What Altven is used for
What it does
Altven is used in the treatment and prevention of relapse of depression. It is also used in the treatment of panic attacks
and anxiety, including avoidance or fear of social situations.
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.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
How it works
Altven contains the active ingredient called 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. Altven capsules increase
the level of these two messengers. Experts think this is how it helps to restore your feeling of wellness.
Altven is not addictive.
It is available only with a doctor's prescription.
Use in Children
Do not give Altven to children or adolescents under 18 years of age.
The safety and effectiveness of Altven in this age group have not been established.

How to take Altven
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.
Depression and Anxiety
The usual starting dose is 75 mg taken once daily. After 2 weeks, your doctor may increase the dose to 150 mg a day.
The usual starting dose is 37.5 mg taken once daily for the first 4 to 7 days, then increased to 75 mg taken once daily.
Do not change your dose unless your doctor tells you to.
If you have kidney or liver problems, you may need a lower dose of Altven.
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 Altven.
How to take it
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.
Do not be concerned if you see small white granules or balls in your stools after taking Altven.
Inside Altven capsules are spheroids or small white balls that contain the venlafaxine active ingredient. These spheroids
are released from the capsule into your gastrointestinal tract. As the spheroids travel the length of your gastrointestinal
tract, venlafaxine is slowly released. The spheroid 'shell' remains undissolved and is eliminated in your stools. Therefore,
even though, you may see spheroids in your stools, your dose of venlafaxine has been absorbed.
When to take it
Take your medicine 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.
Avoid drinking alcohol while you are taking Altven.
How long to take it
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 Altven time to work.
This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if
you feel well.
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.
This may increase the chance of you getting an unwanted side effect.
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 (overdose)
Immediately telephone your doctor or Poisons Information Centre (Tel 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 Altven.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.

Have an increased heart rate or changes in heart rhythm
Have a seizure (fits)
Have breathing difficulties
Have dilated pupils.
