What RISPERDAL is used for
Risperdal belongs to a group of medicines called antipsychotic agents which improve the symptoms of certain types of mental
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. If
you want more information, ask your doctor. It is only available with a doctor's prescription.
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 (signs of allergy include skin rash, itching, shortness of breath,
and/or swollen face - see the last section of this leaflet for a list of ingredients)
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.
Tell your doctor if you have or have ever had any medical conditions, especially the following:
heart or blood vessel problems, including high and low blood pressure.
Low blood pressure can result from using RISPERDAL together with medications to treat high blood pressure. So, if you need
to use both RISPERDAL and medications to reduce blood pressure, consult your doctor.
RISPERDAL should be used with caution, and only after consultation with your doctor, if you have heart problems, particularly
irregular heart rhythm, abnormalities in electrical activity of the heart, or if using medications that can change the heart's

low blood sugar
disease of the pituitary gland
Tardive dyskinesia (a reaction to some medicines with uncontrollable twitching or jerking movements of the arms and legs)
Neuroleptic Malignant Syndrome (a serious reaction to some medicines with a sudden increase in body temperature, extremely
high blood pressure and severe convulsions).
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 RISPERDAL. Blood clots in the lungs can be fatal.
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 RISPERDAL, your doctor may check your white blood cell counts. Tell your doctor if you know that
you have had low levels of white blood cells in the past (which may or may not have been caused by other medicines).

your reactions. These include herbal treatments and those bought in a pharmacy or supermarket.
Tell your doctor if you are taking:
diuretics like frusemide (trade names LASIX, UREMIDE, UREX, FRUSID, or FRUSEHEXAL), a drug used to treat high blood pressure,
or to treat swelling of parts of the body caused by the build-up of too much fluid, There is an increased risk of side effects
or death in elderly people if frusemide is also taken with RISPERDAL.

antibiotics like rifampicin
carbamazepine, a drug mainly used for epilepsy or trigeminal neuralgia (severe pain attacks in the face) may decrease the
level of RISPERDAL in your blood.
Anti-fungals like itraconazole and ketoconazole,
medicines to treat Parkinson's disease or a tremor
medicines to treat epilepsy
medicines to treat depression, panic disorder, anxiety or obsessive-compulsive disorder. For example, fluoxetine and paroxetine

The maximum daily dose of RISPERDAL 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.
RISPERDAL 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.

The usual starting dose of RISPERDAL is 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 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 RISPERDAL.

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,

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

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.

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
RISPERDAL. This condition is more likely to occur during long term treatment with RISPERDAL, 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 RISPERDAL.
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

RISPERDAL can increase the effects of alcohol.
Things to be careful of
Be careful driving or operating machinery until you know how RISPERDAL affects you.
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.
