What Rispa Tablets is used for

RISPA 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.

RISPA 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.

RISPA is not addictive.

Before you use Rispa Tablets

When you must not use it

Do not use RISPA:

  • 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

RISPA 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 RISPA
  • 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 RISPAL. 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 RISPA.
  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 RISPA temporarily prior to your eye surgery.
  • you are pregnant or planning to become pregnant.
    Your doctor will advise you whether you should take RISPA.
    Newborn babies of mother taking RISPA 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 RISPA 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.
    RISPA 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 RISPA.

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
  • frusemide, 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 frusemide is also taken with RISPA.
  • 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.
  • medicines to treat epilepsy

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.

Using Rispa Tablets

How much to take

Your doctor will decide the dose suitable for you.

Follow your doctor’s instructions carefully and do not change or stop the required dosage without consulting your doctor first.

Important note:

Never take more tablets than your doctor tells you to take. The maximum daily dose of Rispa tablets is 5 milligrams taken twice a day. Check with your doctor if more than this has been prescribed. The effects of high doses are not yet known.

Rispa tablets cannot be recommended for use in children with schizophrenia under 15 years at the present time as there is little experience with the product in this group.

For Schizophrenia and Related Psychoses
The usual starting dose of Rispa tablets are 1 mg twice a day. This will be gradually increased by your doctor to suit your needs.

From then on, the dose can be taken once a day or twice a day according to your doctor’s instructions. For long-term treatment, 4 to 6 milligrams per day is usually sufficient but your doctor will determine the dose most suitable for you.

For Elderly Patients with Schizophrenia or Related Psychoses
For older patients a starting dose of 0.5 mg twice a day (in the morning and in the evening is usual). The dose may be increased by 0.5 mg twice daily to 1 to 2 mg twice a day (in the morning and in the evening).

Patients with impaired kidney and liver function
If you have kidney or liver disease a starting dose of 0.5 mg twice a day (in the morning and in the evening) is usual. The dose may be increased by 0.5 mg twice daily to 1 to 2 mg twice a day (in the morning and in the evening).

For acute mania
The recommended starting dose is 2mg once a day. This dose can be adjusted by dose increases of 1mg when needed every 24 hours. Most people feel better with doses between 2mg and 6mg a day. Your doctor may decide you should take another drug called a mood stabiliser as well as Rispa Tablets.

For Behavioural Problems in People with Dementia
The usual starting dose is 0.25 mg twice daily. This may be gradually increased by your doctor to suit your needs.

From then on the dose can be taken once a day or twice a day according to your doctor’s instructions. For long-term treatment, 1 mg daily is the usual dose but your doctor will determine the dose most suitable for you.

For Disruptive Behaviour Disorders in Adults and Children
For people who weigh 50 kg or more, the usual starting dose is 0.5 mg once a day. The dose may be increased by 0.5 mg once every two days, to the usual dose of 0.5 to 1.5 mg once a day.

For people who weigh less than 50 kg, the usual starting dose is 0.25 mg once a day. The dose may be increased by 0.25 mg once every two days, to the usual dose of 0.25 to 0.75 mg once a day.

Your doctor will advise you on how much Rispa tablets you need.

Rispa tablets cannot be recommended for use in children with disruptive behaviour disorders under 5 years at the present time as there is little experience with the product in this group.

For Behavioural Disorders Associated with Autism in Children and Adolescents
For people weighing less than 20kg the usual starting dose is 0.25mg. On day 4 this dose can be increased to 0.5mg.

For people weighing 20kg or more the usual starting dose is 0.5mg. On day 4 this dose can be increased to 1.0mg.

Response should be assessed at day 14; only in patients not achieving sufficient clinical response should additional dose increases be considered. Your doctor will advise you on how much Rispa tablets you need. When trialled, the maximum dose in patients with autism did not exceed 1.5mg/day in patients less than 20kg, 2.5mg in patients 20kg or more, or 3.5mg in patients more than 45kg.

When to take it

Rispa tablets may be taken as a single dose, once a day or it may be taken in divided doses twice a day (in the morning and in the evening). You may take Rispa tablets either with or between meals.

How to take it

Swallow Rispa tablets with water or other liquid.

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

As the 0.5 mg risperidone tablets do not have a breakline, they must not be broken in half to give a 0.25 mg dose. If you have been prescribed with 0.25 mg dose, consult your doctor or pharmacist for the alternative products.

How long to take it

Continue taking the tablets for as long as your doctor tells you. Rispa tablets helps control your condition, but does not cure it.

Therefore you must take Rispa tablets every day.

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

If you forget to take Rispa tablets

  • If you forget to take Rispa tablets, 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 Rispa tablets for 5 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 Rispa tablets. 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 Rispa Tablets

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.

Try to eat a moderate diet. Rispa tablets can cause weight gain.

You should make sure you are not pregnant.

Pre-menopausal women should tell their doctor if they do not have a period for more than six months while taking Rispa tablets.

Tell your doctor immediately if you notice any worm-like movements of the tongue, or other uncontrolled movements of the tongue, mouth, cheeks or jaw which may progress to the arms and legs. These are symptoms of a condition called tardive dyskinesia, which may develop in people taking antipsychotic medicines, including Rispa tablets. This condition is more likely to occur during long term treatment with Rispa tablets, especially in elderly women. In very rare cases, this may be permanent. However, if detected early, these symptoms are usually reversible.

Tell any other doctors, dentists, and pharmacists who are treating you that you are taking Rispa tablets.

Try to drink plenty of water, especially if you are elderly and taking frusemide (a diuretic). This will help decrease your risk of certain side effects.

Things you must not do

Do not drink alcohol. Rispa tablets can increase the effects of alcohol.

Things to be careful of

Be careful driving or operating machinery until you know how Rispa tablets affects you. Rispa tablets may cause dizziness or light-headedness in some people, especially after the first dose. Make sure you know how you react to Rispa tablets before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy.

Avoid excessive eating, as there is a possibility of weight gain when taking Rispa tablets.
