What RISPERDAL CONSTA is used for?

RISPERDAL CONSTA is used to treat symptoms of schizophrenia and other types of related psychoses. These are disorders related to thought, feeling and/or action.

RISPERDAL CONSTA is also used to treat bipolar disorder to prevent or delay mood swings which consist of alternating periods of high (manic) or elevated mood with periods of depression. During the manic episodes you may feel very excited, elated, agitated, enthusiastic, or hyperactive, or have poor judgment including disruptive or aggressive behaviours. During the episodes of depression you may experience sadness, low energy, lack of motivation, feelings of guilt and worthlessness, and changes in sleep or appetite.

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

RISPERDAL CONSTA has been approved for the uses mentioned above. However, your doctor may prescribe this medicine for another use.

If you want more information, ask your doctor.

RISPERDAL CONSTA is not addictive.

Using it for the first time

Treatment with RISPERDAL CONSTA will not be started until it is known that you can tolerate RISPERDAL treatment by mouth (tablets or oral solution).

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 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.

Overdose

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.

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 CONSTA

Things you must do

Always follow your doctor's instructions carefully. Do not miss an injection or stop the treatment without consulting your doctor first. 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 using RISPERDAL CONSTA.

If you become pregnant while using RISPERDAL CONSTA, tell your doctor.

Pre-menopausal women should tell their doctor if they do not have a period for more than six months while using RISPERDAL CONSTA, even if they 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 CONSTA. This condition is more likely to occur during longer treatment 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 CONSTA can increase the effects of alcohol.

Things to be careful of

Ask your doctor before taking any other medicines. RISPERDAL CONSTA 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 CONSTA does not affect your alertness. RISPERDAL CONSTA may cause dizziness or light-headedness in some people, especially after the first dose. Make sure you know how you react to RISPERDAL CONSTA 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 using RISPERDAL CONSTA. Your doctor may monitor your body weight or recommend strategies to assist with weight management.

Side Effects

All medicines can have 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.
