,
