Consumer Medicine Information (CMI)
This leaflet provides important information about using INVEGA TRINZA. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using INVEGA TRINZA.
Where to find information in this leaflet:
1. Why am I using INVEGA TRINZA?
INVEGA TRINZA contains the active ingredient paliperidone palmitate. INVEGA TRINZA belongs to a group of medicines called antipsychotic agents which improve the symptoms of certain types of mental illness.
INVEGA TRINZA is used to treat adults with symptoms of schizophrenia, a mental illness with disturbances in thinking, feelings and behaviour.
INVEGA TRINZA helps to correct a chemical imbalance in the brain associated with this condition. It can also be used to lessen the chance of your schizophrenia symptoms from coming back.
Some of the most common symptoms of schizophrenia may include:
- Seeing, hearing, or sensing things that are not there (hallucinations)
- A false belief or wrong judgment, sometimes associated with hallucinations, held with conviction despite evidence to the contrary (delusions)
- Not trusting others and feeling very suspicious (paranoia)
- Avoiding family and friends and wanting to be alone
It may take some time before your symptoms of schizophrenia start to improve. Remember that INVEGA TRINZA is one part of your overall treatment plan. It is important to keep all your appointments, so you can get your treatments on time and your doctor can check your progress.
Your doctor, however, may prescribe this medicine for another use.
2. What should I know before I use INVEGA TRINZA?

As INVEGA TRINZA is given to you under the supervision of your doctor, it is very unlikely that you will receive too much.

You should immediately:

5. What should I know while using INVEGA TRINZA?
Things you should do
- Follow your doctor's instructions carefully.
- If you are planning to have operation on your eye, make sure you tell your eye doctor that you are taking this medicine.
- Ask your doctor or pharmacist before taking any other medicines.
INVEGA TRINZA can increase the effects of medicines which slow down 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.
Call your doctor straight away 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 INVEGA TRINZA. This condition is more likely to occur during longer term treatment and in older women. In very rare cases, these symptoms may be permanent. However, if detected early, these symptoms are usually reversible.
Remind any doctor, dentist or pharmacist you visit that you are using INVEGA TRINZA.
Things you should not do
- Do not miss an injection or stop the treatment suddenly without consulting your doctor first.
- Avoid excessive eating.
There is a possibility of weight gain when taking INVEGA. Your doctor may monitor your body weight or recommend strategies to assist with weight management.

Be careful before you drive or use any machines or tools until you know how INVEGA TRINZA affects you.
INVEGA TRINZA may cause dizziness, drowsiness or light-headedness in some people. Make sure you know how you react to INVEGA TRINZA 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.
Drinking alcohol
Do not drink alcohol.
INVEGA TRINZA can increase the effects of alcohol.
