1. WHAT XENALVEN XL CAPSULES ARE AND
WHAT ARE THEY USED FOR
Xenalven XL is an antidepressant and one of a group of
medicines called serotonin noradrenaline reuptake inhibitors (SNRIs). This group of medicines is used to treat
depression. It is thought that people who are depressed
may have lower levels of serotonin and noradrenaline in
their brain. Whilst it is not fully understood how antidepressants work, Xenalven XL prolonged release capsules
may help to relieve the symptoms of depression by
increasing the levels of these substances in the brain.
Xenalven XL capsules is a treatment for adults with
depression. Xenalven XL capsules is also a treatment for
adults with the following anxiety disorders: generalised
anxiety disorder, social anxiety disorder (fear or avoidance
of social situations) and panic disorder (panic attacks).
Treating depression or anxiety disorders properly is important to help you get better. If it is not treated, your condition
may not go away and may become more serious and more
difficult to treat.

of this medicine (listed in section 6).

depression or Parkinson’s disease. Taking an irreversible

effects. Also, you must wait at least 7 days after you stop
taking Xenalven XL before you take any MAOI (see
also the section "Taking other medicines" and the
information in that section about "Serotonin Syndrome")

two weeks but sometimes longer.

4. POSSIBLE SIDE EFFECTS
Like all medicines, Xenalven XL can cause side effects,
although not everybody gets them.
Do not be concerned if you see small white granules or
balls in your stools after taking Xenalven XL. Inside
Xenalven XL capsules are spheroids or small white balls
that contain the Xenalven XL active ingredient. These
spheroids are released from the capsules into your
gastrointestinal tract. As the spheroids travel the length
of your gastrointestinal tract, Xenalven XL 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 Xenalven
XL has been absorbed

XL. Tell your doctor immediately, or go to the casualty
department at your nearest hospital:

Syndrome (NMS). Signs and symptoms of NMS may
include a combination of fever, fast heart beat, sweating,
severe muscle stiffness, confusion, increased muscle
enzymes (determined by a blood test).
Serious side effects
If you notice any signs of the following, you may need
urgent medical attention:

agitation, and sweating, or if you experience jerky
