What this medicine is used for
The name of your medicine is APO-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
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.
