Using RISPERDAL CONSTA
RISPERDAL CONSTA cannot be recommended for use in children and adolescents under 18
years at the present time as there is no experience with the product in this group.
How it is given
RISPERDAL CONSTA will be given to you by injection by a healthcare professional. It
is a medicine designed to gradually release the active ingredient in your body so
that you do not have to take this medicine every day.
The information for your doctor or nurse on the right way to reconstitute (make up)
RISPERDAL CONSTA is included in the package.
Your doctor or healthcare provider will give you the injection in the arm or buttock
every two weeks. Next time the injection will be given into the other arm or buttock,
and so on. Injection is not to be given intravenously.
The usual dose of RISPERDAL CONSTA is 25mg once every two weeks. Your doctor will
decide on the dose of RISPERDAL CONSTA that is right for you.
Because risperidone is released gradually into your body, you will need an injection
only every two weeks. During the first three weeks of treatment additional risperidone
tablets or liquid, which can be taken by mouth, must be used, because the first injection
will not start to work straight away. Your doctor will explain this to you.
Later, depending on how well the treatment is working, your doctor may decide to further
adjust the dose of RISPERDAL CONSTA or to add oral RISPERDAL (tablets or solution)
for a short time.
Do not stop your treatment just because you feel better.
If you have to stop RISPERDAL CONSTA on the advice of your doctor, it is best to do
it gradually. Stopping treatment suddenly may cause effects such as feeling sick,
vomiting, sweating, sleeplessness, muscle stiffness, or jerky movements, or your original
medical problem may come back.
Patients with kidney and liver problems.
RISPERDAL CONSTA has not been studied in patients whose kidney or liver is not working
properly. Your doctor will decide the dose suitable for you. A starting dose of 0.5mg
twice-daily oral risperidone is recommended during the first week. In the second week
1mg twice daily or 2mg once daily can be given. If a daily total oral dose of at least
2mg is well tolerated (i.e. the drug does not upset you), an injection of RISPERDAL
CONSTA can be administered every 2 weeks.
What if you missed a dose
It is very important to keep all your appointments and get your medicine on time.
Contact your doctor as soon as you can if you think you are going to miss or have
missed your appointment.
Your doctor will decide what you should do next.
As RISPERDAL CONSTA is given to you under the supervision of your doctor, it is very
unlikely that you will receive too much.
However, if you experience any side effects after being given RISPERDAL CONSTA, tell
you doctor immediately or go to Accident and Emergency at your nearest hospital.
You may need urgent medical attention.
