Consumer Medicine Information

What is in this leaflet

This leaflet answers some of the common questions about RISPERDAL. It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

If you have any concerns about using RISPERDAL, ask your doctor or pharmacist. Your doctor and pharmacist have more information.

Keep this leaflet with your medicine. You may need to read it again.

What RISPERDAL is used for

RISPERDAL belongs to a group of medicines called antipsychotic agents which improve the symptoms of certain types of mental illness.

It is used for:

  • treatment of sudden (acute) and long-term (chronic) schizophrenia and other types of related psychoses. These are disorders related to thought, feeling and/or action,
  • short term treatment of acute mania associated with bipolar 1 disorder. This condition is characterised by symptoms such as elevated, expansive or irritable mood, inflated self-esteem, decreased need for sleep, pressured speech, racing thoughts, distractibility or poor judgement including disruptive or aggressive behaviours,
  • treatment of behavioural problems in patients with a decline in mental ability (dementia) caused by Alzheimer’s disease. These problems include: aggression through words or action, morbid suspiciousness, agitation or wandering,
  • treatment of conduct and other disruptive behaviours such as aggression, impulsiveness and self-injury in children (over 5 years old), adolescents and adults who are intellectually disabled,
  • treatment of behavioural symptoms of autism in children and adolescent.

RISPERDAL helps to correct a chemical imbalance in the brain associated with these conditions.

This medicine has been approved for the uses mentioned above. However, your doctor may prescribe it for another use. It is only available with a doctor’s prescription.

If you want more information, ask your doctor.

RISPERDAL is not addictive.

Before you use RISPERDAL

When you must not use it

Do not use RISPERDAL:

  • if you know you are allergic to any of its ingredients (see the last section of this leaflet for a list of ingredients)
    Signs of allergy include skin rash, itching, shortness of breath, and/or swollen face
  • if the packaging is torn or shows signs of being tampered with
  • if the tablets or the oral solution do not look right
  • to treat any other complaints unless your doctor says it is safe to do so.

Before you start to use it

RISPERDAL should be used with caution in some patients.

  1. Tell your doctor if you have or have ever had any medical conditions, especially the following:
  • irregular heart rhythm, abnormalities in electrical activity of the heart, high or low blood pressure, or you’ve had a heart attack or stroke in the past.
  • unusual excessive sweating or diarrhoea, dehydration or problems with your body temperature regulation
  • kidney or liver problems
  • you are prone to dizziness when standing up from lying or sitting position
  • Parkinson’s disease (a progressive movement and thinking disorder that tends to affect older people)
  • dementia or Lewy body dementia
    Older people suffering dementia may be at increased risk of stroke or death with RISPERDAL
  • sugar diabetes
  • unusual thirst, tiredness, blurred vision, upset stomach or need to urinate – common signs of high blood sugars
  • epilepsy, seizures or fits
  • continuous and/or painful erections (called ‘priapism’)
  • involuntary movements or unusual restlessness or difficulty sitting still
  • suicidal thoughts or past suicide attempts
  • low blood potassium levels (hypokalaemia)
  • breast cancer
  • cancer of the pituitary gland
  • Tardive dyskinesia (a reaction to some medicines with uncontrollable twitching or jerking movements of the tongue, face, mouth, jaw, arms and legs)
  • Neuroleptic Malignant Syndrome (a serious reaction to some medicines that causes sudden increase in body temperature, very fast heartbeat, extremely high or low blood pressure and severe muscle stiffness or fits).
  • 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 can occur with RISPERDAL. Blood clots in the lungs can result in death.
  • low white blood cell count
    If you have low numbers of some white blood cells, your risk of contracting an infection or developing a fever is increased with RISPERDAL.

  1. Tell your doctor if:
  • you have any eye surgery planned.
    Your doctor will need to assess whether you are at risk of a surgical complication (called ‘Intraoperative Floppy Iris Syndrome). You may be recommended to stop your RISPERDAL temporarily prior to your eye surgery.
  • you are pregnant or planning to become pregnant.
    Your doctor will advise you whether you should take RISPERDAL.
    Newborn babies of mother taking RISPERDAL in their last trimester may be at risk of having difficulty feeding or breathing, shaking, muscle stiffness and/or weakness, sleepiness or agitation.
  • you are breast-feeding.
    As RISPERDAL is excreted in breast milk, it is recommended that you do not breast-feed while taking the medicine.
  • you will be in a hot environment or do a lot of vigorous exercise.
    RISPERDAL may make you sweat less, causing your body to overheat.

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking RISPERDAL.

Taking other medicines

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, strong pain-killers, certain allergy medicines called antihistamines, certain antidepressants and alcohol
  • medicines that increase the activity of the central nervous system (psychostimulants such as methylphenidate).
  • medicines used to treat bacterial infections such as rifampicin
  • medicines to treat fungal infections such as itraconazole and ketoconazole
  • medicines to treat HIV/AIDS, such as ritonavir and tipranavir
  • other medicines to treat mental illness or psychotic conditions
  • medicines to treat depression, panic disorder, anxiety or obsessive-compulsive disorder, such as fluoxetine, paroxetine, sertraline and fluvoxamine
  • medicines for your heart or blood pressure
  • verapamil, a medicine used to treat high blood pressure and/or abnormal heart rhythm
  • furosemide, a medicine used to treat high blood pressure and fluid build-up.
    There is an increased risk of side effects or death in older people if furosemide is also taken with RISPERDAL.
  • medicines to treat epilepsy
  • carbamazepine, a drug mainly used for epilepsy or trigeminal neuralgia (severe pain attacks in the face)
  • medicines to treat Parkinson’s disease or a tremor.

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.

How to take it


Swallow RISPERDAL tablets with water or other liquid.

RISPERDAL oral solution

Mix RISPERDAL oral solution with a non-alcoholic drink.

Mineral water, orange juice, coffee and milk are suitable. Do not use tea.

It is very important that you take the correct amount of RISPERDAL, but this will vary from person to person. Your doctor will adjust the dose and strength of the tablets or the amount of solution until the desired effect is obtained.

How to use

Directions for opening the bottle and using the pipette for RISPERDAL Oral Solution

Step 1:
The bottle comes with a child-resistant cap.

To open, push the screw cap down while turning it anti-clockwise. Remove the unscrewed cap.

Step 2:
Use the pipette from the container. While holding the bottom ring, pull the top ring up to the mark that corresponds to the dose you need.

Step 3:
Holding the bottom ring, remove the entire pipette from the bottle.

Step 4:
Empty the contents of the pipette into a non-alcoholic drink by sliding the upper ring down. Mineral water, orange juice, coffee and milk are suitable. Do not use tea.

Step 5:
Close the bottle. Rinse the pipette with some cold water after use, dry and store it in its case. Use of detergents or extensive rubbing with a cloth may increase the risk of fading or disappearing print.

How long to take it

Continue taking the tablets or solution for as long as your doctor tells you.

RISPERDAL helps control your condition but does not cure it. Therefore, you must take RISPERDAL every day.

Do not stop taking it unless your doctor tells you to – even if you feel better.

If you forget to take RISPERDAL

  • If you forget to take RISPERDAL, take the missed dose as soon as you remember instead of your next dose. Then go back to taking it as you would normally.
  • Do not take a double dose to make up for the one you missed.
  • If you forget to take RISPERDAL for a number of days or more, tell your doctor before starting your medicine again.

If you have problems remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much

Immediately telephone your doctor or the Poisons Information Centre or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much RISPERDAL. Do this even if there are no signs of discomfort or poisoning.

You can contact the Poisons Information Centre by dialling:

  • Australia: 13 11 26
  • New Zealand: 0800 POISON or 0800 764 766.

Signs of overdose may include drowsiness, sleepiness, excessive trembling, excessive muscle stiffness, increased heart rate, very low blood pressure causing fainting or unconsciousness.

While you are using RISPERDAL

Things you must do

Always follow your doctor’s instructions carefully and seek your doctor’s advice before changing or stopping treatment. Your doctor will be happy to discuss any questions you may have with your treatment.

Tell all doctors, dentists, and pharmacists who are treating you that you are taking RISPERDAL.

Tell your doctor if you are not pregnant or planning to become pregnant.

If you are pre-menopausal, tell your doctor if you do not have a period for more than six months while using RISPERDAL, even if you are not pregnant.

Tell your doctor immediately if you notice any involuntary movements of the tongue, mouth, cheeks or jaw which may progress to the arms and legs. These may be symptoms of a condition called Tardive Dyskinesia, which can develop in people taking antipsychotic medicines, including RISPERDAL. This condition is more likely to occur during longer term treatment and in older women. In very rare cases, these symptoms may be permanent. However, if detected early, these symptoms are usually reversible.

Be careful during strenuous exercise or exposure to extreme heat. Try to drink plenty of water.

Do not drink alcohol. RISPERDAL can increase the effects of alcohol.

Things to be careful of

Ask your doctor or pharmacist before taking any other medicines.

RISPERDAL can increase the effects of medicines which slow your reactions. Always ask your doctor or pharmacist before taking other medicines, including herbal treatments and medicines that can be bought in a pharmacy or supermarket.

Avoid driving or operating machinery until you are sure RISPERDAL does not affect your alertness. RISPERDAL may cause dizziness or light-headedness in some people, especially after the first dose. Make sure you know how you react to RISPERDAL before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy.

If the medicine makes you feel light-headed, dizzy or faint, be careful when getting up from a sitting or lying position. Getting up slowly may help.

Avoid excessive eating. There is a possibility of weight gain when taking RISPERDAL. Your doctor may monitor your body weight or recommend strategies to assist with weight management.

All medicines can have some unwanted side effects. Sometimes they are serious, but most of the time they are not. Your doctor has weighed the risks of using this medicine against the benefits they expect it will have for you.

All medicines can have side effects. You may need medical treatment if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.
