What Invega is used for
Invega belongs to a group of medicines called antipsychotic agents which improve the symptoms of certain type of mental illness.
It is used to treat symptoms of schizophrenia, a mental illness with disturbances in thinking, feelings and behaviour. It
is also used to treat other types of related psychoses. Invega helps to correct a chemical imbalance in the brain associated
with this condition.
Invega tablets are made in an extended release form. The tablets have a special shell that allows the release of the active
ingredient at a slow rate throughout the day. The tablet shell does not dissolve completely after all the drug has been released
and sometimes the tablet shell may be seen in your stool. This is normal.
Your doctor, however, may prescribe this medicine for another use.
Ask your doctor if you have any questions about why it has been prescribed to you.
Invega is not addictive.
