1. What TREVICTA is and what it is used for TREVICTA contains the active substance paliperidone which belongs to the class of antipsychotic medicines and is used as a maintenance treatment for the symptoms of schizophrenia in adult patients.
If you have responded well to treatment with paliperidone palmitate injection given once a month, your doctor may start treatment with TREVICTA.
Schizophrenia is a disease with “positive” and “negative” symptoms. Positive means an excess of symptoms that are not normally present. For example, a person with schizophrenia may hear voices or see things that are not there (called hallucinations), believe things that are not true (called delusions), or feel unusually suspicious of others. Negative means a lack of behaviours or feelings that are normally present. For example, a person with schizophrenia may appear withdrawn and may not respond at all emotionally or may have trouble speaking in a clear and logical way. People with this disease may also feel depressed, anxious, guilty, or tense.
TREVICTA can help alleviate the symptoms of your disease and reduce the chance of your symptoms coming back.
2. What you need to know before you use TREVICTA Do not use TREVICTA
- if you are allergic to paliperidone or any of the other ingredients of this medicine (listed in section 6).
- if you are allergic to another antipsychotic medicine including the substance risperidone.
Warnings and precautions Talk to your doctor, pharmacist or nurse before using TREVICTA.

- if you have ever experienced twitching or jerking movements that you cannot control in your face, tongue, or other parts of your body (Tardive Dyskinesia)
- 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)
- if you are diabetic or prone to diabetes

- if you have kidney problems

Even if you have previously tolerated oral paliperidone or risperidone, rarely allergic reactions occur after receiving injections of TREVICTA. Seek medical attention right away if you experience a rash, swelling of your throat, itching, or problems breathing as these may be signs of a serious allergic reaction.

Since this medicine may reduce your urge to vomit, there is a chance that it may mask the body’s normal response to ingestion of toxic substances or other medical conditions.
During an operation on the eye for cloudiness of the lens (cataract), the pupil (the black circle in the middle of your eye) may not increase in size as needed. Also, the iris (the coloured part of the eye) may become floppy during surgery and that may lead to eye damage. If you are planning to have an operation on your eye, make sure you tell your eye doctor that you are taking this medicine.

Since this medicine can lower blood pressure, care should be taken when this medicine is used with other medicines that lower blood pressure.
This medicine can reduce the effect of medicines against Parkinson’s disease and restless legs syndrome (e.g., levodopa).
This medicine may cause an electrocardiogram (ECG) abnormality demonstrating a long time for an electrical impulse to travel through a certain part of the heart (known as “QT prolongation”). Other medicines that have this effect include some medicines used to treat the rhythm of the heart or to treat infection, and other antipsychotics.
If you have a history of seizures, this medicine may increase your chance of experiencing them. Other medicines that have this effect include some medicines used to treat depression or to treat infection, and other antipsychotics.

3. How to use TREVICTA This medicine is administered by your doctor or other health care professional. Your doctor will tell you when you need your next injection. It is important not to miss your scheduled dose. If you cannot keep your appointment with the doctor, make sure you call him right away so another appointment can be made as soon as possible.
Depending on your symptoms, your doctor may increase or decrease the amount of medicine you receive at the time of your next scheduled injection.
Patients with kidney problems If you have mild kidney problems your doctor will determine the appropriate dose of TREVICTA based on the dose of 1-monthly paliperidone palmitate injectable that you have been receiving. If you have moderate or severe kidney problems this medicine should not be used.

drowsiness or sedation, fast heart rate, low blood pressure, an abnormal electrocardiogram (electrical tracing of the heart), or slow or abnormal movements of the face, body, arms or legs.
