What this medicine is used for

The name of your medicine is Terry White Chemists Venlafaxine XR Capsules. It contains the active ingredient venlafaxine (as venlafaxine hydrochloride).
It is used to treat major depression, and to prevent it coming back. It is also used in the treatment of panic attacks and anxiety, including avoidance or fear of social situations.

How it works

Depression can affect your whole body and may cause emotional and physical symptoms such as feeling low in spirit, being unable to enjoy life, poor appetite or overeating, disturbed sleep, loss of sex drive, lack of energy and feeling guilty over nothing.
Excessive anxiety is a condition in which you feel constantly and uncontrollably worried and distressed. It may also make you feel irritable, and cause difficulty in thinking and sleeping. Other common symptoms associated with anxiety may include a dry mouth, a lump in the throat, cold clammy hands, diarrhoea and nausea.
Depression and anxiety are treatable illnesses. Anxiety or tension associated with the normal stress of everyday life usually does not require treatment with medicines.
Venlafaxine belongs to a class of medications for depression, called Serotonin-Noradrenaline Reuptake Inhibitors (SNRIs).
Serotonin and noradrenaline are chemical messengers that allow certain nerves in the brain to work.
Venlafaxine increases the level of these two messengers. Experts think this is how it helps to restore your feeling of wellness.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed Venlafaxine XR for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.

Use in children

Do not give venlafaxine to children or adolescents under 18 years of age.
The safety and effectiveness of venlafaxine in this age group have not been established.

Before you take this medicine

When you must not take it

Do not take this medicine if you are taking other medicines called Monoamine Oxidase Inhibitors (MAOIs). These may be used for the treatment of depression (phenelzine, tranylcypromine, moclobemide), Parkinson's disease (selegiline) or infections (linezolid) or diagnosis of certain conditions/treatment of certain blood disorders (methylene blue).
There may be others so check with your doctor or pharmacist.
Do not take venlafaxine until 14 days after stopping most MAOIs, and do not take any MAOIs until more than one week after stopping venlafaxine (see also point 7 in "Before You Start to Take it").
(However you may take venlafaxine 24 hours after stopping the reversible MAOI called moclobemide.)
Taking venlafaxine with a MAOI may cause a serious reaction with a sudden increase in body temperature, extremely high blood pressure and severe convulsions.
Do not take this medicine if:
The expiry date (EXP) printed on the pack has passed.
The packaging is torn, shows signs of tampering or it does not look quite right.

How to take this medicine

Follow carefully all directions given to you by your doctor or pharmacist. Their instructions may be different to the information in this leaflet.

How much to take

Your doctor or pharmacist will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
The usual starting dose is 75 mg taken once daily.
If necessary, after two weeks, your doctor may increase your dose. The maximum you should take in one day is 225 mg.
The dose may be much lower if you have liver or kidney problems.
If you have kidney or liver problems, you may need a lower dose of venlafaxine.
If you have heart problems and your doctor wishes to increase your dose of venlafaxine, your doctor may first do some blood tests or heart tests such as an electrocardiogram (ECG).
Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the capsules whole with a glass of water or other non-alcoholic liquid. Do not divide, crush, chew or place the capsules in water.
Inside Venlafaxine XR capsules are tablets that contain the venlafaxine active ingredient. As the medicine travels the length of your gastrointestinal tract, venlafaxine is slowly released.

When to take it

Take venlafaxine once daily with food, either in the morning or in the evening.
Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.
Avoid drinking alcohol while you are taking venlafaxine.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.
Although you may begin to feel better after two weeks, it may take several weeks before you feel much better. It is important to give venlafaxine time to work.
Even when you feel well again, you may need to keep taking venlafaxine for several months to make sure the benefits last. Discuss this with your doctor and do not stop taking venlafaxine until gaining your doctor's agreement.
Make sure you have enough to last over weekends and holidays.

If you forget to take it

If it is less than 12 hours until your next dose, skip the missed dose and take your next dose at the usual time. Otherwise take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
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 have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much venlafaxine, you may:
Feel sleepy
Vomit
Have an increased heart rate or changes in heart rhythm
Have a seizure (fits)
Have breathing difficulties

While you are taking this medicine

Things you must do

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.
Tell your doctor immediately if you have any thoughts about suicide or doing harm to yourself.

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.
Tell your doctor that you are taking this medicine if:
you are about to be started on any new medicine
you become pregnant.
Make sure your midwife and/or doctor know immediately that you are pregnant and taking venlafaxine, as there is a possibility of problems developing in unborn children. Symptoms such as feeding difficulty, vomiting, tremor, irritability and constant crying have been reported rarely in newborn babies after mothers have taken venlafaxine in the last 3 months of pregnancy. In addition, when taken particularly in the last 3 months of pregnancy, medicines like venlafaxine 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.
you are breastfeeding or are planning to breastfeed
you are about to have any blood tests
you are going to have surgery or an anaesthetic or are going into hospital.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects. Go to your doctor regularly for a check-up.
Some people (especially older people and/or those taking diuretics/water tablets) may experience a lack of sodium in the blood when taking this medicine. Tell your doctor if you get a headache or start to feel dizzy, confused, forgetful, weak, unsteady or unable to concentrate. Make sure to drink plenty of fluids.
If you are being treated for depression, be sure to discuss with your doctor any problems you may have and how you feel, especially any feelings of severe sadness, thoughts of suicide, bursts of unusual energy, anger or aggression, or if you become particularly agitated or restless.
This will help your doctor to determine the best treatment for you.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.

Things you must not do

Do not:
Give this medicine to anyone else, even if their symptoms seem similar to yours
Take your medicine to treat any other condition unless your doctor or pharmacist tells you to
Stop taking your medicine, or change the dosage, without first checking with your doctor
