How to take this medicine
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ to the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist
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.
Standing up slowly, especially when you get up from bed or chairs, will help your
body get used to the change in position and blood pressure.
These symptoms should go away after a few days. Tell your doctor if they continue
or worry you.
How much to take
Your doctor or pharmacist will tell you how much of this medicine you should take.
This will depend on your condition and whether you are taking any other medicines.
Risperidone 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).
It is very important that you take the correct amount of risperidone, 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.
For schizophrenia and related psychoses in adults, adolescents and children aged over
15 years old:
The usual starting dose is one 1 mg tablet taken 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
For long-term treatment, 4 to 6 mg per day is usually sufficient, but your doctor
will determine the dose most suitable for you.
Important Note: Never take more tablets than your doctor tells you to take.
The effects of high doses are not yet known. Please double check with your doctor
if your doctor prescribes more than 5 mg twice a day.
Risperidone cannot be recommended for use in children with schizophrenia under 15
years as there is little experience with the product in this group.
For schizophrenia and related psychoses in elderly patients:
The usual starting dose is one 0.5 mg tablet taken twice a day.
The dose may be increased by 0.5 mg twice daily to 1 to 2 mg twice a day.
Patients who have impaired kidney or liver function:
The usual starting dose is one 0.5 mg tablet taken twice a day. The dose may be increased
by 0.5 mg twice daily to 1 to 2 mg twice a day.
For acute mania in patients with Bipolar 1 Disorder:
The usual starting dose is one 2 mg tablet once a day. This dose can be adjusted by
dose increases of 1 mg when needed every 24 hours. Most people feel better with doses
between 2 mg and 6 mg a day. Your doctor may also decide you should take another drug
called a mood stabiliser as well as risperidone.
For behavioural problems in people with dementia:
The usual starting dose is 0.25 mg (half a 0.5 mg tablet) taken 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 conduct and other disruptive disorders in adults, adolescents and children aged
over 5 years old who are intellectually disabled:
For people who weigh 50 kg or more, the usual starting dose is one 0.5 mg tablet taken
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 (half a 0.5
mg tablet) taken 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 risperidone you need.
Risperidone cannot be recommended for use in children under 5 years or age with disruptive
behaviour disorders 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 20 kg the usual starting dose is 0.25 mg (half a 0.5
mg tablet) daily. On Day 4, this dose can be increased to 0.5 mg.
For people weighing 20 kg or more the usual starting dose is 0.5 mg (0.5 mg tablet
or half a 1 mg tablet) daily. On Day 4, this dose can be increased to 1 mg.
After 14 days, the doctor should check that the tablets are working. The doctor will
say whether a higher dose is needed if the tablets do not seem to be have the desired
effect. Your doctor will advise you on how much risperidone you need.
In clinical trials, people with autism weighing less than 20 kg did not need more
than 1.5 mg/day. People weighing over 20 kg did not need more than 2.5 mg of risperidone
a day, and people weighing over 45 kg did not need more than 3.5 mg a day.
If you feel sleepy, then the doctor may split up your daily dose so that you take
half of it in the morning and half in the evening.
