What VENLEXOR-XR is used for
VENLEXOR-XR capsules contain an active ingredient called "venlafaxine hydrochloride".
This medicine is used in the treatment and prevention of relapse of depression and in the treatment of social phobia (social anxiety disorder).
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 brain to work.
VENLEXOR-XR capsules increase the level of these two messengers. Experts think this is how it helps to restore your feeling of wellness.
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 and tension associated with the normal stress of daily life usually does not require treatment with medicines.
There is no evidence that VENLEXOR-XR is addictive.
Ask your doctor if you have any questions about why VENLEXOR-XR has been prescribed for you. Your doctor may have prescribed VENLEXOR-XR capsules for another purpose.

Tell your doctor or pharmacist if you are pregnant or intend to become pregnant. VENLEXOR-XR is not recommended for use during pregnancy. Your doctor will discuss the risks and benefits of using VENLEXOR-XR if you are pregnant.
One of these risks is that newborn babies whose mothers have been taking VENLEXOR-XR may have several problems soon after delivery, including breathing difficulties, high blood pressure, seizures and lack of oxygen in their blood.

Do not start to take any other medicine while you are taking VENLEXOR-XR, unless it is prescribed or approved by your doctor.
Some medicines and VENLEXOR-XR may interfere with each other. These include:
- Medications for depression known as monoamine oxidase inhibitors (such as 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.

How to take VENLEXOR-XR
DO NOT DIVIDE, CRUSH, CHEW OR DISSOLVE.
VENLEXOR-XR capsules are to be swallowed whole. Do not divide, chew, crush or place the capsules in water.
Inside VENLEXOR-XR capsules are tablets that contain the venlafaxine active ingredient. As the medicine travels the length of your gastrointestinal tract, venlafaxine is slowly released.
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
The usual starting dose is 75mg taken once daily. If necessary, after two weeks, your doctor may increase your dose.
Do not change the dose unless your doctor tells you to.
If you have kidney or liver problems, you may need a lower dose of VENLEXOR-XR.
If you have heart problems and your doctor wishes to increase your dose of VENLEXOR-XR, your doctor may first do some blood tests or heart tests such as an electrocardiogram (ECG).
When to take it
VENLEXOR-XR should be taken once daily with food, at approximately the same time each day. This could be either in the morning or in the evening.
Avoid drinking alcohol while you are using VENLEXOR-XR.
Your doctor may have switched your treatment from Venlafaxine Hydrochloride tablets to VENLEXOR-XR capsules. If this happens, your doctor will normally prescribe a dose that is equivalent to your total daily dose of tablets. The dose of VENLEXOR-XR capsules should be taken only once daily.
If you forget to take it
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.
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 when to take your medicine, ask your pharmacist for some hints.
How long to take it for
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, you will usually have to take VENLEXOR-XR for several months or even longer to make sure the benefits will last.
Discuss this with your doctor and don't stop taking VENLEXOR-XR until gaining your doctor's agreement.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much VENLEXOR-XR.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Keep telephone numbers for these places handy. Take the pack of capsules with you to the doctor or hospital.
If you take too many VENLEXOR-XR capsules you may:
- Feel sleepy
- Have an increased heart rate or changes in heart rhythm
- Have a seizure (fit)
- Have breathing difficulties
- Become unconscious
- Have dilated pupils.
