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.

Before you take it

When you must not take it

Do not take Invega if you know you are allergic to any of its ingredients listed at the end of this leaflet or medicines containing risperidone (e.g. RISPERDAL). Signs of allergy include skin rash, itching, shortness of breath, and/or swollen face.

Do not take it after the expiry date printed on the pack. If you take it after the expiry date has passed, it may not work as well.

Do not take it if the packaging is torn or shows signs of being tampered with.

Do not take it if the tablets appearance has changed.

Do not take it to treat any other complaints unless your doctor says it is safe to do so.

Before you start to take it

Invega should be used with caution in some patients.

  1. Tell your doctor if you have or have ever had:
  • heart or blood vessel diseases, including low blood pressure
  • dehydration
  • epilepsy
  • restlessness or difficulty sitting still
  • intraoperative iris syndrome (a complication that may occur during cataract extraction)
  • suicide
  • disease of the pituitary gland
  • inflammation of the lungs due to aspiration (the inhalation of food particles or fluids into the lungs).
  • kidney or liver problems
  • Dementia or Lewy body dementia.
    INVEGA has not been studied in elderly patients with dementia. However, elderly patients with dementia, who are treated with other similar types of medicine, may have an increased risk of stroke or death.
  • Neuroleptic Malignant Syndrome (a serious reaction to some medicines with a sudden increase in body temperature, extremely high blood pressure and severe convulsions)
  • Tardive dyskinesia (a reaction to some medicines with involuntary movements of the tongue, face, mouth, jaws, arms, legs or trunk)
  • diabetes
  • disease of the blood vessels of the brain including stroke
  • swallowing, stomach or intestinal disorder that reduces your ability to swallow or pass foods by normal bowel movements
  • diseases associated with diarrhoea
  • priapism (continuous erection) and/or painful erection
  • low white blood cell count
    As dangerously low numbers of certain types of white blood cells needed to fight infection in your blood has been seen very rarely with patients taking INVEGA, your doctor may check your white blood cell counts. Tell your doctor if you have had low levels of white blood cells in the past (which may or may not have been caused by other medicines)
  • blood clots
    Tell your doctor if you or someone else in your family has a history of blood clots. Blood clots in the lungs and legs have been seen in patients taking INVEGA. Blood clots in the lungs can be fatal.
  1. Tell your doctor if:
  • you are pregnant or are planning to become pregnant. Your doctor will advise you whether or not you should take Invega.
    Shaking, muscle stiffness and/or weakness, sleepiness, agitation, breathing problems, and difficulty in feeding may occur in newborns, if you use Invega in your last trimester of pregnancy.
  • you are breast feeding. Invega is excreted in breast milk.
    It is recommended that you do not breast-feed while taking Invega.
  1. Other medicines and alcohol
    You should not drink alcohol while taking Invega.
Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
In particular tell your doctor if you are taking:
  • sleeping tablets, tranquillisers, pain-killers, antihistamines
  • medicines to treat epilepsy
  • medicines to treat depression, panic disorder, anxiety or obsessive-compulsive disorder.
  • diuretics
  • medicines for your heart or blood pressure
  • other medicines to treat mental illness or psychotic conditions
  • medicines to relieve severe nausea and vomiting.
  1. Elderly People
    In general your doctor would prescribe the same dose as for adult patients, but he/she may adjust the dose if you have diminished renal function.

Taking it for the first time

At the start of treatment you may have a fall in blood pressure making you feel dizzy on standing up, or your heart may beat faster. These should go away after a few days. Tell your doctor if they continue or worry you.
