The name of your medicine is Chemmart Venlafaxine XR. It contains the active ingredient venlafaxine (as venlafaxine hydrochloride).
It is used to treat major depression, and to prevent it coming back.
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.
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.
